  To: xenomai

Hello all,

We use xenomai 2.6.2.1 with g++ 4.7.2 from buildroot on a Armadeus apf27
board. This works really fine, but if we add "-W -Werror -Wall -pedantic
-pedantic-errors" in compiler command line, g++ detects some warnings for
a code as simple as :

#include <native/task.h>
int main() {
     return 0;
}

The complete log of the compilation is attached with this email.

The compiler complains about various things, in differents files. I have 
not
tested other xenomai's headers like native/queue.h, etc. yet.

Do you have any plans to fix them?

Best regards,
Victor Hiairrassary

What you could do to fix them is to move the functions implemented in
trace.h to an src/skins/common/trace.c, this would allow to remove
asm/xenomai/syscall.h from nucleus/trace.h, and would solve most of the
warnings you are showing us. When you are done and it works for you,
please submit a patch.

As for the variadic macros, I believe they exist in C99, so perhaps you
are not compiling with the right flag, or perhaps we do not use the C99
syntax, which probably could be fixed too.

It is a bit more complicated than that, removing asm/syscall.h from
nucleus headers breaks __xn_rdtsc for instance. We will keep this change
for later.

Hi Victor,

I have tried and fix this issue in Xenomai repository
(git://xenomai.org/xenomai-2.6.git), the errors disappeared completely
for the native and posix skins headers in C. The modifications made to
the posix headers for C do not seem to work for C++. It would be
interesting if you could download and try it.

Without "-pedantic-errors", including posix headers in a C++ program
simply triggers warning.

Regards.

Hello,

I have tried with these settings (board apf27 : arm imx27):

xenomai_ver = f60f1a4f758a7d9b010f39f439eb98240b7beb42
xenomai_site = git://git.xenomai.org/xenomai-2.6.git
buildroot: 2013.02
gcc: 4.7.2
libc: eglibc 2_12
busybox: 1.21.0
U-Boot: custom (2012.04)
Linux: 2.6.38.8

I have tested a simple program (available in attached file compiler
command lines and logs) in c90, c99, c++03 and c++11 standard.

Only c++11 have no warning !

Do not hesitate if you have other questions !

Best regards,
Victor Hiairrassary

===============
    toolchain/bin/arm-linux-g++ main.c -I toolchain/include/xenomai -o m -W -Wall -pedantic -std=c++11

    No error at all in c++11 :D

You do not see the posix warnings because you are not compiling with
posix skin flags (xeno-config --skin posix --cflags)
c99 does not work for you for the same reason (you are not using the
flags provided by xeno-config).
I am not going to fix things more than that, I do not see why anyone
would want to compile with old standards like c90 or c++03
Regards.
