On my 2.4 kernel system, when emerging svgalib I end up building an svgalib_helper.o module with unresolved systems. This appears to be due to the ebuild using Makefile.alt to build the module. Commenting out the kernel detection like so: if ! use build && kernel-mod_modules_supported ; then cd "${S}"/kernel/svgalib_helper # if [[ `KV_to_int ${KV}` -lt `KV_to_int 2.6.6` ]] ; then # env -u ARCH \ # make -f Makefile.alt INCLUDEDIR="${ROOT}/usr/src/linux/include" \ # clean modules || die "Failed to build kernel module!" # else env -u ARCH make || die "Failed to build kernel module!" # fi cd "${S}" fi allows a working module to be built. It appears that the alternative makefile should be used for 2.6 kernels before 2.6.6, but not 2.4 kernels (or at least not my 2.4 kernels). In which case the kernel version detection here should be altered. Reproducible: Always Steps to Reproduce: 1.Use 2.4 kernel 2.Emerge svgalib 3.Run depmod Actual Results: Depmod shows there are unresolved symbols in svgalib_helper.o, and attempting to modprobe it produces a long list of unresolved symbol errors Expected Results: Depmod should give no output, and modprobe svgalib_helper should work without error, as it does after emerging with the kernel detection commented out as above.

what does /usr/src/linux point to ?
