Apologies. Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) Target: x86_64-apple-darwin13.1.0 Thread model: posix On Mac OS X 10.7, gcc -v *does accept* -static-libgcc, though, although it's also LLVM-based. No idea why they changed this in 10.9. Up till LLVM 3.3 there was a gcc plugin called DragonEgg which used gcc as a front-end and LLVM as the back-end. Now gcc is basically an alias for the clang front-end. Your proposed patch has two problems, unfortunately: * Don't check for $GCC. I don't care who the compiler thinks he is as long as it accepts -static-libgcc. * The gcc version check is wrong: -static-libgcc goes back way long (even 2.95 and perhaps even before). It did apply to -static-libstdc++, though I don't know what a version check buys us if the compiler accepts the option. Thanks for the explanation, that make sense. Please try the attached patch instead. Manual testing with Oracle Studio cc (which doesn't accept -static-libgcc) and gcc gave the correct results. I can confirm that this works with all three mingw targets (after installing autoconf 2.64) - thank you very much! Cheers, Tony

[Bug lto/60981] New: lto-plugin configuration doesn't test for -static-libgcc (OSX gcc - clang)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60981 Bug ID: 60981 Summary: lto-plugin configuration doesn't test for -static-libgcc (OSX gcc - clang) Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: lto Assignee: unassigned at gcc dot gnu.org Reporter: tony.theodore at gmail dot com Created attachment 32690 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=32690action=edit lto-plugin -static-libgcc configure.ac test Hi, When building on OSX, gcc is a symlink to clang and doesn't accept the -static-libgcc option. The attached patch basically copies the have_static_libs test from the top level configure.ac:1253 to the lto-plugin/configure.ac (removing the c++ parts) - it hasn't been tested as I don't have the right version of autoconf, but copying and modifying the corresponding section from configure works.
