This still isn't perfect. When the common/xbps-src/shutils/chroot.sh function chroot_init() is called, the value for $XBPS_FFLAGS, which is defined in common/build-profiles/bootstrap.sh, is empty. Put the immediate value into the generated /etc/xbps/xbps-src.conf file until someone finds out where passing the value of $XBPS_FFLAGS throughout the scripts is missing.
BUILD PROFILES ============== This directory contains build profiles to set properties on native builds for a specific architecture: - XBPS_TRIPLET (the compiler triplet) - XBPS_CFLAGS (C compiler flags for host compiler) - XBPS_CXXFLAGS (C++ compiler flags for the host compiler) - XBPS_FFLAGS (Fortran compiler flags for the host compiler)
