    how are C Background tasks started?

    in Power PMAC

    Posted

    there are a couple of interesting fact on the system command behavior. So, the real command to send to the linux is:

    system nohup /usr/local/bin/ads/capp1.out &> /var/log/ADS.txt &

     

    the syntax, without quote, works in a strange way: the terminal of the IDE does not responds anymore to commands, unless I hit CTRL+C. Then, it disconnects and reconnect, and I have my capp1.out running in background and the IDE responding to command.

    If I use the system command with the quotes " , it still reply me with the error message

    sh: -c: line 0: unexpected EOF while looking for matching `"'
sh: -c: line 1: syntax error: unexpected end of file

     

    What am I doing wrong? How can I make my software run in background at project startup?

    Hi all

     

    I'd like to run my C software in background and log the output (the printf output) on a text file.

    The shell command should be: 

    /usr/local/bin/ads/capp1.out &> /var/log/ADS.txt

     

    I tried to use the system and cpx system commands, but I constanly get an error message; it seems it doesn't like the string with the ampersand character; if I issue the command in the terminal window, I get this error:

     

    sh: -c: line 0: unexpected EOF while looking for matching `"'

     

    What should I do to run the sw?

     

    ciao

    C++ background apps?

    in Power PMAC

    Posted

    Hi All

    the application (compiled under the PMAC) is working fine; the time for this project is running out, so I don't think I will have time to spent to compile it under the windows machine.

     

    Now I'd like to start the application automatically as a background process, at the startup of the PMAC.

     

    Is there any particular way to start this application, or should I go with the classic init.d scripts? What does it do the "Run At Startup" flag on the IDE?

     

     

    --edit:

    I found the answer here:

    Kinematics in CfromScript - RealTime Routines from network bug?

    in Power PMAC

    Posted

    Hi all

    I am writing the kinematics of an hexapod system.

    Reading through the forum, it seems that it is advisable using the CfromScript functions instead of the builtin kinematics scripts. I feel also more comfortable in writing the algorithm in C, so this is a big deal.

     

    Unfortunately, I got a strange error when I try to compile the RealTime Routines under the IDE:

     

    		Build Process For usralgo.ko has started.
Z:\100_XXX_hexapod\electronics\XXX2\XXX2\XXX2.ppproj(187,5): Error : cp: target `Routines' is not a directory
	Build Process For usralgo.ko has ended.

     

    At first I tought of a white-space character issue in some compilation layer... However, I tryed to copy the full directory folder on my desktop and re-perform the compilation of the project... and it works! I got other kind of compilation errors (i think because I am using the default usralgo.c, without any modification), but at least the result is different.

     

    		Build Process For usralgo.so has started.

    Is that because the project is located on a network disk, linked under Z:/ ? Is there some path to make it work from the network?

    Hi shansen

     

    many thanks for all the clarification.

    Unfortunately, I need to move to another part of the project, so I don't have time now to make work the compilation under the windows machine. I will get back there in a couple of weeks, I hope. For the moment, I will keep going with the direct compilation of the code under the linux machine.

     

    Many thanks to everyone!

    I forgot that in order to use the bash shell in Cygwin, you will may need to set your Windows "Path" environment variable before opening bash.exe.

     

    Specifically, you need to add the following two paths to the PATH variable:

     

    C:\Program Files (x86)\Delta Tau Data Systems Inc\2.0\Power PMAC Suite\powerpc-460-linux-gnu\bin

     

    C:\Program Files (x86)\Delta Tau Data Systems Inc\2.0\Power PMAC Suite\powerpc-460-linux-gnu\usr\local\bin

     

    After adding these paths, you should be able to use bash.exe.

    Hi shansen

     

    thanks for the great tips.

    We are converging to a solution, but we still miss something.

     

    First, regarding the compilation under the Power Pmac Linux: this is the command that I need to issue to correctly compile with the ZMQ libs and gplib:

     

    gcc capp1.c -I/opt/ppmac/libppmac -I/opt/ppmac/rtpmac -L/usr/local/lib -L/usr/local/xenomai-2.5.6/lib -L/var/ftp/ppmaclibs/libppmac -lzmq -lrt -lpthread -lpthread_rt -lppmac

     

    I found all the path using the locate function on the linux: there are a lot of path containing the pthread_rt and ppmac libs, I picked up the most appealing path... if they are not the correct ones, please let us know.

    To correctly run the executable, I also need to set the $LD_LIBRARY_PATH variable according to the libraries path found above.

     

    Anyway, I make it work this way! Obviously, a solution that passes through the IDE and not through ftp + ssh + manual gcc + vim + anything that is needed to do that is very welcome.

     

     

    Let's go then to the discussion regarding the compilation under Windows.

     

    Here's a couple of clarification for who needs to do this job from the beginning:

    1- the correct path for the root dir on the windows pc is:

    C:\Program Files (x86)\Delta Tau Data Systems Inc\2.0\Power PMAC Suite\powerpc-460-linux-gnu

    2- the cygwin.bat file is not correct (or the installation went wrong): I don't have the system PATH environment variable to point to the cygwin dir. To use the cygwin and all the tools available under it, modify the cygwin.bat file adding the set PATH line as follows (or with your current bash / cygwin path):

     

    @echo off
set PATH=C:\Program Files (x86)\Delta Tau Data Systems Inc\2.0\Power PMAC Suite\powerpc-460-linux-gnu\bin;%PATH%
bash --login -i

     

    So, back to the real problem: I copied the libs and includes files in a dir under /usr/local/zmq, modified the makefile and then tried to compile, without success. I added in the makefile the "-L/usr/local/zmq -lzmq" and also a "-I/usr/local/zmq" to tell the compiler where to find the include files (not sure this -I is mandatory). Note that if I try to compile under the IDE and the Capp -L -l options correctly set, I got the same compilation errors, copied hereafter:

    These errors seems really strange to me, because it seems a linking problem to basic include files such string.h and so on.

    So, basically it seems that the compiler cannot reach include files that are however standards and installed on the system.

    Any ideas?

     

     

    Many many thanks

    Hi shansen

     

    thanks for the great tips.

    We are converging to a solution, but we still miss something.

     

    First, regarding the compilation under the Power Pmac Linux: this is the command that I need to issue to correctly compile with the ZMQ libs and gplib:

     

    gcc capp1.c -I/opt/ppmac/libppmac -I/opt/ppmac/rtpmac -L/usr/local/lib -L/usr/local/xenomai-2.5.6/lib -L/var/ftp/ppmaclibs/libppmac -lzmq -lrt -lpthread -lpthread_rt -lppmac

     

    I found all the path using the locate function on the linux: there are a lot of path containing the pthread_rt and ppmac libs, I picked up the most appealing path... if they are not the correct ones, please let us know.

    To correctly run the executable, I also need to set the $LD_LIBRARY_PATH variable according to the libraries path found above.

     

    Anyway, I make it work this way! Obviously, a solution that passes through the IDE and not through ftp + ssh + manual gcc + vim + anything that is needed to do that is very welcome.

     

     

    Let's go then to the discussion regarding the compilation under Windows.

     

    Here's a couple of clarification for who needs to do this job from the beginning:

    1- the correct path for the root dir on the windows pc is:

    C:\Program Files (x86)\Delta Tau Data Systems Inc\2.0\Power PMAC Suite\powerpc-460-linux-gnu

    2- the cygwin.bat file is not correct (or the installation went wrong): I don't have the system PATH environment variable to point to the cygwin dir. To use the cygwin and all the tools available under it, modify the cygwin.bat file adding the set PATH line as follows (or with your current bash / cygwin path):

     

    @echo off
set PATH=C:\Program Files (x86)\Delta Tau Data Systems Inc\2.0\Power PMAC Suite\powerpc-460-linux-gnu\bin;%PATH%
bash --login -i

     

    So, back to the real problem: I copied the libs and includes files in a dir under /usr/local/zmq, modified the makefile and then tried to compile, without success. I added in the makefile the "-L/usr/local/zmq -lzmq" and also a "-I/usr/local/zmq" to tell the compiler where to find the include files (not sure this -I is mandatory). Note that if I try to compile under the IDE and the Capp -L -l options correctly set, I got the same compilation errors, copied hereafter:

    These errors seems really strange to me, because it seems a linking problem to basic include files such string.h and so on. In fact, using the bash, I can issue a "make depend" to check dependencies, and what I got is the following (sorry for the layout, the copying from the shell is crappy):

    So, basically it seems that the compiler cannot reach include files that are however standards and installed on the system.

    Any ideas?

    Hi

    thanks for the clarification of the parser errors.

    Unfortunately, the code does not compile:

    [...]\GLT2.ppproj(168,5): Error : capp1.o: In function `main':
[...]\C Language\Background Programs\capp1capp1.c(64,0): Error :  undefined reference to `zmq_ctx_new' 
[...]\GLT2.ppproj(168,5): Error : collect2: ld returned 1 exit status
	Build Process For capp1.out has ended.

Done building project "GLT2.ppproj" -- FAILED.

     

    I think the compiler can not locate the ZMQ libraries, even if they are installed in /usr/local/lib . Do I have to specify some particular options to the GCC?

     

    (in this thread: http://forums.deltatau.com/showthread.php?tid=1705 I explained how I installed the ZMQ libraries on the Power PMAC and how I'd like to use them).

     

    EDIT:

    I found out how to compile with the ZMQ libraries.

    I downloaded the .c file on the PowerPMAC, connected in SSH and compiled with GCC. I had to use the options -L/usr/local/lib -lzmq to tell the compiler to use the specific libZMQ (it works even without the -L/usr/local/lib):

    gcc capp1.c -L/usr/local/lib -lzmq

    A major drawback of this approach is that the compiler can not find the gplib.h library; so for the moment I commented the gplib.h instructions InitLibrary() and CloseLibrary(). If I leave included the gplib.h, gcc replies this:

    capp1.c:1:56: error: gplib.h: No such file or directory

    Should I include the gplib.h with an explicit link? Where it is located? I tried to include any of the following:

    /opt/ppmac/libppmac/gplib.h
/opt/www/ppmac/libppmac/gplib.h
/var/ftp/ppmaclibs/libppmac/gplib.h
/var/ftp/www/ppmac/libppmac/gplib.h

    but it does not compile.

     

     

    I also tried to use these compiler option in the IDE, by setting the proper option in the "C App Property", without success.

     

    If I use the option -L/usr/local/lib -lzmq in the "Compile Option", I got the error 

    [...]GLT2.ppproj(171,5): Error : powerpc-405-linux-gnu-g++: -lzmq: linker input file unused because linking not done

    If I use the -L/usr/local/lib -lzmq in the Linker Option, I got this error message:

     

    [...]GLT2.ppproj(171,5): Error : /usr/local/bin/../lib/gcc/powerpc-405-linux-gnu/4.2.2/../../../../powerpc-405-linux-gnu/bin/ld: cannot find -lzmq
[...]GLT2.ppproj(171,5): Error : collect2: ld returned 1 exit status

    Any idea on how should I proceed?

    C++ background apps?

    Posted

    It looks like the errors are purely aesthetic, and have nothing to do with the compilation (e.g. the compile is succeeding). I think this is because the Delta Tau IDE is using a custom C language parser and it isn't great at recognizing and mapping all of the referenced include files.

    However, if the application compiles, then that means everything is working properly. Have you tried to download and run the application after compiling?

     

    ok, I understood that, in fact 2nd and 3rd figures show that the compilation is done. Unfortunately, the 1st figure shows the error on the first (only) call zmq_ctx_new(); to the library.

    However, if the application compiles, then that means everything is working properly. Have you tried to download and run the application after compiling?

     

    ok, I understood that, in fact 2nd and 3rd figures show that the compilation is done. Unfortunately, the 1st figure shows the error on the first (only) call zmq_ctx_new(); to the library.

    Why doesn't zeromq work with the IDE? What errors are you getting?

     

    I think you should be able to get this to work, but it may require manually editing the Makefile and adding a line to link your Capp against the compiled zeromq library.

     

    Another option is copying your Capp code to the Power PMAC and compiling it locally.

     

    I get 2 strange behaviors that I cannot understand. First of all, I installed the libraries, everything seems ok, I can see that the libzmq.a, .so, etc in /usr/local/lib and the .h in /usr/local/include

    When I load the zmq.h and zmq_utils.h in the IDE and include them in the main .c without using any function of the lib, the compilation is ok (see main.png). However, if I open the zmq.h file, the editor keeps telling me that there are a lot of syntax error (see syntaxerror.png), even if the file should be ansi C compliant.

     

    Then, if I try to use any of the functions inside the zmq.h, I get stopped by the syntax error in the zmq.h (compilation.png).

     

    So, basically, I really don't understand what is happening on the system.

    Could it be a compiler issue? Do you think I can get better results if I compile directly the file on the PMAC bypassing the IDE?

     

     

    thanks

    Hi shansen

    thanks for the insight. I asked this because I need to use special libraries (zeromq.org) that seems to not work inside the Deltatau IDE.

    I would prefer using the deltatau IDE, but I have some compatibility issues that I cannot (yet) sort out.

     

    Thanks a lot

    If you only need C applications, I would recommend Delta Tau's IDE. It is already set up with this capability, and it is much easier to use.

     

    That being said, my company has been using Eclipse instead of Delta Tau's IDE for several years now. Like anything, there are benefits and drawbacks to either method. Using Eclipse is not "easy" or "out-of-the-box" like Delta Tau's IDE. But, it does give us much more flexibility for organizing our projects, and allows us to compile any C or C++ code that can run on the Power PMAC.

    Hi shansen and all

     

    I am starting now to build for my first standalone C application for the PMAC. It this guide still true? Do you have any new hints or should I follow straightforward these steps?

     

    Many thanks for your guide!

    @MClement:

     

    I've just been using Eclipse CDT, in addition to the RSE plugin.

     

    Here is how my IDE is setup:

     

    1) Windows 7 with Eclipse CDT and MinGW installed

    2) My Eclipse projects are built using DT's cross-compiler (powerpc-405-linux-gnu-gcc/g++) and linked to the DT provided PPMAC libraries. NOTE: I did have to upgrade the version of 'make' (the version provided by DT isn't completely compatible with Eclipse for some reason)

    3) Eclipse automatically generates the makefiles as part of the build process

    4) RSE lets you create remote targets and build groups. For example, I have one build group that builds all of my projects and downloads them to the correct location on the PPMAC when finished.

    5) RSE also provides pretty convenient telnet terminal(s) for debugging + starting and stopping apps

    6) The Eclipse debugger CAN debug remotely, but it requires upgrading the PPMAC from Lenny to Squeeze (so you can install gdbserver on the PPMAC). I haven't taken it this far, but plan to do so in the future.

     

    If you have any specific questions, let me know. It took a little bit to get everything working, but it is almost completely seamless the way I have it set up now.

     

    As a side note, using Eclipse for PPMAC development is definitely not for everyone! For example, I cannot do motion programs or PLCs in Eclipse (I haven't tried it at least). However, Eclipse does let you create your own project structure, and the more advanced intellisense, auto-coloring, and refactoring support is great! Plus, you can build and download applications and libraries individually, which (last I checked) you cannot do with the vanilla DT IDE.

    Ethercat IO missing registers

    in Power PMAC

    Posted

    Hi all

    I have a problem configuring a small Ethercat IO network with a Power Brick LV.

    The ethercat devices connected to the PowerBrick are: (all beckhoff)

    - EK1100 (ethercat coupler)

    - 3x EL3204-0200 (4x RTD / PT1000 input)

     

    The Power PMAC System Setup recognizes the devices and I am able to read some registers, for example the 0x60n0:17 that are the analog RTD input. However, I need to configure some registers to make the EL3204 postprocess correctly the input (in fact the default readout is not the temperature). The configuration registers start from 0x8000, but I cannot access to them.

    I tried to load a proper XML configuration file (containing the definition of these registers) but the System Setup does not show them.

    I also tryed a manual readout of the registers via the command line, but I am still getting error messages ("Failed to read register: Input/output error").

     

    Am I missing something?

     

    -- EDIT:

    ok, I set the proper value to the register using the command DOWNLOAD:

    ethercat -m0 -p 1 -t uint16 0x8000 0x19 0

    where 0x8000 is my address, 0x19 the subindex and 0 the correct value.

    However, reg_write and reg_read still raise errors, and the System Setup tool is not able to recognize there addresses.

     

     

     

    thanks

    I don't know why it isn't working with the IDE, but I suspect there is a way to get it to work. I'm not much help in that department as I haven't used the IDE for several years. Maybe someone else can chime in about how to add a 3rd party library within the IDE.

     

    Regarding your second question, I know it is possible to use Mono to run C# apps on the Power PMAC, but I haven't done so myself.

    It looks like your install is failing because the file system is still mounted read-only. To mount it read/write, use:

     

    mount -o remount,rw /

     

    Then, install the library. When you're done, mount the file system as read-only again:

     

    mount -o remount,ro /

     

    it works, thanks a lot!

     

    Unfortunately, the include files zmq.h is not working with the IDE. I can't understand that problem because it should be an ANSI C source code...

     

    However, I read on the forum (here for example http://forums.deltatau.com/showthread.php?tid=910 ) that it is possible to write C / C++ code with external tools, using the deltatau libs for the access to the PMAC variables; or using even C# with the mono libs ( http://forums.deltatau.com/showthread.php?tid=166 ).

    I would go then with the mono + C# for my solution.

     

    Do you think I have any chances to make it work?

     

    thanks
