With the recent change to roc, this is not necessary anymore. Now, it is possible to preprocess a go-platform, as you would preprocess any other platform. The user of the platform does not have to install or run go. He/She can just use the prebuilt-platform, and let the surgical linker combine the go-platform and the roc code.
A go-platform now behaves the same as any other platform.
To preprocess a go-platform, you can use the following commands:
roc build --lib path/to/example/main.roc --output platform/libapp.so
CC="zig cc" go build -C platform -buildmode=pie -o dynhost
roc preprocess-host path/to/example/main.roc
roc run --prebuilt-platform my_app/main.roc
Awesome, thanks for sharing this!
