Hello,

I have some problems to compile my code Posix for ARM. I have installed
xenomai in /usr/xenomai_arm-2.3.1 for ARM.

Here is my compilation :


[root@domain.hid Essai_mutex_arm]# make XENO_CONFIG=/usr/xenomai_arm-2.3.1

It would seem the problem is only with Posix.

In the directory /usr/xenomai_arm-2.3.1/lib, I have only static librairies
(.a, .la). Maybe it's the problem.

The order of arguments on the linker command line is important, this
should be:

essai_mutex_rt.o -lpthread_rt -lpthread -lrt

[Daniel Schnell]

Or you place somewhere before the linker option

-Wl,--start-group

to tell the linker to iterate several times over the library interdependencies.

Even if gcc doc says different, you actually do not need a -Wl,--end-group option.



Best regards,

Daniel Schnell.

Thanks a lot, it works fine.
I did this : essai_mutex_rt.o -lpthread_rt -lpthread -lrt   in the linker
command line.
