Qt Creator+MinGW+OpenCV2.3.1 开发环境搭建(windows 7 系统)
毕设需要的windows下开发环境。QT+opncv+openGL(QTSDK已经包含)
接下来还要在RHEL6.2下配置,还要配置交叉编译,好头疼,一步步来吧,看来加个群多问问还是有好处的。
1.必备软件:
Qt SDK for Open Source C++ development on Windows:http://qt.nokia.com/downloads/sdk-windows-cpp-offline
QT开发所必需的全部资源都在这里了
OpenCV-2.3.1-win-superpack:http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.3.1/
目前最新的OpenCV版本,里面有源码和编译好的各版本的DLL和LIB,以防万一,还是自己编译吧
cmake-2.8.5-win32-x86:http://www.cmake.org/cmake/resources/software.html
编译OpenCV要用到。
2.安装软件
安装Qt SDK,第一次选择default安装,装了很久,装完后用Qt Creator打开QT 测试程序,会出现目标设置的对话框,发现只有塞班设备可选,我本来是要做桌面开发的,找不到桌面选项。自己也不会调整。果断卸载重装,选择custom,把塞班开发相关的选项去掉,这样安装也会快很多,装完后用Qt Creator再次打开QT 测试程序。出现:
选择桌面(选择Qt模拟器也能运行,出来的是个塞班手机模拟器),即可运行测试程序。
不需要什么特别的配置,因为安装SDK的时候Qt Creator已经配置好了。如下图,有两个编译器可以选择,MSVC2008和MinGW4.4
这里选择MinGW4.4,因为下面的OpenCV使用MinGW4.4编译。 把 “<Qt_directory>/mingw/bin” 添加到环境变量PATH中。
安装OpenCV,将OpenCV-2.3.1-win-superpack.exe解压至全英文不带空格的路径里面(<OpenCV_directory>)。目录下build文件夹里应该是编译好的东西,暂时不用,其他是源码自己编译呗。
安装cmake-2.8.5-win32-x86.exe。生成makefile用的
3.编译OpenCV
然后下面的步骤参考了别的文章:
Steps to build OpenCV with Qt Creator and MinGW
1. Run CMake GUI.
2. Set the source code: “<OpenCV_directory>”
3. Set where to build binaries to: “<build_directory>”. Example: E:\OpenCV-2.3.1\MinGW
4. Press Configure
5. Let CMake create the new folder.
6. Specify the generator: MinGW Makefiles.
7. Select “Specify Native Compilers” and click Next.
8. For C set: “<Qt_directory>/mingw/bin/gcc.exe”
9. For C++ set: “<Qt_directory>/mingw/bin/g++.exe”
10. Click Finish
11. In the configuration screen type in “DEBUG” (or “RELEASE” if you want to build a release version) for CMAKE_BUILD_TYPE. Check BUILD_EXAMPLES if you want. Check WITH_QT .Uncheck WITH_QT.
12. Click configure again.
13. The configure screen will make you specify the qmake path. It is in the Qt directory: “<Qt_directory>/qt/bin/qmake.exe”
14. Click configure again. Click generate. Close CMake.
15. Go to the command prompt and go to the folder where you built your binaries (command: cd <build_directory>) and type “mingw32-make” and hit enter (this might take some time).
16. Then type “mingw32-make install” and hit enter again
等待编译,结束后需要的东西都在install文件夹里面了。把<build_directory>\install\bin添加到环境变量PATH里面吧。例如E:\OpenCV-2.3.1\MinGW\install\bin
重新启动。没重启没添加这个环境变量前,Qt Creator配置好后运行OpenCV -QT测试程序会出错。
4.Qt Creator配置OpenCV
只需要修改.pro文件,添加include和lib。例如
INCLUDEPATH+=E:\OpenCV-2.3.1\MinGW\install\include
INCLUDEPATH+=E:\OpenCV-2.3.1\MinGW\install\include\opencv
LIBS+=E:\OpenCV-2.3.1\MinGW\install\lib\libopencv_core231d.dll.a
LIBS+=E:\OpenCV-2.3.1\MinGW\install\lib\libopencv_highgui231d.dll.a
LIBS+=E:\OpenCV-2.3.1\MinGW\install\lib\libopencv_imgproc231d.dll.a
然后下面就没什么问题了吧。运行下测试程序吧:
