Undefined Symbol Error #52

Closed rahulbelekar closed 1 year ago

rahulbelekar commented 3 years ago

I am getting the following error when I include the libssl.a and libcrypto.a and build the project

Xcode 12.4 iOS 14.4

I am only using libssl and libcrypto in my project. Also I have the header path to the "include" folder. Any idea why the compiler is throwing the below error?

This would happen if the library files you are using do not match the target architecture you are building.

What is the target architecture for your project (MacOS, iOS, iOS Simulator)? Also which library are you using (the build script builds libraries for multiple targets)?

I would also suggest trying to use the XCFrameworks libraries to help xcode find the right library for your target platform.
