Communication with external word

[piefum]

Hi all

has anyone tried the zeromq libraries ( http://zeromq.org/ ) on the Power PMAC system?

I will need this solution to implement a socket communication mechanism between my Power PMAC and a global Control System for the entire plant.

Do you think these libraries can be imported on the Pmac IDE and compiled for the PowerPMAC?

 

thanks

I just downloaded zmq and compiled it on the Power PMAC without issue. Also, the test examples seemed to be running correctly.

 

However, I am not sure if it is supported through the IDE.

Hi

how did you manage to install the zeromq libraries on the pmac?

 

I copied all the sources on /tmp, run "./configure" and "make" and everything worked fine; however, I get a write-only error:

 

:/tmp/zeromq-4.0.4# make install
Making install in src
make[1]: Entering directory `/tmp/zeromq-4.0.4/src'
make[2]: Entering directory `/tmp/zeromq-4.0.4/src'
test -z "/usr/local/lib" || /bin/mkdir -p "/usr/local/lib"
/bin/sh ../libtool   --mode=install /usr/bin/install -c   libzmq.la '/usr/local/lib'
libtool: install: /usr/bin/install -c .libs/libzmq.so.3.1.0 /usr/local/lib/libzmq.so.3.1.0

make[1]: *** [install-am] Error 2
make[1]: Leaving directory `/tmp/zeromq-4.0.4/src'

how can I install the libraries?

 

thanks

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

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.
