Forgot to load Dependencies for Windows version of library in the GDNativeLib file

[JOELwindows7]

Which causes if the project exported, only Windows version will suffer from error no such method

Checked file:

• https://github.com/MightyPrinny/godot-FLMusicLib/blob/AssetLib/FLMusicLib/FLMusicLib.gdnlib (Asset Lib to be imported to own project)
• https://github.com/MightyPrinny/godot-FLMusicLib/blob/demo/FLMusicLib/FLMusicLib.gdnlib (demo project)

both files above forgot to load Dependency .dll files for Windows version of the Native Library. It seems for Windows version, the .dll library is separated hence the main FLMusicLib.dll requires dependencies which included next to it. for other platform, such as Linux, and Android, already had all in one .so file, so I suspect that it no longer require to have dependency.

bellow is the debug console output of exported application which is FLMusicLib demo.

to even clarify, I also implemented the FLMusicLib into my own project, made the implementation to use that when the music file is the format for the GMEPlayer, and it resulted the same. Invalid call. Nonexistent function 'play_music' in base 'Nil'

fixing problem

• Reopen the demo project
• open up the FLMusicLib.gdnlib and pay attention to GDNative Library bottom window.
• pay attention to Windows libraries fields.
• Load up all .dll files on the Dependency field.
• Export again
• now it works. both editing & executable

Solution

• commit an update to all related branch that finally loads all dependency for Windows version. The final result for file FLMusicLib.gdnlib should looks like

notice that in the section `[dependencies]`, I manually added other DLL files for Windows version, which you already aware that following fields above are empty. this way, made the WIndows version export finally works.

I should create pull request simply to fix this missing

[JOELwindows7]

Yeah! pull request!!

https://github.com/MightyPrinny/godot-FLMusicLib/pull/7

https://github.com/MightyPrinny/godot-FLMusicLib/pull/6

Be sure to test this first!

Keys for the test:

• Export to Windows
• Comparison between when editing project & exported binary
• other platforms
