Hi Handi,

I am getting the same error. i am wondering if you have overcome the problem. If so please let me know the solution.

What error? The only thing mentioned above is that something "can't find any of those files" or "it doesn't work." An actual error message would be quite helpful, but I don't see any. At a minimum, it would illuminate whether the problem is an inability to locate the header files or the library files.

To quote and repair an earlier answer in this thread.

At compile time:

• Use INCLUDEPATH to define extra locations to be searched for header files
• Use LIBS -L options to define extra locations to be searched for libraries
• Use LIBS -l options to name the libs to be used.

Example:

INCLUDEPATH += /home/me/foo/include
LIBS += -L/home/me/foo/lib -lfoo

INCLUDEPATH += /home/me/foo/include
LIBS += -L/home/me/foo/lib -lfoo

At run time the dynamically loadable libraries must be locatable by the operating system:

• On Windows: In the current working directory of the executing process (note that this is rarely the same as the source code directory) or on the system PATH.
• On Linux: In directories listed in the LD_LIBRARY_PATH environment variable (if it exists) and on the system library path (see /etc/ld.so.conf). See man ld.so for other, less used options.
• On Mac OS X: Probably similar to Linux but bound to be different in detail.
