Hi Claudio,

Ok it is working Now :-)

I changed the BUILD_DIR from your makefile :

             CFLAGS="$(TARGET_CFLAGS) 
-I/home/fox/trunk/build_dir/linux-etrax/linux-2.6.19.2/include"

and I get other errors :
error: expected declaration specifiers or '...' before 'gpiosetbits'

Then I started to change the #include <asm/unistd.h> in the 
gpio_syscalls.h file
and sometimes the errors changed to :
error: '__NR_gpiosetbits' undeclared (first use in this function)

So finally I leave the default #include <asm/unistd.h>
and I add #include <asm-cris/arch-v32/unistd.h>
this hack solve the problem.

Thank you Claudio for your help.

Regards,

Frederic.
