The issue with exam37 seems to be fixed in the latest gcc (4.7.2), but I'm not sure if the workaround should be taken out. One reason to do so would be to encourage the usage of newer gcc since there are many other bugs fixed also.

If compiled with gcc-4.8.2 or gcc-4.9.0 gamess fails all the tests. It is possible to tweak the optimization levels so all the tests still pass but it gets very slow, since the files that perform intensive computations have to be compiled using -O0 It is better to use dragonegg/llvm - it passes all the tests. I use it by creating /etc/portage/env/sci-chemistry/gamess file with the follwing content: FFLAGS="-O2 -pipe -march=corei7 -fplugin=dragonegg.so" Just my 2c :-) (In reply to milan hodoscek from comment #3) > If compiled with gcc-4.8.2 or gcc-4.9.0 gamess fails all the tests. This is known issue - look at http://blog.regehr.org/archives/918 I will be better to add "-fno-aggressive-loop-optimizations" into ebuild. There is a new version of gamess: 20141205.1 This one already includes -fno-aggressive-loop-optimizations in the comp script Anybody working on a new ebuild ? I made a very restrictive ebuild (gcc-4.9 or gcc-4.8 only, no tinker, etc) |
