requiring 'process_shared' after installing gives this error:

I have these .bundle files installed in the gem directory when the gem builds:

ext/helper/helper.bundle
ext/pthread_sync_helper/pthread_sync_helper.bundle
lib/helper.bundle
lib/pthread_sync_helper.bundle

I symlinked lib/helper.bundle to lib/process_shared/posix/helper.bundle and that seems to have fixed it.

Well that was dumb of me! I think I have fixed extconf.rb to that file gets installed in the correct location.

Thanks for the report.

[notEthan]

cool, thanks. seems to work

Hi pmahoney!

This (or something really similar) is still an issue at least on Fedora 21 and 22. On Both I'm getting something like:

/home/choms/.gem/ruby/gems/ffi-1.9.8/lib/ffi/library.rb:133:in `block in ffi_lib': Could not open library '/home/choms/.gem/ruby/gems/process_shared-0.2.0/lib/process_shared/posix/helper.so': /home/choms/.gem/ruby/gems/process_shared-0.2.0/lib/process_shared/posix/helper.so: cannot open shared object file: No such file or directory (LoadError)

On F21 ruby2.1.6 helper.so is located at .gem/ruby/gems/process_shared-0.2.0/ext/helper/helper.so
On F22 ruby2.1.6 is located at .gem/ruby/extensions/x86_64-linux/process_shared-0.2.0/process_shared/posix/helper.so

Can you please take a look on this issue?

[pmahoney]

@Choms I believe I have patched this, at least for F22. Not sure exactly for F21. Are you able to test this out for me? I published a pre-release gem, version 0.2.1a. You can install it with gem install --prerelease process_shared-0.2.1a, or use the latest from git.

[pmahoney]

@Choms Make that gem install --prerelease process_shared-0.2.1b

[Choms]

@pmahoney that fixed it (testing on F21), thanks! :)

[pmahoney]

@Choms thanks for testing. I've released version 0.2.1 with the fix.
