3rd Part library do not compile with Qt Creator...

[belimawr]

Hi,

I am using a 3rd Party library GBDI Arboretum (http://gbdi.icmc.usp.br/arboretum) in a Qt with OpenGL project. For a time it worked well, but now I need to add some .cpp files and when I compile the project I receive thousands errors like: "multiple definition of" some function....

I am following an example which uses the same includes, and this example works very well. However this example is not a Qt project, it is only a .cpp file that I compile using: @g++ -I ./arboretum/include/ -I ./arboretum/src/ main-app.cpp@

So, the problem is not in fact that I have included some .cpp, it is something that Qt is doing...

I added the INCLUDEPATH in .pro file:
@INCLUDEPATH += ./arboretum/include/
./arboretum/src/@

Qt can find the library files, but can not compile it correctly.

I tried everything which I found in Qt help, but nothing worked for me...

To make sure that the problem is in Qt, I did a test using Netbeans and the same arboretum library and includes. To compile I only had to do was add "arboretum/src" and "arboretum/include" in the include path and it worked well.

Once again, the problem seems be only in Qt...

Does anyone have any suggestion?

What are the actual error messages? Are they from the compiler or the linker?

I think they are from compiler here is an example:
@g++ -Wl,-O1 -o Simulador_de_Particulas main.o janelaprincipal.o opengl.o trackball.o fastareader.o clusterclass.o moc_janelaprincipal.o moc_opengl.o qrc_shader.o -L/usr/lib -L/usr/X11R6/lib -lQtOpenGL -lQtGui -lQtCore -lGLU -lGL -lpthread

and they continue for thousands of lines...
