Issue #14964 has been updated by k0kubun (Takashi Kokubun).

Status changed from Open to Feedback

I succeeded to install msys1. I'm trying to reproduce your build error (and it's slowly proceeding), but your configure seems to have many options. Could you minimize the number of configure options that still reproduce your build failure?

I'm having trouble building Ruby 2.6 on Windows.

this is the first error:

I tried various CFLAGS, it looks like -mcrc32 helped

I tried to add -march=barcelona -mtune=barcelona -msse4a as the gcc documentation says, but it didn't help. It looks like these instruction are SSE4a specific and some headers are missing.

rev. https://github.com/ruby/ruby/commit/88975c821c99b852959958e2934de68a45be15e6
Windows 10 64bit, x86_64-w64-mingw32
GCC 7.2.0 - http://downloads.sourceforge.net/project/mingw-w64/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/7.2.0/threads-win32/seh
AMD FX-8300 8C

I can compile the lastest Ruby 2.5.1 with the same options.

Is it a known problem? Maybe GCC isn't supported on Windows yet?
