It appears that openmpi has some troubles with the following CFLAGS: --param l1-cache-size=64, --param l2-cache-size=512.
After removing this two flags, it compiles correctly. |

I had the same problem, not being able to install any of the openmpi packages available. I have tried screwing around with various settings, gcc versions, etc, but nothing worked.
Finally, I found out I was using wrong/outdated CFLAGS, for older versions of gcc. I have an intel core-i7 2620M, and used:
| Code: | | CFLAGS="-O2 -pipe -fomit-frame-pointer -march=core2 -maes -mpclmul -mpopcnt -mavx --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=4096 -mtune=generic" |
when I should be using:
| Code: | | CFLAGS="-O2 -pipe -fomit-frame-pointer -march=corei7-avx -mno-movbe -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mno-avx2 -mno-lzcnt --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=4096 -mtune=corei7-avx" |
whether or not these flags are now optimized, openmpi-1.6.4 emerged without any errors, without removing the l1/l2-cache-size params.
Do note, however, that I still have problems with openmpi, with compilation hanging indefinitely (dev-libs/boost), but I believe it's unrelated to this issue. |
