error: "Can't open dynamic library: cef_artifacts/libgdcef.dll" when execute a build for windows platform

[AaronClaros]

OS: windows 11
Godot version: 4.2.1

Description: gdcef extension works fine on godot editor, but when I try to export for windows, an execute the build, I get this error stack

ERROR: Can't open dynamic library: cef_artifacts/libgdcef.dll. Error: Error 126: The specified module could not be found..
   at: (platform/windows/os_windows.cpp:394)

this is how looks in editor, vs windows build

this is how looks the windows build folder: (I added "cef_artifacts" folder manually)

• it seems the .gdextension file is missing in your export. It's present in demos/xx/libs: try to copy the folder.

• from the screenshot, I see the demo2d is an old one. Try to update your repo to track HEAD of https://github.com/Lecrapouille/gdcef/tree/godot-4.x branch. Since huge changes have been made transitioning Godot 3 to Godot 4 with some regression risk for compiling with windows (Unable to build the extension for Godot 4 on Windows 11 machine #39): clean the folder gdcef/addons/gdcef/thirdparty/ before redoing a build.

Hello, I have the same problem. Browser runs fine in Godot Editor. But it doesn't work when I export it to Windows.

Build files:

$ ls -lr .
total 68024
-rwxr-xr-x 1 Pastew 197121   593920 Jun 10 00:37  libgdcef.dll*
-rw-r--r-- 1 Pastew 197121    68352 Jun 10 00:37 'CEF in 3D.pck'
-rwxr-xr-x 1 Pastew 197121 68880384 Jun 10 00:37 'CEF in 3D.exe'*
-rwxr-xr-x 1 Pastew 197121   109056 Jun 10 00:37 'CEF in 3D.console.exe'*

If I copy cef_artifacts to build folder it doesn't help.

Output from debug console:

I don't see libs directory you mentioned in this issue inside 3D or 2D demos in this version 0.10.0

[Lecrapouille]

Libs no longer exist with 0.10.0. Remove it. I will ask testing for export since I do not have windows

[Lecrapouille]

@Pastew effectively, Godot does not copy the cef_artfacts folder. From memory, Godot3 did it correctly. Maybe opening a bug on Godot team. You can copy it manually. Other point, there is a small issue on my side. In godot script "exported_artifacts" that can be set with CEF.initialize( is by default equal to the folder path holding with your binary instead of path to cef_artifacts, therefore forcing either to set it each time or to remove the folder cef_artifcats. Ok I'll fix it but also manage absolute pathes. Thnak you!

[Lecrapouille]

Sorry, I had no time for testing my last commit fixing. @Pastew if you want to check. I'll see to create a new tag

[Pastew]

Sure, I will test it when a new tag appears (but not earlier than June 22nd).

For now - I just moved cef_artifacts content to .exe's directory and it works.

[c0if]

Same problem here, and also caught something weird and a weird solution to the problem.

This solution isn't ideal because it's really messy and wastes more disk space, but adding the cef_artifacts content on to the root of exported build directory and adding the cef_artifacts folder with the same content works. Yes you really need to duplicate for it to work.

However, while I was debugging the error using Process Monitor in order to see what paths it was using, I saw that it's able to find the libgdcef.dll file just fine inside my cef/ folder, but for everything such as the libcef.dll, it's unable to find it and goes through most of the Windows filesystem, even though the libcef.dll is also inside the cef/ folder.

ok @pimhakkert we have to investigate
