QT 版本：qt-sdk-win-opensource-2010.04。
添加环境变量：QMAKESPEC=win32-g++，win32-g++文件夹下的qmake.conf保持默认，QMAKE_LFLAGS = -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc。
生成Makefile和编译：
C:\examples\chap01\hello>qmake -project
C:\examples\chap01\hello>qmake
C:\examples\chap01\hello>mingw32-make.exe release
mingw32-make.exe -f Makefile.Release
mingw32-make.exe[1]: Entering directory `C:/examples/chap01/hello'
g++ -c -O2 -frtti -fexceptions -mthreads -Wall -DUNICODE -DQT_LARGEFILE_SUPPORT

mingw32-make.exe[1]: Leaving directory `C:/examples/chap01/hello'
但是运行MinGW编译的可执行文件，运行时会提示缺少MSVCP80.dll呢，好像我没有用到MS的编译器啊，这是为啥啊，大侠们帮帮忙啊？
