Correct. Compiler but not ports e.g., # excerpt from math/fftw3 . if !empty(MACHINE_CPU:Mavx) CONFIGURE_ARGS+=3D--enable-avx . endif > But since even the host failing the build does build the ports > properly in poudriere, doesn't reveal much I guess. By homework I've meant replicating live system environment bit-by-bit until= it can be reproduced within poudriere. This is a very tedious process but allo= ws to track down practically any bug except those affecting kernel or hardware. Another name to call it is bisecting environment. --=20 You are receiving this mail because: You are the assignee for the bug.=
