Thanks for clarifying. I will try out both of your tips.

% gcc --version gcc (GCC) 6.1.1 20160802 I'm building with the current gcc just fine. The line to build with an older version of gcc is already in the PKGBUILD. Just enable it. The bug is due to the C++ ABI change. On some systems link picks the right library. On others it is necessary to enable LD_PRELOAD to force the right one. I'm hoping someone has an explanation of why library selection is so erratic.

@petterk That's your problem. You're compiling with a compiler not tested enough and prone to bugs like this. Downgrade to arch's GCC 5.3 and you'll be able to build GCC 4.9.4 Also note that if you want GCC 4.9.4 for compiler reliability, I suggest you update to GCC 5.4 after downgrading to GCC 5.3. It's just as reliable as GCC 4.9.4 but newer.

To clarify: $ gcc --version gcc (GCC) 6.1.1 20160802

libstdc++.so.6: version `GLIBCXX_3.4.21' not found No compile errors on Arch Linux or Manjaro. Compile error on Antergos. To compile, enable the 2 LD_PRELOAD lines.

With LLVM & GCC5 installed build might fail due to this: /tmp/gcc49-multilib/src/gcc-build/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /usr/bin/../bin/../lib/bfd-plugins/LLVMgold.so) This was also the issue with gcc48, but this commit fixed it via environment-variables: https://aur.archlinux.org/cgit/aur.git/commit/?h=gcc48&id=d6c1e9ab18bccca006a5107a6db2b1d25c8a613a Also see the comments for more info: https://aur.archlinux.org/packages/gcc48/?comments=all Maybe this should be included here too?

I am just building this package. The tests are very time consuming and probably have no valuable effect. Can these not be disabled by default?

I tried to build with GCC 5.1.0 and GCC 4.9.2 (from Rollback machine), both failed. What version are you using to (successfully) build?
