goreleaser-cross

Docker container to turn CGO cross-compilation pain into a pleasure. It tested on variety of platforms. Custom sysroots also can be used.

Tip! Should you wish to see working examples instead of reading

Credits

This project is rather cookbook combing various projects into one. Special to osxcross for amazing cross-compile environment for OSX.

Docker

Docker images are available on both Github and Docker hub.

Images from version v1.17.4 are multi-arch. Supported host are listed in the table below

Host	Supported
amd64	✅
arm64 (aka aarch64)	✅

To run build with CGO each entry requires some environment variables

Env variable	value	required	Notes
CGO_ENABLED	1	Yes	instead of specifying it in each build it can be set globally during docker run -e CGO_ENABLED=1
CC	see targets	Optional
CXX	see targets	Optional
PKG_CONFIG_SYSROOT_DIR		Required if sysroot is present
PKG_CONFIG_PATH		Optional	List of directories containing pkg-config files

• PKG_CONFIG_SYSROOT_DIR modifies -I and -L to use the directories located in target's sysroot.
• The value of PKG_CONFIG_SYSROOT_DIR is prefixed to -I and -L. For instance -I/usr/include/libfoo becomes -I/var/target/usr/include/libfoo with a PKG_CONFIG_SYSROOT_DIR set to /var/target (same rule apply to -L)
• PKG_CONFIG_PATH - A colon-separated list of directories to search for .pc files.

Docker

Environment variables

• GPG_KEY - defaults to /secrets/key.gpg. ignored if file not found
• DOCKER_USERNAME
• DOCKER_PASSWORD
• DOCKER_HOST - defaults to hub.docker.io. ignored if DOCKER_USERNAME and DOCKER_PASSWORD are empty or DOCKER_CREDS_FILE is present
• DOCKER_CREDS_FILE - path to file with docker login credentials in colon separated format user:password:<registry>. useful when push to multiple docker registries required

  user1:password1:hub.docker.io
  user2:password2:registry.gitlab.com
  

• DOCKER_FAIL_ON_LOGIN_ERROR - fail on docker login error
• GITHUB_TOKEN - github auth token to deploy release

Sysroot howto

Most reasonable way to make a sysroot seem to be rsync and the example is using it. You may want to use the script to create sysroot for your desired setup. Lets consider creating sysroot for Raspberry Pi 4 running Debian Buster.

• install all required dev packages. for this example we will install libftdi1-dev, libusb-1.0-0-dev and opencv4

  ./sysroot-rsync.sh pi@<ipaddress> <local destination>

sshfs

Though sshfs is a good way to test sysroot before running rsync it introduces cons. Some packages are creating absolute links and thus pointing to wrong files when mounted ( or appear as broken). For example RPI4 running Debian Buster the library /usr/lib/x86_x64-gnu-linux/libpthread.so is symlink to /lib/x86_x64-gnu-linux/libpthread.so instead of ../../../lib/x86_x64-gnu-linux/libpthread.so.
