Maybe it is a very simple problem, but i still don't get it!
I have the following situation:
ProjectA and ProjectB
ProjectA is a pure framework and ProjectB should just use this framework.
I just opened the project settings of ProjectB -> dependencies and checked the box of ProjectA.
So far so good. If I build ProjectB, ProjectA compiles first. (Also good!)
BUT: How can I simply use the classes/headers from ProjectA in ProjectB? Is there another way but adding every file of ProjectA in the .pro file of ProjectB???
I used to do that with Eclipse. There u just have to set the dependencies and you can use the classes and headers...
The compiler recognizes the complete files of ProjectA that are required. But Make says smth like: No rule to make target "xxx.cpp" needed by "xxx.o"!
I also tried the SUBDIRS option in the .pro file of ProjectB. No change...
I'm using MinGW if that helps...
Big Thanks in advice!
A standard approach would to build ProjectA as a library (or several libraries), and then add them to ProjectB through standard vars in qmake:
LIBS += yourlib
INCLUDEPATH += yourlibHeaders
And use those libs in ProjectB.
Does yourlibHeaders work recursive?
Because my project consists of sub directories! And then i would have to add all the headers manually...?
The most fool-proof approach is most likely to add a new .pro file using the subdirs template that references your two existing projects. That effectively fuse your two projects into one.
