Installation steps for Windows

1. Install the GO Language for Windows
2. Install MSYS 2
3. Open MSYS 2 bash and execute this command :

pacman -S mingw-w64-x86_64-gcc

4. Add the GCC binaries to your Windows PATH by executing these two lines in your cmd. (This should be the correct path if you left everything by default during the MSYS 2 install)

setx PATH "%PATH%;C:\msys64\mingw64\bin"

refreshenv

5. Download the Harfang Go package :

go get github.com/harfang3d/harfang-go/v3

6. Run any harfang program :

go run example_harfang_app.go

Test the Go tutorials

1. Download the tutorials https://github.com/harfang3d/tutorials-hg2

and unzip them to your computer (eg. d:/tutorials-hg2).

2. To compile the tutorial resources, download assetc for your platform: https://dev.harfang3d.com/releases/

3. Drag and drop the tutorial resources folder on the `assetc

executable -OR- execute assetc passing it the path to the tutorial resources folder (eg. assetc d:/tutorials-hg2/resources).

After the compilation process finishes, you should see a resources_compiled folder next to the resources folder. You can now

execute the tutorials from the folder you unzipped them to.

tutorials-hg2>go run draw_lines.go

Alternatively you can open the tutorial folder and run the provided debug targets using Visual Studio Code
