Bug 66180 – meida-libs/glide-v3 (3.10-r4) missing -lm

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Dr. David Alan Gilbert 2004-10-02 18:11:35 UTC]

On Alpha trying to build the glide package I hit the following error:
(I've had glide working on Alpha many years ago on Debian; I have a Voodoo 3 3000 PCI card).

make[3]: Entering directory `/var/tmp/portage/glide-v3-3.10-r4/work/glide3x/build/swlibs/texus2/cmd'
/bin/sh ../../../libtool --mode=link gcc  -O6 -m486          -o texus  cmd.o ../../../swlibs/fxmisc/libfxmisc.la                        ../../../swlibs/texus2/lib/libtexus.la
gcc -O6 -m486 -o texus cmd.o  ../../../swlibs/fxmisc/.libs/libfxmisc.a ../../../swlibs/texus2/lib/.libs/libtexus.a
../../../swlibs/texus2/lib/.libs/libtexus.a(eigen.o)(.text+0x47c): In function `eigenVectors':
: undefined reference to `sqrt'
../../../swlibs/texus2/lib/.libs/libtexus.a(eigen.o)(.text+0x488): In function `eigenVectors':
: undefined reference to `sqrt'

A -lm lets this link, but I don't know automake/autoconf to know where to stuff one in.
Note also that it is passing the -m486 which fortunately the compiler seems to be ignoring.

I suspect on x86 that there is some handcoded assembler and hence no need for the library sqrt() - but I don't know that for sure.

Reproducible: Always
Steps to Reproduce:
1. emerge of glide-v3

Actual Results:  
gcc -O6 -m486 -o texus cmd.o  ../../../swlibs/fxmisc/.libs/libfxmisc.a
../../../swlibs/texus2/lib/.libs/libtexus.a
../../../swlibs/texus2/lib/.libs/libtexus.a(eigen.o)(.text+0x47c): In function
`eigenVectors':
: undefined reference to `sqrt'

Expected Results:  
linked!

[PATCH] Add a -lm

Well this seems to get me past this error - I'm not sure how many similar ones
there are or whether this is the right way to do it - should probably check it
doesn't break x86.

[Comment 2 Thomas Cort (RETIRED) 2006-02-17 17:43:22 UTC]

There is a new version of glide-v3 in portage, glide-v3-20060203. Do you still get compile problems with the new version?

[Comment 3 Fernando J. Pereda (RETIRED) 2006-02-20 10:03:30 UTC]

Does version compiles flawlessly here. Haven't tested the driver though.

Reopen if it doesn't work.

Cheers,
