Going in a different direction, what of the unchanged Makefile.inc1 code block: .if ${WANT_COMPILER_TYPE} == gcc || \ (defined(X_COMPILER_TYPE) && ${X_COMPILER_TYPE} == gcc) # GCC requires -isystem and -L when using a cross-compiler. --sysroot # won't set header path and -L is used to ensure the base library path # is added before the port PREFIX library path. CD2CFLAGS+= -isystem ${XDDESTDIR}/usr/include -L${XDDESTDIR}/usr/lib # GCC requires -B to find /usr/lib/crti.o when using a cross-compiler # combined with --sysroot. CD2CFLAGS+= -B${XDDESTDIR}/usr/lib # Force using libc++ for external GCC. .if defined(X_COMPILER_TYPE) && \ ${X_COMPILER_TYPE} == gcc && ${X_COMPILER_VERSION} >= 40800 CD2CXXFLAGS+= -isystem ${XDDESTDIR}/usr/include/c++/v1 -std=c++11 \ -nostdinc++ .endif .endif Why is that pair of -isystem uses that gives the old search order okay? Or was the block just missed? (Similarly for other options listed above.) Note: Locally I've reverted the -r335782 changes in order for my use of devel/*-gcc as cross compilers to work where they used to (hopefully: still building), restoring the historical search order for the directories for now. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)Received on Tue Jul 17 2018 - 04:27:29 UTC
