In /etc/make.conf, when I use, XCC= /usr/local/bin/clang40 XCXX= /usr/local/bin/clang++40 XCPP= /usr/local/bin/clang-cpp40 for ports that require c++ without clang in the base system, I get the error code make: "/usr/ports/Mk/Uses/compiler.mk" line 112:warning: "c++ -### /dev/null 2>&1" returned non-zero status
Base and the kernel builds well with this setting. Compiles that don't need c++ also work with this setting. I've compensated by adding CC= /usr/local/bin/clang40 CXX= /usr/local/bin/clang++40 CPP= /usr/local/bin/clang-cpp40 to the above. While this works for many ports requiring c++, it doesn't work for Rust, and programs that depend on it (Firefox, Thunderbird). It seems that XCXX is supposed to replace CXX fully, considering that XCC replaces CC, and XCPP replaces CPP when compiling other ports. The error message for compiling rust with all of the above (XCC, XCXX, XCPP, CC, CXX, CPP) set is couldn't find required command: "c++" This error happens whether the port option for lang/rust is set to compile with llvm40 or the bundled version. This is affected by /usr/ports/Mk/Uses/compiler.mk and I think this problem affects ports compiled with c++ in the base system as well.
