Hello, i have the following error in xcode while trying to build for ios :

Undefined symbols for architecture arm64:
"_glTexSubImage2D", referenced from:
DBX::ImageProcessor::update_RGBA_texture_GL(void*, bool) in libpdimf-arjni-ios-unity.a(ImageProcessor.o)
DBX::ImageProcessor::update_YUV_texture_GL(void*, void*, bool) in libpdimf-arjni-ios-unity.a(ImageProcessor.o)
"_glBindTexture", referenced from:

ld: symbol(s) not found for architecture arm64

I am using the following post process build project updater:

[PostProcessBuild]
public static void OnPostProcessBuild(BuildTarget buildtarget, string path)
{
if (buildtarget == BuildTarget.iOS)
{
string projpath = path + "/Unity-iPhone.xcodeproj/project.pbxproj";

PBXProject proj = new PBXProject();
proj.ReadFromString(File.ReadAllText(projpath));

string target = proj.GetUnityFrameworkTargetGuid();

// set a custom link flag
proj.AddBuildProperty(target, "OTHER_LDFLAGS", "-lz -lsqlite3");
// disable bitcode
proj.SetBuildProperty(target, "ENABLE_BITCODE", "NO");

File.WriteAllText(projpath, proj.WriteToString());
}
}

I checked the "Other links flag" under project settings and it contains the lz and lsqlite3 flags.
Software used : Unity 2021.3.2 , Xcode 13.4.1 and the latest version of your plugin


Regards the license files, i have put them both (android and ios) in the streaming assets folder with different names. Is that ok?

Thanks in advance for any help!

Yes, it's disabled

The toggle for the Auto Graphics it's no longer available under iOS in the recent versions of Unity, should i downgrade to an older version and build without Metal library?

Opening the project with unity 2020 and switching to OpenGLES 3 instead of Metal solved it.
Thank you!
