'libmarkdown' error `'mkdio.h' file not found` when using the Markdown library after installing Discount via brew #8

Open dotZak opened 7 years ago

Hello!

After running brew install discount I can see that discount did properly install. However, Swift can't compile my app without using the following command:

swift build -Xcc -I/usr/local/include -Xlinker -L/usr/local/lib -Xswiftc -target -Xswiftc x86_64-apple-macosx10.12

I'm really new to this type of development and unfamiliar with the environment, so I am hoping this is not a real issue and is just some dummy error on my part.

This seems to be related to #3, which should have been resolved via a release for libmarkdown. Is there a status update on that?

Do you mind providing some insight on the issue?

PS. I'm following the Server-Side Swift book by @twostraws and it's been excellent. I've reached a project in the book that uses your library and that's when I found this issue.

System info

macOS 10.12.5 Xcode8.3.3

Same issue. Thank you for the working command. I am on the same lesson in that book and ran into the exact same issue. Hopefully it will be resolved soon.

I have the identical issue, but I've temporary resolved it with the "working" command. Thanks a lot, @dotZak!
