The su nobody command also prohibits builds from working when using a custom kernel:
m...@zest:/var/lib/dkms/nvidia/185.18.36/build$ sudo su nobody -c "make KERNELRELEASE=2.6.31.3-bfs303 module KERNDIR=/lib/modules/2.6.31.3-bfs303 IGNORE_XEN_PRESENCE=1 IGNORE_CC_MISMATCH=1 SYSSRC=/lib/modules/2.6.31.3-bfs303/build" If you are using a Linux 2.4 kernel, please make sure you either have configured kernel sources matching your kernel or the correct set of kernel headers installed on your system. If you are using a Linux 2.6 kernel, please make sure you have configured kernel sources matching your kernel installed on your system. If you specified a separate output directory using either the "KBUILD_OUTPUT" or the "O" KBUILD parameter, make sure to specify this directory with the SYSOUT environment variable or with the equivalent nvidia-installer command line option. Depending on where and how the kernel sources (or the kernel headers) were installed, you may need to specify their location with the SYSSRC environment variable or the equivalent nvidia-installer command line option. *** Unable to determine the target kernel version. *** make: *** [select_makefile] Error 1 m...@zest:/var/lib/dkms/nvidia/185.18.36/build$ vs: m...@zest:/var/lib/dkms/nvidia/185.18.36/build$ sudo make KERNELRELEASE=2.6.31.3-bfs303 module KERNDIR=/lib/modules/2.6.31.3-bfs303 IGNORE_XEN_PRESENCE=1 IGNORE_CC_MISMATCH=1 SYSSRC=/lib/modules/2.6.31.3-bfs303/build NVIDIA: calling KBUILD... make CC=cc KBUILD_VERBOSE=1 -C /lib/modules/2.6.31.3-bfs303/build SUBDIRS= modules make -f /home/mbt/Projects/git/linux-2.6.31.y/Makefile silentoldconfig make -f scripts/Makefile.build obj=scripts/basic gcc -Wp,-MD,scripts/basic/.fixdep.d -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/basic/fixdep scripts/basic/fixdep.c ... Using a different account for building dkms modules is understandable, but if it's going to do that, it should do sanity checking first and ensure that it can access things that way. If it cannot it should either not use su at all, or it should copy the kernel source symlink target to a location it can use, and build against that tree, then remove the tree when its done. -- DKMS module fails to build if CC env-var set but not OK (=> "sudo -H"?) https://bugs.launchpad.net/bugs/438393 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
