Communication with external word

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

gigi

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
/usr/bin/install: cannot create regular file `/usr/local/lib/libzmq.so.3.1.0': Read-only file system
make[2]: *** [install-libLTLIBRARIES] Error 1

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

 

how can I install the libraries?

 

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.

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

gigi

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.
