"Symbol can not be found" in the C makefile project codes in xcode

Question

I am creating a project makefile in xcode4.5 (OSX → Other → External Build System) and add to it a few files c . And I can make to successfully execute the project.

But he said to me "symbol not found" , When I try to go to the function definition.

I'm trying to find a way from google, for example, remove xcworkspace xcuserdata and folders and delete derivatives project data, etc. But they all fail. Any solutions?

By the way, my project is very simple and is here .

Answer 1

• Makefile and the code works fine from the command line.
• Set up a quick project in xcode (5.1.1 btw, this is what I have installed)
• OSX-> Drugoe-> Foreign build system
• Set the project directory in git checkout to create the project wizard.
• In setting External Build Tool Configuration-> Info install directory for the value git directory.
• Product-> Build
• It builds perfectly, it works fine.

Nothing more can be done to help, if the steps that I have taken, that something is wrong, you have to look at your project xcode dmg.
