VS2019+QT代码与QtCreator工程的互相转换

QT Creator的project转换成Visual Studio的project

在windows10下,运行Qt Command Prompt。

输入命令行:

qmake -tp vc XXX.pro

会生成文件XXX.vcxproj


Visual Studio的project转成QT Creator的project
第一步,因为原Visual Studio工程就是基于QT Template的工程,所以我们可以用VS里的QT插件里的"Create basic .pro file..."菜单选项来自动生成一个.pro文件,实际上,不仅仅生成了.pro 文件,还生成了.pri文件。但是目前的.pro文件还是不能用的,因为其中还有大量的配置需要修改,比如INCLUDEPATH和LIBS.

第二步,修改.pro文件使其包含正确而必要的配置信息。
总结笔者对.pro文件的具体修改如下:
1. TEMPLATE = lib
2. 将DESTDIR =  xxx改成:
    Release:DESTDIR = xxx/Release
    Debug:DESTDIR = xxx/Debug
3. CONFIG += debug_and_release
4. 完善INCLUDEPATH
5. 完善DEPENDPATH (这里又有故事了:事后笔者发现,只要在LIBS里写了-L"<LIBPATH>",就没必要写DEPENDPATH了。)
6. 加上 Release:DEPENDPATH 和 Debug:DEPENDPATH
7. 类似的,完善LIBS,添加Release:LIBS和Debug:LIBS

第三步,双击改好的.pro文件,QT Creator打开此工程,选中合适的Kit,就可以build了。因为是64位机器,Kit选的是QT 5.4.1的msvc2017_64.
最后千万要注意的是,在系统环境变量%PATH%里,对于Visual Studio的编译器cl.exe和链接器link.exe, 要选对路径。比如,对于64位的机器,路径 C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64 应该被加到%PATH%中,而不是 C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin 这一条在前一篇博文中已有详细阐述。

以上步骤做完后,就可以顺利地在QT Creator中进行build了。
最后还要提醒的一点是,如果更改了.pro文件,想让更改生效,必须手动删除qmake生成的Makefile, Makefile.Debug和Makefile.Release文件。
