dependency, it is impossible to emerge anything afterwards because pyblake2 keeps hitting this illegal opcode problem. This is a typical system log entry:- Jan 4 21:57:36 newton3 kernel: traps: emerge[12441] trap invalid opcode ip:7f23eeec6815 sp:7ffd4c4edb68 error:0 in pyblake2.so[7f23eeec3000+8000] I have had to unmerge and mask all pyblake2 versions and revert portage to version 2.3.8 in order to restore the ability to install packages. This is probably cause NOT to mark amd64 as stable.
emerge --info indicates you are running a Pentium D, not a Core 2. Please try compiling with -march=nocona instead.
To elaborate, Core 2 supports the SSSE3 instruction set. Pentium D does not. pyblake2 uses SSSE3 instructions heavily if the compiler options allow it. GCC manual for reference: https://gcc.gnu.org/onlinedocs/gcc-6.4.0/gcc/x86-Options.html#x86-Options
Thanks for the steer, Mike. I have tried the change you suggest and all seems well now. My mistake for the Pentium D/Core 2 - it was set this way a long time ago and I cannot remember why! I'll try recompiling everything now and hopefully there will be no snags.
Closing as wrong CFLAGS then.
