Now, the tarball generated at linuxtv.org site will have everything needed. However: The UABI patches deadly-broke our out-of-tree building system. One of the premises there is that there will be just one file with the same inside the entire media tree. It was never a problem before to do it, as it is not allowed to have two drivers for the same thing. The UABI patches did something weird, though: for some files, there are now _two_versions_ of the same API file, e. g. (from linux/Makefile): # Both Kernelspace and Userspace API TARDIR += include/linux/dvb/ include/uapi/linux/dvb/ TARFILES += include/linux/usb/video.h include/uapi/linux/dvb/video.h TARFILES += include/media/v4l2-subdev.h include/uapi/linux/v4l2-subdev.h TARFILES += include/media/v4l2-common.h include/uapi/linux/v4l2-common.h TARFILES += include/media/v4l2-mediabus.h include/uapi/linux/v4l2-mediabus.h Basically, all headers that used to have if __KERNEL__ inside were now converted into two files, one with the "kernel" header, and another one with the pure userspace version. That violates the previous rule imposed by the out-of-tree building system. Fixing it is not a trivial task, as it requires to replace this part of v4l/Makefile to something more smart: links:: @echo creating symbolic links... @find ../linux/drivers/media -name '*.[ch]' -type f -print0 | xargs -0n 255 ln -sf --target-directory=. @find ../linux/sound -name '*.[ch]' -type f -print0 | xargs -0n 255 ln -sf --target-directory=. @find ../linux/drivers/staging -name '*.[ch]' -type f -print0 | xargs -0n 255 ln -sf --target-directory=. @find ../linux/drivers/misc -name '*.[ch]' -type f -print0 | xargs -0n 255 ln -sf --target-directory=. So that would, for example, detect those duplicated files and select just the Kernel one, and add a "-I ../linux/include", in order to allow those includes to get the *uapi/* one. Another alternative would be to not create links for *.h at all. The build system logic could also be completely replaced by one that works with subdirs. Not sure what's the better one (and probably won't have any time to actually write such patches anytime soon). So, suggestions, patches, etc are very welcome. Hans, If we're unable to fix it soon, I suggest to disable the daily build report, or to remove the compilations from the media-build.git tree, as they'll all show ERRORS.
