Go 生成fyne应用程序时glfw pkg配置错误

戈朗代码：

package main

import (
    "fyne.io/fyne/app"
    "fyne.io/fyne/widget"
)

func main() {
    application := app.New()
    window = application.NewWindow("Hello rohan")

    window.SetContent(widget.NewLabel("Hello again"))
    window.ShowAndRun()
}

当执行此代码时，我得到以下错误

# pkg-config --cflags  -- gl gl
Package gl was not found in the pkg-config search path.
Perhaps you should add the directory containing `gl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gl' found

希望有人能在这方面帮助我，或者就如何解决这个问题给我一些建议。

一些Linux系统缺少安装的图形库的编译头。谢天谢地，这只是开发所需——应用程序运行时不会遇到这种情况

对于Ubuntu或Debian，请尝试

sudo-apt-get-install-golang-gcc-libgl1-mesa-dev-xorg-dev

。

安装因平台而异，详细信息参见

中的详细信息可能是相同的问题，德国劳埃德船级社在此处和问题中引用了相同的服务

apt get install libgl1 mesa dev

使用WSL，您还需要运行X服务器才能显示GUI应用程序。确实要在Windows上构建Windows GUI应用程序，不应使用Linux子系统，因为这不会构建真正的本机应用程序。为什么不使用windows工具和MSYS2，如上所示可能是相同的问题，gl在此处和问题中引用了相同的服务
