Build Fails IL2CPP

Hi,

I get this error when building my app. Not sure how to troubleshoot, perhaps someone can help me.

Exception: C:\Program Files\Unity\Hub\Editor\2020.1.16f1\Editor\Data\il2cpp/build/deploy/netcoreapp3.0/il2cpp.exe did not run properly!

See [UWP] [IL2CPP] Deploy Issue

thanks Tautvydas-Zilys. That’s strange however, I searched my solution for this and only found one file using it in UMP pro plugin. However, those lines were allready wrapped in #ifdefs restricting this to iOS and WebGL:

#if UNITY_IOS || UNITY_WEBGL

Apart from there the [DllImport("__Internal")] is not mentioned anywhere i my project.

Tautvydas-Zilys · December 21, 2020, 6:06pm

What that in the “LinuxInterop” class?

bjornsyse · December 22, 2020, 4:50pm

Hmm, I found this now. It didn’t show up in my first searches because on how I formulated the search string. NativeInterop.cs has this code:

private const string LIB_LIN = "__Internal";

...

  private static class LinuxInterop
        {
            [DllImport(LIB_LIN, SetLastError = true)]
            internal static extern IntPtr dlopen(string fileName, int flags);

            [DllImport(LIB_LIN, SetLastError = true)]
            internal static extern IntPtr dlsym(IntPtr handle, string symbol);

            [DllImport(LIB_LIN)]
            internal static extern int dlclose(IntPtr handle);
        }
