cgo-cross-compile-in-linux-for-darwin

Usage

• First run the ./build-oclang.sh to make build environment
• After the building you can do anything you need like go

   GOOS=darwin GOARCH=amd64 ./go.sh build -o xxx ./path/to/your/project/main.go
   GOOS=darwin GOARCH=arm64 ./go.sh build -o xxx ./path/to/your/project/main.go

PS

This Shell will generate an Apple compilation environment for you. And after generating and configuring the compiled environment, the configuration will be exported to the environment variable in build-oclang.sh will export:

  echo "export PATH=$OSXCROSS_PATH/target/bin/:$PATH" >>/etc/profile
  echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH" >>/etc/profile

Then go.sh will use TOOLCHAIN path point to osxcross/target/bin:

readonly TOOLCHAIN="$(pwd)/../build/osxcross/target/bin"

You can also change the TOOLCHAIN path to absolute path,then copy the go.sh to the system path for used at global. Or you can use go with settings like in go.sh, The configuration in go.sh is very simple.
