Overview

Dockerfile for Nim cross-compiler

packages

• Nim: dom96/choosenim
• CrossCompiler
  • Windows: mingw-w64
  • MacOS: tpoechtrager/osxcross -> andrewd/osxcross
  • Linux: gcc-multilib is installed so compiling 32 bit works
  • Linux: musl

Usage

Example compilation

echo 'echo "Hello World"' > hello.nim
docker run --rm -v `pwd`:/usr/local/src \
   chrishellerappsian/docker-nim-cross:latest \
   nim c --os:windows --cpu:amd64 --out:hello64.exe hello.nim

docker run --rm -v `pwd`:/usr/local/src \
    chrishellerappsian/docker-nim-cross:latest \
    nim c --os:macosx --cpu:amd64 --out:hello32.osx.bin hello.nim

Look at example directory.

Adding libraries

See the example/libssh directory for an example of adding an updated library to the build process.

The example brings libssh2 up to date so that the Nim ba0f3/ssh2 module can be built and tested.

See the test scripts test_sftp and test_scp for verifying sftp and scp work properly from within your Nim code. Each shell script should work unmodified to access the public Rebex test server
