Undefined symbols for architecture arm64 #2

Closed moax closed 7 years ago

moax commented 7 years ago

Hi, I also downloaded and implemented your framework into my swift project. I included the PerformanceBezier and the ClippingBezier Frameworks via bridging header.

In the build settings, I added "-ObjC++ -lstdc++" (I also tried with "-ObjC -lstdc++") under OTHER_LDFLAGS. Before doing this, the app was compiled, but when I called the function, it gave a libc++abi.dylib: terminating with uncaught exception of type NSException Error.

With the updated linker flags, it gives:

hrm, not sure about this. you may try the -all_load flag as well and see if that fixes it.

I managed to resolve the issue now. I did not add the linker flag -lstdc++ in the framework xcodeproject on compiling. After adding it there, the frameworks load correctly and it works now. Thanks for your excellent work!
