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 * * ERROR: x11-drivers/nvidia-drivers-173.14.09 failed. * Call stack: * ebuild.sh, line 49: Called src_compile * environment, line 3654: Called linux-mod_src_compile * environment, line 2688: Called die * The specific snippet of code: * eval "emake HOSTCC="$(tc-getBUILD_CC)" CROSS_COMPILE=${CHOST}- LDFLAGS="$(get_abi_LDFLAGS)" ${BUILD_FIXES} ${BUILD_PARAMS} ${BUILD_TARGETS} " || die "Unable to emake HOSTCC="$(tc-getBUILD_CC)" CROSS_COMPILE=${CHOST}- LDFLAGS="$(get_abi_LDFLAGS)" ${BUILD_FIXES} ${BUILD_PARAMS} ${BUILD_TARGETS}"; * The die message: * Unable to emake HOSTCC=i686-pc-linux-gnu-gcc CROSS_COMPILE=i686-pc-linux-gnu- LDFLAGS= IGNORE_CC_MISMATCH=yes V=1 SYSSRC=/usr/src/linux SYSOUT=/lib/modules/2.6.25-gentoo-r9/build HOST_CC=i686-pc-linux-gnu-gcc clean module * * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/x11-drivers/nvidia-drivers-173.14.09/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/x11-drivers/nvidia-drivers-173.14.09/temp/environment'. * I also tried nvidia-drivers-177.80 but it fails with same message Reproducible: Always xblade linux #
