Hi - I am on OSX Sierra and when I attempt to gem install gpgme, I get the following errors:

Building native extensions.  This could take a while...

Any news about this? I am having the same issue trying to install this

I have no idea, but this looks obviously wrong, unless you build it with --use-system-libraries:

checking for gpgme_op_export_keys()... no

Could you collect the complete logs with --disable-clean?

$ gem install gpgme -- --disable-clean
$ find <gem directory> -name config.log

I'm getting a different but similar error (also on high sierra)

************************************************************************

IMPORTANT!  gpgme gem uses locally built versions of required C libraries,
namely libgpg-error, libassuan, and gpgme.

If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall gpgme gem as
follows:

    gem install gpgme -- --use-system-libraries

And when I try that:

gem install gpgme -- --use-system-libraries
Fetching: gpgme-2.0.16.gem (100%)

Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

Provided configuration options:

extconf failed, exit code 1

Gem files will remain installed in /Users/me/.gem/ruby/2.1.5/gems/gpgme-2.0.16 for inspection.
Results logged to /Users/me/.gem/ruby/2.1.5/extensions/x86_64-darwin-17/2.1.0-static/gpgme-2.0.16/gem_make.out

Edit: looks like this is the error:

conftest.c:13:15: warning: implicit declaration of function 'gpgme_op_export_keys' is invalid in C99 [-Wimplicit-function-declaration]
int t(void) { gpgme_op_export_keys(); return 0; }

brew install gpgme fixes it
