[zeromq-dev] Cross-compiling zmq for PowerPC-405

[Crum, Gary A. (GSFC-5870)]

Tergeist, 
What SDK and Board are you using?

I'm using ELDK 4.2.  This was released in 2008.  ELDK 4.2 is using gcc 4.2.2 (built using crosstool-devel 0.43-3)

You might want to consider giving ELDK a try, it should work with most (all?) powerpc's.

thanks,
Gary

Hi,

I don't think my SDK is old. In fact, the SDK was with my box (Linux 2.6.10) and I received this box in June...

Otherwise, I check with the make V=1 and the flag -DZMQ_FORCE_POLL was passed to the build for all C end C++
source files...

So, dou you have some ideas about my epoll errors?

Thanks a lot for your answers.

Tergeist P.

I think the problem is that even with ZMQ_FORCE_POLL the epoll symbols
are still compiled in (the epoll.cpp check is for ZMQ_HAVE_LINUX).

The --with-poller makes choosing the system easier but in addition to
this f716b571baf59c1b622c7666bb8bf2905126a3d4 is needed from libzmq
master to prevent additional polling systems from being compiled in.
In addition to this probably would make sense to change the build
system to only build the polling system chosen (currently empty
objects are created for the disabled ones).
