Gem installation failling with "The compiler failed to generate an executable file" on cygwin
6,037
The solution for this error was (and is for all such errors) to have a look at the mkmf.log
file (for me, /cygdrive/d/d/Documents/.gem/ruby/extensions/x86_64-cygwin/ffi-1.9.8/mkmf.log
) and see which libraries are missing.
In my case, -lcrypt
and -lgmp
were failing, so I had to "cygwin-setup" libcrypt-devel
and libgmp-devel
.

Trying to install multiple gems on
cygwin
, I keep getting this error:/usr/share/ruby/2.2.0/mkmf.rb:456:in try_do': The compiler failed to generate an executable file. (RuntimeError)
This error is part of the full error message below:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /usr/bin/ruby.exe -r ./siteconf20150603-27012-w371hi.rb extconf.rb *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

Results logged to /cygdrive/d/d/.gem/ruby/extensions/x86_64-cygwin/ffi-1.9.8/gem_make.out
I tried all things I could find on google, out of which some do actually work including:
- Installing the cygwin package corresponding to the gem through cygwin setup
- Installing more cygwin packages, depending on the failing gem
But for this very specific example, I could not find what was missing...

-lv8
or-ltokyocabinet
so I had to give up.
