Static Library path nightmare from hell

Question

This is the point. I have a subproject (static library) created. The library compiles well. No errors. When I include this library inside a project and imports a header from that library on the project the library fails to compile because it cannot find a path that belongs to itself.

After following a bunch of tutorials on the web on how to create a static library and embed that in a project, I don't know which one is the correct one, because I have tried all and all failed and some differ.

This is how the library is set:

---

STATIC LIBRARY

BUILD SETTINGS:

1. Public header folder path = $(BUILT_PRODUCTS_DIR)
2. Header search path = $(SRCROOT) (recursive)

BUILD PHASES

COPY FILES = 1 file, myLibrary.h that is basically empty (created by xcode when I used the static library template to start the library.

no ADD COPY HEADERS phase

---

MAIN PROJECT

BUILD SETTINGS

1. Header search path = empty
2. User header search path = $(BUILT_PRODUCTS_DIR) (recursive)
3. Always search user paths = YES

BUILD PHASES

1. Yes, myLibrary.a is on target dependencies

   ---

What amazes me is that the library compiles fine alone but when put inside a project, is unable to find a header that belongs to the own library.

NOTE: I have also tried to create a copy headers phase on the library making public all .h on that library, but it failed too.

This is an example of one error:

/Users/mike/Library/Developer/Xcode/DerivedData/MyApp-dnaimaovscreasadhmvgttwjnabc/Build/Products/Debug-iphoneos/include/myLibrary/ccTypes.h:39:9:
fatal error: 'Platforms/CCGL.h' file not found
#import "Platforms/CCGL.h"

I have lost two days trying to solve this nightmare.

any thoughts?

I have uploaded a sample project to here and here

After downloading your sample project, I had it working in a few minutes by making the following changes.

First, you need to add an entry for the MyProject target's Build Settings under Header Search Paths, so that the files such as HelloWorldLayer.h, which #import "cocos2d.h", know where to find that file.

Under the Header Search Paths, I entered ../MyStaticLibrary/MyStaticLibrary/libs/** like shown in the image below:

That solved the problem of the inability of the preprocessor to find the necessary source files from the MyStaticLibrary, for the MyProject project, but after compiling, I got an error about missing symbols. I needed to add the built libMyStaticLibrary.a to the Link Binary With Libraries step like shown in the image below:

After that, the project compiles fine.
