[bug] - Cant run/build basic window

[cltWilly]

What happend?

I want simply run the exmaple code for hello world window, but i am keep getting error when trying to build or run the main.go

Any another project without giu works fine.
I was trying different mingw versions, but nothing seems to work. So i tried TDM-GCC but is the same. There is gcc -v

Using built-in specs.

Code example

main.go

package main

import (
	"fmt"

	g "github.com/AllenDang/giu"
)

func onClickMe() {
	fmt.Println("Hello world!")
}

func onImSoCute() {
	fmt.Println("Im sooooooo cute!!")
}

func loop() {
	g.SingleWindow().Layout(
		g.Label("Hello world from giu"),
		g.Row(
			g.Button("Click Me").OnClick(onClickMe),
			g.Button("I'm so cute").OnClick(onImSoCute),
		),
	)
}

func main() {
	wnd := g.NewMasterWindow("Hello world", 400, 200, g.MasterWindowFlagsNotResizable)
	wnd.Run(loop)
}

To Reproduce

1. copy the window example as in docs
2. run go run main.go or go build main

@cltWilly this might be related with gcc version. Could you try to compile using mingw (as the shared library was compiled using it).

[gucio321]

yes, this deffinitly might be the problem. You'r using gcc v10 and cimgui.a was compiled (according to its content) with GCC: (Rev1, Built by MSYS2 project) 14.2.0

Edit: we need to stop recommending tdm-gcc in our readme as it seems to be discontinued (last update in 2020)

ok i changed it to mingw64. and after like 5 minutes it finally build it :D. And I have a good workstation. So it works now thank you.

yeah, build time is unfortunately a bit painful...
This is mainly due to CGO not being parallelized enough. There was some progress on that issue recently iirc so maybe 1.24 will be a bit better.

Let me close this.
