How to code an App that will build QT projects

[locke]

It seems that the OBJECT_DIR is a .pro variable. That means that I need to change the .pro file of all projects that I will build, or it is possible to set that variable in the QProcess or in the qmake as an argument or similar. I havent found anything like that.

Try

C:\Qt\2010.01\qt\qmake\qmake.exe "OBJECT_DIR = C:/testbuild" C:\where\your\project\is\MyProject.pro -spec C:\Qt\2010.01\qt\mkspecs\win32-g++

C:\Qt\2010.01\qt\qmake\qmake.exe "OBJECT_DIR = C:/testbuild" C:\where\your\project\is\MyProject.pro -spec C:\Qt\2010.01\qt\mkspecs\win32-g++

I havent used OBJECT_DIR becasue it only moves the .o files , but not the make files. So I did use QProcess::setWorkingDirectory ( const QString & dir ) before launching the process and I know where the make files are created.

Does it work now?

Yes, it creates the makefile files in a located folder. Im triying now to make the second step, with mingw32-make.

For the next people having the same problem.

Do not use "C:/Qt/2010.01/qt/qmake/qmake.exe"

Use "C:/Qt/2010.01/qt/bin/qmake.exe";

Both qmake will create a different makefile and if you choose the first one, you will have problems to build the project.
