@Christoph-Hart said in Move scripted algorithm to a third party C++ lib:
@ustk welcome to C++. Your .cpp file is probably not added to the Xcode project as translation unit (which is C++ gibberish for something that will be compiled).
I have seen that xcode might miss the file on StackOverflow but wasn't sure if it was my case and even less the how to :)
Why do you need to split it into .cpp and .h? If you want to keep the implementation organised like this, you need to use a header file which includes the two files.
For 2 reasons actually, my own experience, and be able to link existing libraries without too much modifications
