cimgui-go 1.3.0 mingw build failure on win10

Im using mginw32, having these sdl libs installed:

mingw-w64-ucrt-x86_64-SDL2 2.30.10-1
mingw-w64-ucrt-x86_64-SDL2_gfx 1.0.4-2
mingw-w64-ucrt-x86_64-SDL2_image 2.8.2-3
mingw-w64-ucrt-x86_64-SDL2_mixer 2.8.0-2
mingw-w64-ucrt-x86_64-SDL2_ttf 2.22.0-1

got errors as below. it looks like cimgui-go was linking some static libs shipped with the package?

@shellohunter which code are youb uilding? As far as I see it is something about SDL. Does it origin from sdl backend or imgui itself?

also, lemma say: our github CI can't reproduce https://github.com/AllenDang/cimgui-go/actions/runs/12464437434/job/34788540130

@gucio321

I'm building a cimgui-go demo with the ebiten backend. As far as I can tell, the link script were linking to the static lib under cimgui-go/lib. Those missing symbols were not found from [email protected]\lib\windows\x64\libSDL2.a, but they do exists in the lib installed by mingw, as below:

for example, GameControllerGetSteamHandle was reported missing.

PS > dumpbin.exe .\libSDL2.a | grep GameControllerGetSteamHandle


PS > nm C:\msys64\ucrt64\lib\libSDL2.dll.a | grep GameControllerGetSteamHandle
0000000000000000 I __imp_SDL_GameControllerGetSteamHandle
0000000000000000 T SDL_GameControllerGetSteamHandle

while GameControllerGetAxis was found in both libs.

PS > dumpbin.exe .\libSDL2.a | grep GameControllerGetAxis
          10 .rdata$.refptr.SDL_GameControllerGetAxisFromString_REAL
          10 .rdata$.refptr.SDL_GameControllerGetAxis_REAL


PS > nm C:\msys64\ucrt64\lib\libSDL2.dll.a | grep GameControllerGetAxis
0000000000000000 I __imp_SDL_GameControllerGetAxisFromString
0000000000000000 T SDL_GameControllerGetAxisFromString
0000000000000000 I __imp_SDL_GameControllerGetAxis
0000000000000000 T SDL_GameControllerGetAxis

a few questions:

what's the version of static libs like [email protected]\lib\windows\x64\libSDL2.a? maybe out of sync?
I can see 2 cimgui-go were installed into my go dir. they have the same content. but the 2nd one has a ! mark inside the path. so, why they two? and why the exclamation mark here?

They are compiled from thirdparty/ clones of these libraries so they shhould match imgui version as well.

Generally this is a question to @golang

Could you try to:

clone this repo
clean go cache
run examples/glfw (or examples/ebiten)

First of all this should not try to build SDL backend so no symbols confusion should happen
