Hi! I would like to build a plain C console app in Xcode. I have 5 source files added to a project and a library, say libMyLib.a. The C source files obviously use the library. I can't get this to work, the linker produces errors of type "Undefined symbols for architecture x86_64..." I have checked with lipo that the static library supports this architecture. I tried various options suggested on forums: setting paths to headers (absolute, as well as using $(SOURCE_ROOT)), setting Build Phases -> Link Binary With Libraries, using workspaces. The same source code compiles fine when using command line gcc. I have also tried setting additional linker flags in Xcode to those that I use with make. Nothing works. What am I missing? Thanks in advance!
