Issue #19677 has been updated by tagomoris (Satoshi TAGOMORI).


After the first successful build, I couldn't reproduce the build failure noted above.
In addition to it, the build just after a clean `git clone` finished without errors. So, the build failure may have been triggered by my dirty source directory.

Bug #19677: Failed to build ruby from the source code when following the guide

I followed the document "Building Ruby" (doc/contributing/building_ruby.md) and got build errors.
At the step of "5. Build Ruby: make install", the errors below happened:

```

I got a successful build when I tried `make ruby; make install` instead.
So, I'm assuming that the build script has a bug, or the document should be updated.
