C++ QT creator与mingw、glew链接错误

我已经尝试了大约3/4天将glew与qt creator链接，但我无法做到。 我试过使用msvc和MingW64&32位。 现在我使用的是Mingw32位，也是用mingw编译的32位glew

这是my.pro文件中的代码：

QT       += core gui opengl

CONFIG += c++11

INCLUDEPATH += C:/lib/glew-gcc-debug-1.10.0-win32/include/GL

LIBS += -lglew32.dll -LC:/lib/glew-gcc-debug-1.10.0-win32/bin -LC:/lib/glew-gcc-debug-1.10.0-win32/lib


TARGET = Test
TEMPLATE = app


SOURCES += \
    glslprogram.cpp \
    glutils.cpp \
    main.cpp \
    mainview.cpp \
    mainwindow.cpp \
    sceneLine.cpp \
    dialog.cpp \
    viewpositiondialog.cpp

HEADERS  += \
    glslprogram.h \
    glutils.h \
    mainview.h \
    scene.h \
    mainwindow.h \
    sceneLine.h \
    dialog.h \
    viewpositiondialog.h

FORMS += \
    dialog.ui \
    viewpositiondialog.ui

OTHER_FILES += \
    shader/scenebasic2.dat

这就是输出：

希望有人能帮忙。

你的链接命令行看起来可疑；特别是缺少

-mwindows

，以及指定库的顺序。为什么指定

-lshell32

和

-lmingw32

？这些是默认库；应该让编译器驱动程序自己指定它们。为什么指定

-lglew32.dll

？当然应该是

-lglew32

，（除非您的DLL真的被称为

glew32.DLL.DLL

）。我没有指定shell或mingw库，这只是输出。由于库是glew32.dll.a（使用mingw编译），您需要放置“.dll”以链接它。“我没有指定shell或mingw库，这只是输出。”。这并不意味着它是正确的——它不是（虽然这可能不是关键的；OTOH，库的顺序是）。“因为库是glew32.dll.a（用mingw编译），所以需要放置“.dll”以链接它。“错误！建议你阅读；您告诉它查找

libglew32.dll.dll.a

，

glew32.dll.dll.a

，

libglew32.dll.a

（它可能只是偶然地找到了它，但找不到，因为它应该是一个静态库，而不是dll导入库），

glew32.lib

，

libglew32.dll

，然后是

glew32.dll

，正是按照此搜索顺序。更正我的上一条注释：指定搜索列表中的最后三项（从

-lglew32.dll

展开）应分别为

glew32.dll.lib

、

libglew32.dll.dll

、和

glew32.dll.dll

。
