use some sane build flags. --param is known to cause random issues. CXXFLAGS="-O2 -pipe -march=core2 -mcx16 -msahf -mpopcnt -msse4.2 --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=256 -mtune=core2"
Yeah, I've missed that. I've upgraded glibc and forgot about changed flags. I've changed cflags and it builds correctly, thanks.
So can this be closed? There doesn't seem to be anything that could be changed in Audacity to fix this, as the flags from the environment are being passed through correctly (as I understand it) to g++.
Closing as invalid.
