!!! ERROR: media-libs/svgalib-1.9.17-r1 failed.
!!! Function src_compile, Line 77, Exitcode 2
!!! Failed to build kernel module!


Reproducible: Always
Steps to Reproduce:
1.  emerge svgalib-1.9.17-r1
2.
3.

Actual Results:  
See [Details]

Expected Results:  
Installed correctly :)

Note that awk also throws an error about the /usr/src/linux being a directory,
which is actually a symlink to linux-2.5.69.

same results with my system under 2.5.70-mm3 kernel

Same result for me under development-sources-2.5.70 and gcc3.3
Also a similiar result for svgalib-1.9.16 (Line 48 and src_install, but same errors before, ...)

fails to compile under 2.5.72 alos :(((

az - seems like you fixed it once... want to look @ it again?

This is still a big issue, esp when installing on new machines and using any
2.6.x kernel.

Please increase priority :)

Erik

svgalib-1.9.17-r2 fails too because he wants 
/usr/src/linux/includes/linux/modversions.h and this does not exist there in 2.4 and 
is in config/modversions.h in 2.5/6 

Ok, here is the story:

 1) It will only work with 2.4 and 2.6 kernels, and _not_ 2.5 kernels.
    2.5 is in the past, get over it 8)

 2) You need a kernel with module support, which thus have a modversions.h
    header:

---------------------------------------------------------------------------
azarah@nosferatu azarah $ ls /usr/src/linux-2.4.20/include/linux/modversions.h
/usr/src/linux-2.4.20/include/linux/modversions.h
azarah@nosferatu azarah $
---------------------------------------------------------------------------

 3) You will only have a version.h, modversion.h, etc _temporary_ headers if
    you run 'make dep' in 2.4 kernels, and for 2.6 - err, start the compile
    for a while :/

Questions ? :)

Anyhow, should be fixed for 2.4/2.6 kernels.

No, it is not fixed as far as I can see. 
I just tried to compile svgalib-1.9.17-r2 against mm-sources (2.6.0-test2-mm4) and it can still not find modversions.h. The reason is that it looks for it in the wrong place:

Here is a typical example:
gcc -O2 -DLINUX -Dlinux -D__KERNEL__ -DMODULE  -nostdinc -iwithprefix include -DKBUILD_MODNAME="svgalib_helper" -I/var/tmp/portage/svgalib-1.9.17-r2/work/svgalib-1.9.17/kernel/svgalib_helper/include -I. -I/lib/modules/2.6.0-test2-mm4/build/include -I/lib/modules/2.6.0-test2-mm4/build/include/asm/mach-default -DSVGALIB_HELPER_MAJOR=209 -DMODVERSIONS -include /lib/modules/2.6.0-test2-mm4/build/include/linux/modversions.h -M *.c > .depend

Now the file, modversions.h, is located here:
/usr/src/linux-2.6.0-test2-mm4/include/config/modversions.h

Hence the problem is not solved and it still requires manual intervention in order to get it to build.

The header file does not exist under /lib/modules/2.6.0-test2-mm4 either and I do use modules as the output of lsmod shows:
Module                  Size  Used by
snd_pcm_oss            58148  0
snd_pcm               108192  1 snd_pcm_oss
snd_page_alloc         16388  1 snd_pcm
snd_timer              31620  1 snd_pcm
snd_mixer_oss          23680  1 snd_pcm_oss
snd                    59620  4 snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss

Bleh, sorry guys - I did try to test as best possible, but I forgot that my
2.5/6 kernels do not have CONFIG_MODVERSIONS set anymore.  Should really be
fixed in -r3 =)
