在windows下用Qt Creater 编译qwt5.2.1

下载QWT的源码，这里我们下载的版本为qwt-5.2.1，然后解压到一个英文路径下。修改其主目录下的qwtconfig.pri文件（这里所做的修改主要是为了能够调试qwt程序）：将 
else {
    # Qt 4
    win32 {
        # On Windows you can't mix release and debug libraries.
        # The designer is built in release mode. If you like to use it
        # you need a release version. For your own application development you
        # might need a debug version. 
        # Enable debug_and_release + build_all if you want to build both.

        CONFIG           += release     # release/debug/debug_and_release
        #CONFIG           += debug_and_release
        #CONFIG           += build_all
    }
    else {
        CONFIG           += release     # release/debug
    }
} 
修改成为 
    else {
    # Qt 4
    win32 {
        # On Windows you can't mix release and debug libraries.
        # The designer is built in release mode. If you like to use it
        # you need a release version. For your own application development you
        # might need a debug version. 
        # Enable debug_and_release + build_all if you want to build both.

        #CONFIG           += release     # release/debug/debug_and_release
        #CONFIG           += debug_and_release
        CONFIG           += build_all
    }
    else {
        CONFIG           += release     # release/debug
    }
}

使用QT Creator打开解压后的qwt.pro工程文件,点击编译按钮，让QT Creator完成所有的工作。

编译完成后，将源码目录下的qwtd5.dll,qwt5.dll（在qwt-5.2.1/lib）拷到QT SDK的bin目录下（在C:/Qt/2010.02.1/qt/bin），将相应的libqwtd5.a,libqwt5.a拷到lib目录下（在C:/Qt/2010.02.1/qt/lib）。最后将源码（qwt-5.2.1/designer/plugins/designer）目录中libqwt_designer_plugind5.a文件和qwt_designer_plugind5.dll和libqwt_designer_plugin5.a文件和qwt_designer_plugin5.dll文件拷到QT SDK的designer目录下（在C:/Qt/2010.02.1/qt/plugins/designer）。 
      自己在C:/Qt/2010.02.1/qt/include目录下创建一个文件夹qwt， 将源码src目录下的（在qwt-5.2.1/src）所有*.h文件拷到这个文件夹中。 
当创建使用QWT库的QT程序时，将下面两句话添加到.pro文件中： 
LIBS += -L”C:/Qt/2010.02.1/qt/lib” -lqwtd5 
INCLUDEPATH += C:/Qt/2010.02.1/qt/include/qwt 
      但是这时我们还不能在QT Designer中看到qwt部件，这时由于先前下载的QT Creator是用MSVC编译的，所以我们需要重新下载一个QT Creator的源码包，用现有的QT Creator将其编译，以后我们使用编译过的QT Creator即可。 
     接下来还会在linux下编译和QTE平台下去编译。
