Hello QL community,

I am working using Xcode 8.3.1 where I have successfully built Quantlib as a dynamic lib. I have also started a small project on the side where I use QL and when trying to link against it, I get the following linking messages:

Note that I have set up the correct QL Preprocessor flag to use the specific constructors QL::Date(const boost::posix_time::time& ). I am using the standard library libc++ and gnu++0X as a compiler. I have successfully built the other project on Eclipse in the past, but for some reason I can’t get it to build using Xcode.

Your help is much appreciated.

Thanks
Amine

Re: Linkage errors against QL under Xcode 8.3.1

CK TUNG
either your library does not have the required x86_64 architecture or you did not link the it properly in xcode.

For xcode, it is better to use framework.

Re: Linkage errors against QL under Xcode 8.3.1

Luigi Ballabio
Just to check:
- how did you set the preprocessor flag? Did you do it when compiling both the library and your project?
- how are you adding QuantLib to your project?
