Is it possible to compile and include C libraries with the Swift package manager?

Question

I've tried to just include the header and c files but they seem to be ignored

Answer 1

it is possible but the usual way to do it is to define a seperate package called 'Csomething' where you simply prefix the C library name with a capital C and host it on Github. The C package only need consist of an empty Package.swift file and a module.modulemap. In the module.modulemap you refer to where the C headers are:

module CPackage [system] {
  header "/usr/local/include/myheader.h"
  link "libraryname"
  export *
}

Thus in your original package, you simply put a dependency in for the CPackage e.g.:

.Package(url: "https://github.com/aleph7/CHDF5.git", majorVersion: 1)

and then you can import CPackage

https://github.com/aleph7/CHDF5 is a good example of a simple C Package
