Undefined symbols for x86_64 architecture #1

Closed cyprusad closed 7 years ago

Hello! I tried downloading and linking this library to a Swift 3 app today; I was attempting to test on simulator and kept running into

while trying to compile my project with the framework added

I tried the usual suspects of adding i386 and x86_64 to the Valid architectures for both ClippingBezier as well as PerformanceBezier frameworks respectively, and using the those products in my project, but no luck.

I don't know if this is an issue with the framework per so, or if I am just missing something altogether. Would appreciate your insight/experience on these type of issues @adamwulf ✌️

In your Build Settings, make sure to add -ObjC -lstdc++ to the Other Linker Flags. That should do the trick :)

Turns out, I also needed to include the PerformanceBezier.framework in addition to the ClippingBezier.framework in my project with the proper linker flags set, and then it worked. Thanks for weighing in!
