[Xenomai-help] CONFIG_XENO_OPT_SYS_STACKPOOLSZ warning

[Laurent BESSARD]

Hello all,

Recently, I tried to compile a driver for Xenomai and I received this 
warning while trying to include rtdm_driver.h:
In file included from /usr/xenomai/include/nucleus/xenomai.h:25,
                 from /usr/xenomai/include/rtdm/rtdm_driver.h:37
/usr/xenomai/include/nucleus/heap.h:110:5: warning: 
"CONFIG_XENO_OPT_SYS_STACKPOOLSZ" is not defined

This symbol is provided by kernel config while compiling kernel, but 
doesn't exist in any other context.

It would solve the problem if heap.h test if this symbol exist before 
trying to use it, or define a default value for this symbol like:

#ifndef CONFIG_XENO_OPT_SYS_STACKPOOLSZ
#define CONFIG_XENO_OPT_SYS_STACKPOOLSZ 0
#endif

Thanks,

Laurent

If you do not use the Linux kernel makefiles to compile your driver,
then it is your driver that is broken and needs fixing.
