[Description jINKs 2003-02-01 11:19:40 UTC]

when i try to emerge transcode (0.6.3.20030116) the make process stops with the following error:

scale down your optimisation settings and test please

[Comment 3 Diego Palacios 2003-02-02 13:14:10 UTC]

I had the same problem, maybe most updated version of transcode would have to 
be unmasked to resolv the problem 

[Comment 4 Seemant Kulleen (RETIRED) 2003-02-05 14:44:13 UTC]

take out the ffast-math flag and try again, please -- this error is a result of your optimisation settings.

[Comment 5 phoen][x 2003-02-07 12:59:00 UTC]

Are you absolutely sure, seemant?

[Comment 6 jINKs 2003-02-07 17:58:22 UTC]

I had not activated -ffast-math but it must be one of these:
-fomit-frame-pointer -mfpmath=sse -funroll-loops -falign-functions=4 -frerun-cse-after-loop -frerun-loop-opt

setting CFLAGS to these more conservative flags actually works:
-march=pentium3 -O3 -pipe -mmmx -msse

(I tried this once before without success... must have forgotten to rerun configure or so.)

[Comment 7 phoen][x 2003-02-13 14:40:24 UTC]

Its the "-mfpmath=sse". I'll modify the ebuild to always drop that option.

Works,

closing this bug as RESO FIXED.
