How to build a swift executable for Linux on macOS

I am trying to build a swift executable on my MacBook for my Linux vServer.

I already tried using swiftc -target "x86_64-linux test.swift, but my macOS swift compiler shows this error: <unknown>:0: error: unable to load standard library for target 'x86_64--linux'

So I looked around and found this question: Swift on OS X compiling for Linux? and tried out this example script from apple to setup a cross-platform toolchain.

After trying to build a module like shown in the example text of the script, it compiled, but on my linux machine I now get this error: error while loading shared libraries: libswiftCore.so: cannot open shared object file: No such file or directory which is strange, because swift is properly installed on my Linux machine and works.

So have I done anything wrong while cross-compiling the project, or is there a problem on my Linux machine? Also I wonder, if there is a more simple way of compiling a project for Linux on macOS, like changing the Build Settings in Xcode or something?

Thanks in advance,
Jonas

This just means it couldn't locate the linked library. If your libswiftCore.so located at /usr/lib/swift/linux you can run LD_LIBRARY_PATH=/usr/lib/swift/linux ./<your executable for linux> and it will work like a charm.

You can also set LD_LIBRARY_PATH variable to just execute the binary.
