I used (extracted examples): CXX=3D g++9 -v -std=3Dc++17 -Wno-psabi -nostdinc -nostdinc++ -I/usr/include/c++/v1 -I/usr/include and for use in linking: LDCXX=3D -nodefaultlibs -lc++ -lcxxrt -lthr -lm -lc -lgcc_s This gives a hint at the options I'd expect to be in use (other than -v and -std=3D...). When I looked around it did not appear to me that the FreeBSD ports infrastructure was set up to deal with g++*'s using libc++ --only with clang++ dealing with either libc++ or libstdc++ . --=20 You are receiving this mail because: You are the assignee for the bug.=
