Also the Library I am trying to use (GiNaC) relies on another one (CLN). I will take care about that later and try to do CLN first. So now I created my new Project -> Cocoa Touch Static Library and added all the source into it. After I called the ./configure script in the CLN folder. When I try to compile I get these errors :
What is wrong ?
