This should not happen, header file should not depend on the inclusion order. > > - User-space satch: It was necessary to move "#define xnprintf printf" > behind the include block, otherwise the linker complains about missing > symbols.

I had to make the printf change (xnprintf is now defined in xenomai include files to xnarch_printf, but xnarch_printf is not defined when compiling in user space, so I replaced #define xnprintf printf with #define xnarch_printf printf) to make it work again, but I saw no problem with include file order. > > - I got the module build, but insmod fails with: > > bash-2.05b# insmod satch.o > satch.o: unresolved symbol shm_unlink > satch.o: unresolved symbol ftruncate > satch.o: unresolved symbol shm_open > satch.o: unresolved symbol munmap > satch.o: unresolved symbol mmap > satch.o: unresolved symbol pse51_shm_close > > Any idea why?
