So long as you have your per-configuration build products path set to $(BUILD_DIR)/$(CONFIGURATION) and your libraries and executables are using the same build directory then everything should just work as expected, i.e. debug libs will get linked with debug executable, release libs will get linked with release executable. Works for me, anyway. I think what can throw things out is if you're using a project which was automatically upgraded from e.g. Xcode 1.5, in which case the build paths can get set incorrectly for this kind of thing.

hi,
I am trying to use Xcode 2.2 to link several static libraries into an application. No they can't be dynamic libraries or frameworks, so lets not go there.
Initially I created the bunch of needed Xcode projects, one target each, and with the standard "release" and "debug" build configurations and built everything with the debug build configuration. There are no linkages between projects in the project files themselves.
The application project that uses the static libraries includes the static libraries from the debug folder, because that is what I had - debug builds of libraries.
Now I want to build a release version. So I went and built the release build configuration of everything.
The application won't link because it can't find any static libraries. That seems obvious since when the static libraries are included in the project you have to specify them down to the file. But I don't see a way to specify a static library based on the build configuration.
What is the magic part of the application project build configuration that controls where it looks for a static library based on the build configuration?
(Right now my work around is to put the static libraries in one place, independent of build configuration and link to that. So I can't keep a "debug" static library around for the "debug" version of the application and a "release" static library for the "release" version of the application.)

Take a look at your "Library Search Paths" settings. You probably need to tweak them to point to the Release library locations in the Release build configuration. From what you describe, you will have different paths in the Debug and Release build configurations.

I'm dealing with a similar problem and have understood that the only way to go is to add the needed static libraries in the "Other Linker Flags".
