As part of testing that an environment seemed stable, an environment based on head -r320570 and ports -r444872 with gcc being lang/gcc7-devel that is installed on amd64, I tried: script ~/ports_typescripts/phoronix-try-00-typescript portmaster -DK benchmarks/phoronix-test-suite in part because it has: USE_GCC= any and I'm using: DEFAULT_VERSIONS+=perl5=5.24 gcc=7 in /etc/make.conf and the gcc that I have installed is lang/gcc7-devel. This should also have been a test of the adjusted-header removal that has been applied to lang/gcc7-devel (but not a old environment's build used under a modern system environment). But the result was a surprise: the log file shows all the build as using cc and in my context cc is: # cc --version FreeBSD clang version 4.0.0 (tags/RELEASE_400/final 297347) (based on LLVM 4.0.0) Target: x86_64-unknown-freebsd12.0 Thread model: posix InstalledDir: /usr/bin Configure repeatedly shows: checking for gcc... cc . . . checking whether we are using the GNU C compiler... yes In fact "phoronix-test-suite diagnostics" reports: COMPILER = Clang 4.0.0 (SVN 297347) + LLVM 4.0.0 So clang is being treated as an example of gcc as far as I can tell. === Mark Millard markmi at dsl-only.net
