You’ll probably want to configure extra compiler flags if that’s possible. You could also bite the bullet and build your C libraries with SwiftPM as well. Hopefully someone on swift-build-dev can help you out.<div class=""><br class=""></div><div class="">CC-ing Ankit<div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Mar 28, 2017, at 5:09 PM, Kelvin Ma <<a href="mailto:kelvinsthirteen@gmail.com" class="">kelvinsthirteen@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">How do I compile a project with many modules?

At a low level, you can create a module.map file and use -L/-l flags in your invocation of Swift. If you want to do so at a higher level, then perhaps SwiftPM can.
