I guess you are doing something with includes, or how you compile project.

Make sure the static library and your project are compiled with the same compiler version.

The webui.js is a virtual file inside webui library, you don't need to generate it or to do anything with it, just add <script src=\“webui.js\”></script> to your HTML.

[AlbertShown]

Try this:

#include "webui.hpp"
#include ... // Your project includes here

int main() {
	webui::window my_window;
	my_window.show_browser("<html><head><script src=\"webui.js\"></script></head> TEST </html>", Edge); // Or Chrome, Firefox...
	webui::wait();
	return 0;
}

Hi, @Hunlongyu, I can't reproduce the issue, whatever I do, it's always working fine for me.

• Did you try to build webui from source?
• Can you compress the full project folder and share it here? If not possible, then can you confirm that main.cpp is the only source file in your project?

1. Haven't tried it.
2. Confirmed that there is only one main.cpp.

[AlbertShown]

Can you please compress the full project folder and share it here?

@Hunlongyu @LoseYouNow Try using this

Where is main.cpp?

Because my test runs well, I want to test your own test project to try to reproduce the issue.

Thank you @Hunlongyu, yes, I can reproduce the issue.
I'm investigating it.
