Unable to compile in 4.16.2 #1

Thanks for posting this and writing the tutorials. I'm trying to do something similar with other third party libraries and this has helped a lot. I did run into an issue though. It looks like they've changed the module constructors to accept the argument ReadOnlyTargetRules instead of TargetInfo. I was unable to compile until I made the change in MyProject.Build.cs from this :

public bool LoadMyModule(TargetInfo Target)

to this: public bool LoadMyModule(ReadOnlyTargetRules Target)

Still not sure if everything is working correctly but it compiles now.

I think I was unable to compile for another reason, but this change did resolve a compiler warning.

Unable to compile in 4.20，the file opencv. build.cs have too much error

linjiangwei commented 5 years ago

it's a plugin for UE4 below version 4.16. when you use the higher version, you should do some modification to pluginname.build.cs https://answers.unrealengine.com/questions/764146/view.html hope this can help you.
