[Qt-interest] qmake and staticlib issue

[ami guru]

Hello forum,

Let me elaborate the scenario that i am stuck with

i have the following directories under src/

1.VrMath
2.DataStructs
3.OpenGLRender
4.RaytraceMgr
5.Graphics


I have .pro inside each of the above directories that compiles, creates
static libraries and put them inside lib that reside at the same hierarchy
as src
resides, copies the header files  to the include which also reside at  the
same hierarchy as the src do.


Now some of the directories inside src depends on other directories while
compilation. so i have put them in the INCLUDE path instead of the DEPEND
path. And they compile fine.


I have the error piling up when i am trying to create an application that
uses these libraries that created above. The error are as follows:

**********************************

Which means that the application is finding the .o file.

The .pro file content for the application  is as follows:

***********************************************
TEMPLATE = app
CONFIG += debug_and_release
QT += opengl
TARGET =
DEPENDPATH += .
INCLUDEPATH += .
INCLUDEPATH += ../../include/VrMath
INCLUDEPATH += ../../include/DataStructs
INCLUDEPATH += ../../include/Graphics
INCLUDEPATH += ../../include/OpenglRender
INCLUDEPATH += ../../include/RaytraceMgr


DESTDIR = ../../bin

QMAKE_LIBDIR += ../../lib

# Input
HEADERS += GLWidget.h
SOURCES += GLWidget.cpp main.cpp


CONFIG(debug, debug|release) {
        LIBS += -L -lVrMath -lDataStructs -lGraphics -lRaytraceMgr
    TARGET = RaytraceD
    OBJECTS_DIR = ../../build/Raytrace/Debug
    MOC_DIR = ../../build/Raytrace/Debug
}


CONFIG(release, debug|release) {
        LIBS += -L -lVrMath -lDataStructs -lGraphics -lRaytraceMgr
    TARGET = Raytrace
    OBJECTS_DIR = ../../build/Raytrace/Release
    MOC_DIR = ../../build/Raytrace/Release
    DEFINES+=QT_NO_DEBUG
}

*********************************************************************************
While biulding the static libraries do i have to provide the library path as
well for the libraries that they depend on while building the library?

I have tried that ,but eneded up with  the same error

What am i missing in the process ?


Thanks
