Hello comedi hackers! I recently started using comedi and so far the experience has been very pleasant. comedi is a great and greatly needed project. Thank you very much for your work! I'll now report some problems and tentative fixes for building comedi against a 2.6.15.2 kernel patched with hal-linux-2.6.15-i386-1.2-00.patch from rtai-3.3 with RTAI support. I used --enable-kbuild because otherwise the linux/include/asm-i386/mach-default/ directory was not included otherwise. I encountered two problems: 1) the include flags needed for RTAI are not passed to kbuild. The patch below tries to fix this for RTAI and RTLINUX, but as I'm not familiar with the build system I don't know if the fix is correct or complete. 2) In the file comedi/drivers/addi-data/addi_common.c the linux header asm/i387.h is included before linux/comedidev.h, which in turn includes RTAI headers that redefine "init_fpu" among others. This lead to errors which were resolved by moving the i387.h include before the comedidev.h include. As I'm don't understand the init_fpu macros of RTAI I don't know if this fix is correct, but it resolves my build problems. (I'm not going to use addi-data.)
