Usage example for goreleaser-cross
Demonstrates how to cross-compile Go project with CGO dependencies.
Project depends on C/C++ libraries libftdi1, libusb-1.0, opencv4.
- Executable will try to detect FTDI 2232 boards with VID: 0x0403 and PID: 0x6010 and open channel 0.
- Then it lists serial number of all detected boards.
- Afterwards it will try to open camera with OpenCV and take test picture into your terminal
Example of output
version: 0.0.4
detecting ftdi devices
detected 1 device(s) with vid: 0x0403 pid: 0x6010:
[0] serial: FT4AYSJC
detecting camera using opencv...

Cross-compiles for targets:
- Darwin/amd64
- Linux/armhf (Raspberry Pi 4 aka RPI4)
- Linux/amd64 (should not be any issue to add this example)
This example is based on real working solution where Macbook is dev machine and RPI4 is end target. Cross-compilation is set for both darwin and linux to ensure nothing is broken with new commits
Sysroots are located in separate repo and added as submodule to current repo
- Darwin sysroot is created by simply copying libraries from
homebrew - Linux sysroot is created from RPI4 using this script
