[Xenomai-help] Error at compilation of examples

[Benoît CAMUS]

Hi all,

I got errors in headers while trying to compile basical programs
(sigcpu.c and a posix thread one). I use ELDK 4.1 cross-compiler for ARM
architecture and 2.6.19 kernel. So here is error i got:


$> arm-linux-gcc -I/opt/eldk/arm/usr/include/ -I/opt/eldk/arm/include/
-D_GNU_SOURCE -D_REENTRANT -L/opt/eldk/arm/lib/ -lpthread -lnative
-Xlinker -rpath -Xlinker /opt/eldk/arm/lib/ -o t_posix ./test_thread.c

In file included from /opt/eldk/arm/include/nucleus/queue.h:24,
                 from /opt/eldk/arm/include/nucleus/timer.h:23,
                 from /opt/eldk/arm/include/nucleus/thread.h:23,
                 from /opt/eldk/arm/include/posix/pthread.h:149,
                 from ./test_thread.c:1:
/opt/eldk/arm/include/nucleus/types.h:75: error: parse error before
'xnflags_t'
/opt/eldk/arm/include/nucleus/types.h:75: warning: data definition has
no type or storage class

Is there something i missed in xenomai's configuration ?

That's parameters i put:
configure --prefix=/ --build=i686-linux-gnu --host=arm-linux
--enable-arm-arch=4 --disable-dox-doc --disable-dbx
--disable-dbx-network --disable-x86-tsc

Thanks,
Benoit

The most simple way to compile an example for Xenomai posix skin is to
use the xeno-config script as installed by Xenomai. If you have run
Xenomai installation with DESTDIR set, pass the same DESTDIR in
xeno-config environment. Examples usually come with Makefiles that do so.

What version of Xenomai are you using ?

I'm using xenomai last version (2.3.1), 
and have the same error using makefile with XENO parameter

I just tried compiling the examples and found two reasons why it might
not compile:
- the patched Linux kernel sources must have been compiled (so that the
include/asm symlink is created)
- if you are cross-compiling, you must pass the proper ARCH variable at
make invocation for compiling the kernel modules.

The last problem I have is the link order, but to solve this, I guess
the Makefiles should be changed.

Here is what I get:

IMHO, the command line should be:
gcc -m32 -I/usr/xenomai-2.3.1/include -D_GNU_SOURCE -D_REENTRANT
cross-link.c  -L/usr/xenomai-2.3.1/lib -lpthread  -lnative -lrtdm
