What did you do?

1. Copied contents of Down/Source into my project (I can't reference external frameworks)
2. Tried to build project

What did you expect to happen?

I expected the project to build successfully

What happened instead?

1. Build failed with error: unknown type name 'cmark_reference_map' in inlines.h
   • Fixed it by adding #include <references.h> in inlines.h
2. Build failed with multiple errors: No such module 'libcmark'
   • Tried removing import (thought module is not needed when sources are in same project) - that was a wrong way

That all happens Xcode 11.4.1, Legacy Build System.
Gonna give a try on New Build System

Maybe there is a guide on using Down as copied sources?

P.S: building with Down as CocoaPods dependency works fine

Looks like libcmark module is used to import c code in swift, so removing import was a wrong way.

Then the problem is No such module 'libcmark' - issue updated

Found that path to libcmark module.modulemap should be added to Swift Compiler - Import Paths.
Now receiving a lot of Could not build module 'Foundation' errors.
I suggest an importing loop created by cmark

Finally I've built it.
Can't say exactly what caused the problem, feels like some Xcode cache or bug resolved itself on 50th try of the settings that should work
Mostly I did what all guides say:

• Add C sources
• Create modulemap (cmark/include/module.modulemap)

In Podspec:

• spec.source_files - add sources
• spec.preservepath - add modulemap and .inc files
• spec.pod_target_xcconfig - add 'SWIFT_INCLUDE_PATHS' => '$(PODS_TARGET_SRCROOT)/<path to cmark modulemap>'
• Also had to configure spec.public_header_files, as pod generated umbrella caused build errors like unknown type name 'cmark_reference_map' in Unable to build Swift package in Xcode 11.4.1 #209

I'm a bit confused @Luten ; are you integrating it via pods or manually?
