Question

我有一个库，我希望它根据我所处的配置（调试或发布）将自身复制到目录。这是我的项目文件。

TARGET = JECLibrary
TEMPLATE = lib

DEFINES += JECLIBRARY_LIBRARY

SOURCES += \
    JECMessageText.cpp \
    JECMessageCombo.cpp \
    JECButton.cpp

HEADERS +=\
        JECLibrary_global.h \
    JECMessageText.h \
    JECMessageCombo.h \
    JECButton.h

CONFIG(debug, debug|release)
{
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/debug)
    message("Copying to Jane Debug Directory.")
}
CONFIG(release, debug|release)
{
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/release)
    message("Copying to Jane Release Directory.")
}

FORMS += \
    JECMessageText.ui \
    JECMessageCombo.ui

由于某种原因，调试或发布DLL被复制到两个目录而不是一个。因此，如果我在发布模式下运行，我会在Debug目录和发布目录中获取发行版DLL。

我完全糊涂了。有人可以对此有所了解吗？感谢

开口支撑应与条件位于同一行：

CONFIG(debug, debug|release) {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/debug)
    message("Copying to Jane Debug Directory.")
}
CONFIG(release, debug|release) {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/release)
    message("Copying to Jane Release Directory.")
}

或

CONFIG(debug, debug|release) {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/debug)
    message("Copying to Jane Debug Directory.")
} else {
    DLLDESTDIR += $$quote(../../../Jane/Jane/Build/release)
    message("Copying to Jane Release Directory.")
}

但是这两条消息都会显示，因为运行qmake时会创建Makefile.Debug和Makefile.Release文件（在Windows上，或者如果你将debug_and_release添加到其他操作系统的CONFIG变量上）。< / p>

Qmake处于发布和调试模式
