CMake & Qt4 (Q3Support)
Updated: this post is obsolete, go to CMake & Qt4 Modules .
Assumption:
Let assume we have a legacy Qt3 system and has been ported to Qt4 with Q3Support Module successfully. Also we want to CMakify it.
Problem:
After following the instructions that is available on the Internet like QtNode. We MIGHT end up with the following compilation errors:
* Error(1): 'Q3somthing' : No such file or directory
- 'Q3MainWindow': No such file or directory
* Error(2) : 'something' : is not a member of "Qt"
- 'ToolBarDock' : is not a member of 'Qt'
- 'Dock' : is not a member of 'Qt'
Solution:
in CMakeLists.txt
For Error(1) add the following :
# Qt Includes
INCLUDE(${QT_USE_FILE})
INCLUDE_DIRECTORIES(${QT_QT3SUPPORT_INCLUDE_DIR})
For Error(2) add the following:
# Qt Definitions
ADD_DEFINITIONS(${QT_DEFINITIONS})
ADD_DEFINITIONS(-DQT3_SUPPORT)
-DQT3_SUPPORT almost two days to figure it out ending up with reading QT source-code. So I hope this will help you.
Example:
I made example for this purpose also to show the simplicity and the power of CMake as cross-platform make system.
Windows Vista & NMake(VS2008)
Linux & Make(gcc)
Example File: CMakifyQ3S
