Thirdparty libraries

How to disable specific libraries

Now you can configure which library do you want to include for each platform. This process requires to configure and recompile the plugin for each platform that you want to support.

To automate the process we can include the plugin inside our UE4 project folder, and compile the plugin with our project.

So the first step is to download the plugin from the Marketplace.

Now we can copy

- Resources

- Source

- Thirdparty

- ParallelcubeAudioAnalyzer.uplugin

to our Project folder

We need to create a /Plugin/Marketplace/AudioAnalyzer/ folder in our project and paste the previous content of the plugin

We have edit two files to configure the plugin.

The first one disable the code related to the decoder and it is located on:

Warning

Source/AudioAnalyzer/Private/AudioAnalyzerConfig.h

Search the platform to configure and disable or enable the decoder changing the value of the macro by 0 or 1

How to disable OVR library code for Windows Platform

The second one is to avoid to include the library binary in the packaged project and it is located on:

Warning

Source/AudioAnalyzer/ParallelcubeAudioAnalyzer.Build.cs

We can’t set a Macro value in C# so to disable the library we need to comment the macro definition using a doble slash

How to disable OVR library binary for Windows Platform

Now we can open our project.

A dialog is showing up to request the build of the plugin for the editor.

If all goes well, this process will generate the binaries used by the editor when the project is opened

We can see a new folder in the plugin path that contain this binaries

and finally our project is ready to the development with a custom version of the AudioAnalyzer plugin

Note

If you want to change the plugin configuration again you need to delete the Binaries folder of the Plugin ot force the compilation
