Building a Linux Image on Mac
Once can do cross-compilation or build the executable in a local Linux container. This section describes how to build the executable from a local Linux container.
First, identify or build a "builder" image that contains the Go build tools. Let's assume that such an image is example.com/go1.22-builder:latest.
If your project does not declare dependencies on local unpublished module code, it is sufficient to mount the project directory in the build container. However, if the project declares dependencies on local unpublished module code, then we need to mount the directory that contains both source trees. Assuming we're building the project /Users/ovidiu/src/github.com/orgA/projectA and projectA declares a local dependency on ../../orgB/projectB, when we need to mount their common parent /Users/ovidiu/src/github.com:
docker run --rm -it --mount type=bind,src=/Users/ovidiu/src/github.com,target=/src example.com/go1.22-builder:latest
cd /src/orgA/projectA
./build
The build process will place the executable somewhere inside the source directory, depending on how the build system is set up.
The executable will be accessible from Mac.
To verify it is indeed Linux executable format:
file ./myexec
ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, Go BuildID=..., with debug_info, not stripped
