Yup this is the problem with using the ports compiler as the "host" compiler: > # echo '' |/usr/local/bin/gcc49 -v -x c++ - -o /dev/null > Using built-in specs. > COLLECT_GCC=3D/usr/local/bin/gcc49 > COLLECT_LTO_WRAPPER=3D/usr/local/libexec/gcc49/gcc/x86_64-portbld-freeb= sd11.0/4.9.4/lto-wrapper > Target: x86_64-portbld-freebsd11.0 > Configured with: ./../gcc-4.9-20160210/configure --with-build-config=3D= bootstrap-debug --disable-nls --enable-gnu-indirect-function --libdir=3D/= usr/local/lib/gcc49 --libexecdir=3D/usr/local/libexec/gcc49 --program-suf= fix=3D49 --with-as=3D/usr/local/bin/as --with-gmp=3D/usr/local --with-gxx= -include-dir=3D/usr/local/lib/gcc49/include/c++/ --with-ld=3D/usr/local/b= in/ld --with-pkgversion=3D'FreeBSD Ports Collection' --with-system-zlib -= -with-ecj-jar=3D/usr/local/share/java/ecj-4.5.jar --enable-languages=3Dc,= c++,objc,fortran,java --prefix=3D/usr/local --localstatedir=3D/var --mand= ir=3D/usr/local/man --infodir=3D/usr/local/info/gcc49 --build=3Dx86_64-po= rtbld-freebsd11.0 > Thread model: posix > gcc version 4.9.4 20160210 (prerelease) (FreeBSD Ports Collection) > COLLECT_GCC_OPTIONS=3D'-v' '-o' '/dev/null' '-mtune=3Dgeneric' '-march=3D= x86-64' > /usr/local/libexec/gcc49/gcc/x86_64-portbld-freebsd11.0/4.9.4/cc1plus = -quiet -v - -quiet -dumpbase - -mtune=3Dgeneric -march=3Dx86-64 -auxbase = - -version -o /tmp//ccA75yFy.s > GNU C++ (FreeBSD Ports Collection) version 4.9.4 20160210 (prerelease) = (x86_64-portbld-freebsd11.0) > compiled by GNU C version 4.9.4 20160210 (prerelease), GMP vers= ion 5.1.3, MPFR version 3.1.3, MPC version 1.0.3 > GGC heuristics: --param ggc-min-expand=3D100 --param ggc-min-heapsize=3D= 131072 > ignoring nonexistent directory "/usr/local/lib/gcc49/gcc/x86_64-portbld= -freebsd11.0/4.9.4/../../../../../x86_64-portbld-freebsd11.0/include" > #include "..." search starts here: > #include <...> search starts here: > /usr/local/lib/gcc49/include/c++/ > /usr/local/lib/gcc49/include/c++//x86_64-portbld-freebsd11.0 > /usr/local/lib/gcc49/include/c++//backward > /usr/local/lib/gcc49/gcc/x86_64-portbld-freebsd11.0/4.9.4/include > /usr/local/include > /usr/local/lib/gcc49/gcc/x86_64-portbld-freebsd11.0/4.9.4/include-fixe= d > /usr/include > End of search list.

It does not have /usr/local/lib in the default library path as far as I can tell. It's also broken for its -rpath (noted in its pkg-message). So having a default /usr/local/include path seems odd. Adding -isystem /usr/include to fix this is probably possible but there's a risk someone will remove it as redundant. In this case I wish /usr/include was first but I'm not sure what impact that would have on consumers expecting /usr/local/include (and /usr/local/lib) overrides to work, though they would need to pass a -L /usr/local/lib anyhow and would likely be passing -I /usr/local/lib too. --=20 Regards, Bryan Drewery
