The configure script has a --enable-smp option that set CONFIG_SMP in xeno_config.h. sched_setaffinity is unneeded when not running over SMP machine, so I thought it would be simpler to completely avoid sched_setaffinity over UP machines. The proper fix is to also define cpu_set_t when CONFIG_SMP is not set. I will fix this. -- Gilles Chanteperdrix. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core

[Xenomai-core] cpu_set_t and friends undefined
Hello, with todays SVN version of Xenomai, the testsuite program switchtest/switch.c does not compile because cpu_set_t and friends (CPU_SET, ...) are not undefined. I'm using kernel version 2.4.25. Any idea what goes wrong. I haven't found where cpu_set_t is declared, not even in Linux 2.4.17.7. Thanks.
