Hi @wenchaomartin, could you post the full output of the go get -v? Thanks!

[wenchaomartin]

$ go get -v github.com/veandco/go-sdl2/sdl

output

Hi @wenchaomartin, I could not replicate the problems. Could you print the output of go version, uname -a, and go env as well? I wonder if it's because of old compiler or some mismatch in configurations. Thanks again!

Hi @wenchaomartin, how did you install the native SDL2 libraries? Did you do any modifications at all? From what I see, it looks like the compiler could not find the macro SDL_VERSION_ATLEAST and that might be caused by some missteps during the installation of native SDL2 libraries.

Perhaps you could try a fresh install of the native SDL2 libraries and see if it solves the problem? If possible, perhaps you could even do a fresh install of MinGW before that just to be sure everything is clean.

Hi @wenchaomartin, it looks like you haven't installed SDL2_ttf and SDL2_image. You should be able to install them the same way as SDL2.

@veeableful thanks a lot , i test sample code from read.me, popup a windows which contains red rectangle .
