A Swift API for the

Wasmer Installation for Swift

This works on either Intel or M1 Macs.

Installing Wasmer itself is easy:

curl https://get.wasmer.io -sSfL | sh

Or install a tarball: Wasmer 1.0.0 wherever you like.

To work, the Swift Package Manager requires a pkg-config file in a system location. Fortunately wasmer config can generate one for you:

wasmer config --pkg-config > /usr/local/lib/pkgconfig/wasmer.pc

Unfortunately the generated file is a little b0rked in 1.0.0. Open up the file in your favorite editor:

emacs /usr/local/lib/pkgconfig/wasmer.pc
mate  /usr/local/lib/pkgconfig/wasmer.pc
open  /usr/local/lib/pkgconfig/wasmer.pc

And adjust two little things:

  1. remove the /wasmer from the Cflags line, it should then read:

Cflags: -I/Users/helge/.wasmer/include

  1. add -lffi to the Libs line, it should then read:

Libs: -L/Users/helge/.wasmer/lib -lwasmer -lffi

(the latter is only required when linking static libs, but doesn't hurt either way).

To link statically (recommended), move libwasmer.dylib out of the way:

mv ~/.wasmer/lib/libwasmer.dylib ~/.wasmer/lib/libwasmer.dylib-away

(Dynamic linking should also work, but you'd need to ensure that the dylib is in the dynamic library lookup path.)
