When i emerge crypto++ 5.2 i get a lot of error after having compiled a lot of files, i dont know it is g++ or crypto++ but the errors told me that it was the compiler. i have attached the Preprocessed source that emerge gave me. Reproducible: Always Steps to Reproduce: 1. just do emerge crypto++ Actual Results: about 40 files were compiled but i got a warning and then an error from the compiler g++ -march=pentium4 -O2 -pipe -fomit-frame-pointer -c ida.cpp g++ -march=pentium4 -O2 -pipe -fomit-frame-pointer -c idea.cpp Dans le fichier inclus

i cant attach the Preprocessed source because the file is empty :| the first time i compiled crypto++ the file was not.
Created attachment 40051 [details, diff] Patch to ebuild Looks like another gcc 3.4 sse2 issue. I added a check to see if you are using gcc 3.4 and if so, it replaces march=pentium4 with mtune=pentium4, which allows it to compile.
rather append -mno-sse2 copy what we did in xorg 6.8 we cant apply -mno-sse2 for all archs but using the test assures it only gets applied if the arch supports -mno-sse2 (we need to make sure pentium-m is taken care off too, and this way you get the rest of -march= w/o the (currently) problematic sse2 ill apply this then tomorrow if sekretarz or robmoss dont get to it before me thanks for tracking it down to sse2
Yea, didn't think of doing it that way. That's a much better way :)
So, i tried with -mno-sse2, it worked, it compiled, but the tests failed after :) i have seen the bug report about that other problem, looks like it's -fomit-frame-pointer. Why dont you remove it too in the ebuild like you do with -O3 and now -mno-sse2 ? Thx for your help
