Hi folks, I detected a minor problem while compiling 2.6.14.2 with the most recent xenomai code from svn. The Compilation would quit at linking if one tries to build the posix skin as built-in module. Abort message:
ipc/built-in.o: In function `sem_init': : multiple definition of `sem_init' kernel/built-in.o:: first defined here ld: Warning: size of symbol `sem_init' changed from 296 in kernel/built-in.o to 55 in ipc/built-in.o The problem is the sem_init() method of the SysV IPC routine in the linux kernel, which is unluckily called excactly the same as the posix sem_init() but differently declared. It's declared as void __init sem_init (void) in SysV IPC and int sem_init(sem_t *sem, int pshared, unsigned value); in POSIX. Thus the linker get confused trying to link the two symbols in one kernel image. Workaround coulb be deactivating the SysV IPC routine in the kernel or compile Posix skin as a loadable module.
