Use only in gemfile? about gem-compiler HOT 3 CLOSED

Hello @fxfactorial and thank you for your questions.

When you say:

So I have successfully created unf_ext-0.0.7.4-x86-mingw32.gem on windows, moved that to my project

Please note that the generated binary is bound to Windows platform. Attempt to be use or install on another platform will not work.

Perhaps you might want to use bundle package instead.

In theory you can place multiple platform gems within vendor/cache and let bundle install --local automatically detect them.

You might need to store both ruby (non-platform specific) and platform specific gems in the cache.

Which I guess is because the binary formats are different, but there must be a way to get around this because it shouldn't matter, we're just moving it around, not running it.

Actually, it does matter. A gem for a different platform might no be found on a different one. Also if you're using Bundler lockfiles, it might contain some locked dependencies that are platform-specific and those cannot be installed under a different OS.

On a separate note, I see unf_ext already provides binaries for different platforms, so I'm not sure the role of gem-compiler on your question.

Hope that helps. Closing this now.

If you have an specific question related to gem-compiler itself, please feel free to open a new issue.

Cheers.

@luislavena Thanks for the quick reply!

ya, I'm building on OS X and want to use on windows, but the hassle of bundle install --local is that it wants everything in the dir, whereas I just want a selected group of gems to be used locally, rest downloaded from rubygems. I tried in the Gemfile itself, via :path => ./where/unf_ext-0.0.7.4-x86-mingw32.gem/is/located/ but then I get a Could not find gem 'unf_ext' in source at ./some-path.

Hello @fxfactorial I just realized from your sample:

gem 'unf_ext', :path => './'

The :path option indicates Bundler to look for unf_ext source in the given directory, not a packaged gem file.

Please see my response in #26 and reach out to Bundler for further assistance with it's usage.

Cheers.
