Hello,

I’m building fine for Windows, Linux, but when using LinuxArm64 unreal build tool returns me an error saying it cannot find the libfmod.so files.

I created a folder called LinuxArm64 inside fmod plugin and it seems to search in here for libraries. I saw a post of an fmod moderator saying to download the API and copy the LinuxArm64 libraries, didn’t worked as it says inside my cooked builds:

/LinuxArm64/RNRCTribute-LinuxArm64-Shipping: error while loading shared libraries: libfmod.so.13: cannot open shared object file: No such file or directory

What should I do to compile my project for LinuxArm64 with fmod (2.02.28) for UE5.3.2 ?

Hi,

Unfortunately, building to Arm64 is not currently support. However we are tacking interest in the feature and I will add your interest.

In the meantime, could you try renaming the `libfmod.so.13` to `libfmod.so` and make sure that you have the following in your `FMODStudio.Buid.cs` after line `131`

```auto
else if (Target.Platform == UnrealTargetPlatform.LinuxArm64)
{
    libPath = System.IO.Path.Combine(libPath, "arm64"); // <-- Make sure this matches the location of the .so files in your project
    linkExtension = ".so";
    dllExtension = ".so";
    libPrefix = "lib";
}

```

Hope this helps
