Problems solved while Making CPP app work on eclipse CDT with cygwin

On Windows.
Using libsndfile to decode wav file to raw pcm.

Problem1: Linking to the external library  libsndfile.
Extracting/installing libsndfile gave me the header and DLL.

In Eclipse, Set [Project->Properties->C/C++ General->"Paths and Symbols"->include] and  [Libraries] to the .h and .dll files respectively.(F:\libsnd\includes\libsndfile-1.h and F:\libsnd\libsndfile-1.dll)
Result: While linking "File not found: libsndfile-1.h"

Solution:
Added folder containing libsndfile-1.dll (F:\libsnd\) to [Project->Properties->C/C++ General->"Paths and Symbols"->Library Paths] and added "sndfile-1" to [Libraries] {"libsndfile-1.dll" - ["lib", ".dll"]}

Solved.

Problem2: Now EXE is generated but on "Run" throws "multiple target patterns. Stop." in some ".d" file

http://dev.eclipse.org/newslists/news.eclipse.tools.cdt/msg12202.html : The ":" in path to header file is detected as a new target.

Solution: 

Changed "F:\libsnd\includes\libsndfile-1.h" to "/cygdrive/f/libsnd/includes/libsndfile-1.h" in [Project->Properties->C/C++ General->"Paths and Symbols"->include]

Solved.

Problem3: While debugging it says "gdb unknown target exception"

Solution: http://wiki.eclipse.org/CDT/User/FAQ#I_get_the_message_.22gdb:_unknown_target_exception_0xc0000135_at_0x7c9766c6.22

Add path to DLL file in environment variable "PATH". Restart eclipse.

Or Copy the dll to the project folder

Tried editing the path variable.

Solved.
