Hey peeps!
So, I’m here with Mac C++ project.
I’ve been able to successfully build Linux and Win projects, but with Mac, it seems like I’d need to connect the FMOD library through an rpath, but I have 0 idea how to do that.
I got 4.22.3 UE4 version with MacOSx 10.14.5, FMOD integration 1.10.14.
Integration is installed nicely, all is working in PIE, build is successful.
Upon opening I get an error on startup:
> Termination Reason: DYLD, [0x1] Library missing
>
> Application Specific Information:
> dyld: launch, loading dependent libraries
>
> Dyld Error Message:
> Library not loaded: @rpath/libfmodL.dylib
> Referenced from: /bb/\*/Detective.app/Contents/MacOS/Detective
> Reason: image not found
I tried to use integration right from the downloads, and also tried rebuilding it, with same result.
From what I understand, I need to add the libraries of FMOD to rpaths?
If so, how and why would i do that?
