Visual studio 2015 qMake：如何在C++；

我试图在qMake*.pro文件中指定变量，以便在实际代码（VS 2015项目）中使用宏

我确实有这样的工作示例：

DEFINES += COPYRIGHT_STRING="\"$${QMAKE_TARGET_COPYRIGHT}\""
DEFINES += VERSION_STRING="\"$${QMAKE_TARGET_PRODUCT} $${VERSION}\""

我还需要字符串

3.4

的宏。我尝试了不同的版本写下来，但我总是得到以下错误

RC : fatal error RC1107: invalid usage; use RC /? for Help

我尝试了以下几种变体，可能还有一两种我不记得了

DEFINES += "LATEST_PROCESSABLE_VERSION=3.4"
DEFINES += LATEST_PROCESSABLE_VERSION=\"3.4\"
DEFINES += LATEST_PROCESSABLE_VERSION="\"3.4\""
DEFINES += LATEST_PROCESSABLE_VERSION=\\\"3.4\\\"

如果省略定义变量

LATEST\u PROCESSABLE\u VERSION

的那一行，那么一切都可以正常编译（包括上面的工作示例）

我的文件通常如下所示：

win32:TEMPLATE = vcapp
!win32:TEMPLATE = app

QT += core xml network
CONFIG += console
CONFIG += no_keywords

#C++ exception specification ignored except to indicate a function is not __declspec(nothrow)
QMAKE_CXXFLAGS += /wd4290

VERSION = 3.2.0.3

QMAKE_TARGET_COMPANY = APP GMBH

QMAKE_TARGET_PRODUCT = Fancy Application

QMAKE_TARGET_DESCRIPTION = Does fancy stuff

QMAKE_TARGET_COPYRIGHT = COPYRIGHT (C) $${QMAKE_TARGET_COMPANY} 2018 - ALL RIGHTS RESERVED - FOR INTERNAL USE ONLY

DEFINES += DECODER_COPYRIGHT_STRING="\"$${QMAKE_TARGET_COPYRIGHT}\""
DEFINES += DECODER_VERSION_STRING="\"$${QMAKE_TARGET_PRODUCT} $${VERSION}\""
DEFINES += LATEST_PROCESSABLE_VERSION="\"3.4\""

# set application icon
RC_ICONS = Application.ico

INCLUDEPATH += ../FancyInclude
# ... more includes ...

HEADERS += fancy.h \
# ... many headers ...

SOURCES += main.cpp \
    fancy.cpp \
# ... many sources ...

contains(DEFINES, APP_ARCH_x32) {
    DESTDIR = ../../product/win32
    CONFIG(debug, debug|release) {
        OBJECTS_DIR = ./debug_x86
        MOC_DIR = ./debug_x86
        LIBS += -L../addon/Fab/Bin32 -llibfab32D
        TARGET = FancyApp32D
    } else {
        OBJECTS_DIR = ./release_x86
        MOC_DIR = ./release_x86
        QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO
        QMAKE_LFLAGS_RELEASE = $$QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO
        LIBS += -L../addon/Fab/Bin32 -llibfab32D
        TARGET = FancyApp32
    }
}

contains(DEFINES, APP_ARCH_x64) {
    DESTDIR = ../../product/win64
    CONFIG(debug, debug|release) {
        OBJECTS_DIR = ./debug_x64
        MOC_DIR = ./debug_x64
        LIBS += -L../addon/Fab/Bin64 -llibfab64D
        TARGET = FancyApp64D
    } else {
        OBJECTS_DIR = ./release_x64
        MOC_DIR = ./release_x64
        QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO
        QMAKE_LFLAGS_RELEASE = $$QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO
        LIBS += -L../addon/Fab/Bin64 -llibfab64D
        TARGET = FancyApp64
    }
}

DEFINES += LATEST_PROCESSABLE_VERSION=\\\"3.4\\\"

在一次密集的谷歌搜索之后，我现在已经没有办法尝试了。有人能帮忙吗

编辑1:

至少我认为我有这些例子在顶部工作了一次。但我现在甚至无法让它们工作（再次），我完全不知道是什么导致了这里的错误。我什么都不知道了，请帮帮我！--

编辑2:

好吧，天气热得让我很难受。实际问题是

QMAKE\u TARGET\u COMPANY

和

QMAKE\u TARGET\u PRODUCT

中的空格。下面的示例现在运行良好

...
QMAKE_TARGET_COMPANY = Test GmbH

QMAKE_TARGET_PRODUCT = Fancy Application

QMAKE_TARGET_DESCRIPTION = Does fancy stuff

QMAKE_TARGET_COPYRIGHT = 2018

DEFINES += COPYRIGHT_STRING="\"$${QMAKE_TARGET_COPYRIGHT}\""

DEFINES += VERSION_STRING="\"$${VERSION}\""

DEFINES += LATEST_DECODABLE_ESF_VERSION="\"3.4\""    
...

我想

…使用

QMAKE\u TARGET\u COPYRIGHT

中的空格，以获得

COPYRIGHT（C）$${QMAKE\u TARGET\u COMPANY}2018的价值-保留所有权利-仅供内部使用

我想

…定义另一个变量

APP\u NAME\u和\u VERSION\u STRING

，由

$${QMAKE\u TARGET\u PRODUCT}

和

$${VERSION}

组成，用空格分隔

我怎样才能做到这一点？我没有找到任何使它工作的方法。

请记住，文本必须转义两次：对于

qmake

本身和shell命令。所以正确的逃逸应该是这样的：

win32:TEMPLATE = vcapp
!win32:TEMPLATE = app

QT += core xml network
CONFIG += console
CONFIG += no_keywords

#C++ exception specification ignored except to indicate a function is not __declspec(nothrow)
QMAKE_CXXFLAGS += /wd4290

VERSION = 3.2.0.3

QMAKE_TARGET_COMPANY = APP GMBH

QMAKE_TARGET_PRODUCT = Fancy Application

QMAKE_TARGET_DESCRIPTION = Does fancy stuff

QMAKE_TARGET_COPYRIGHT = COPYRIGHT (C) $${QMAKE_TARGET_COMPANY} 2018 - ALL RIGHTS RESERVED - FOR INTERNAL USE ONLY

DEFINES += DECODER_COPYRIGHT_STRING="\"$${QMAKE_TARGET_COPYRIGHT}\""
DEFINES += DECODER_VERSION_STRING="\"$${QMAKE_TARGET_PRODUCT} $${VERSION}\""
DEFINES += LATEST_PROCESSABLE_VERSION="\"3.4\""

# set application icon
RC_ICONS = Application.ico

INCLUDEPATH += ../FancyInclude
# ... more includes ...

HEADERS += fancy.h \
# ... many headers ...

SOURCES += main.cpp \
    fancy.cpp \
# ... many sources ...

contains(DEFINES, APP_ARCH_x32) {
    DESTDIR = ../../product/win32
    CONFIG(debug, debug|release) {
        OBJECTS_DIR = ./debug_x86
        MOC_DIR = ./debug_x86
        LIBS += -L../addon/Fab/Bin32 -llibfab32D
        TARGET = FancyApp32D
    } else {
        OBJECTS_DIR = ./release_x86
        MOC_DIR = ./release_x86
        QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO
        QMAKE_LFLAGS_RELEASE = $$QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO
        LIBS += -L../addon/Fab/Bin32 -llibfab32D
        TARGET = FancyApp32
    }
}

contains(DEFINES, APP_ARCH_x64) {
    DESTDIR = ../../product/win64
    CONFIG(debug, debug|release) {
        OBJECTS_DIR = ./debug_x64
        MOC_DIR = ./debug_x64
        LIBS += -L../addon/Fab/Bin64 -llibfab64D
        TARGET = FancyApp64D
    } else {
        OBJECTS_DIR = ./release_x64
        MOC_DIR = ./release_x64
        QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO
        QMAKE_LFLAGS_RELEASE = $$QMAKE_LFLAGS_RELEASE_WITH_DEBUGINFO
        LIBS += -L../addon/Fab/Bin64 -llibfab64D
        TARGET = FancyApp64
    }
}

DEFINES += LATEST_PROCESSABLE_VERSION=\\\"3.4\\\"

及

请注意，字符串中的所有空格都必须转义

您也可以切换到使用

QMAKE_替换

来自动生成适当的C头文件，并避免丑陋的命令行

定义

谢谢您的帮助，mate，但我仍然有问题。你对

最新可处理版本的第一个建议很好，但我无法让第二个起作用。如果我这样做，我会得到错误
moc:指定的输入文件太多：'Decoder''BETA\''3.2.0.3'
。此外，正如您所看到的，转义空间不是一个空间，而是添加到字符串中的'\'（你最近建议使用
QMAKE_替代品
，这让我很开心！我不知道这种可能性，我找到了一个很好的解释。谢谢你，伙计！
