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.
That's user-space stuff, in /usr/include/bits/sched.h on my box. Maybe
some #ifndef __cpu_set_t_defined + local definition is required here.
What glibc version do you use?
Ah, OK. The problem is with gcc version 3.3.3 (DENX ELDK 3.1.1 3.3.3-9),
which does not have cpu_set_t, indeed. The configure script already
deals with different implementations of setaffinity. The attached patch
fixes the problem. It removes CONFIG_SMP, which is not known to user
space applications anyhow. Well, it might get defined in
"src/include/xeno_config.h" somehow but I don't know how this could work
properly without knowing the configured kernel tree.
Wolfgang,
