Hi all,I have an external c++ static library and want to use it in my cocoa project. I just drag the .a file into my project but seems my code didn't find the methods in the library. I guess maybe I need to set some link path or so, but I don't know how to set and which parameter, does anyone have experience about it?suppose I have a libTest.a static library and there is a method called int showMeTheResult(). I want to use this method in my objective-c class (which is part of my cocoa project), how to do it step by step?
You drag it into your project, however, there are two things you must know about static libraries:
1. The linker normally only imports the symbols it thinks it needs. Sometimes it gets it right, but often I've seen it get it wrong (and more often than not, it gets it wrong when dealing with non-C libraries). If it's not importing symbols for you, then you need to add the -all_load linker flag to the other linker flags build setting.
2. If your static library has the same name as a dynamic library in the libraries paths, then the linker will always link to the dynamic library over the static one. There's no way to get it to change this behavior. One workaround is to remove the static library from the link build phase, and add an absolute path pointing to the static library to the other linker flags build setting.
