Question

我有几个相互依赖的Qt项目。两个项目构建具有不同目的的可执行文件（即我的主应用程序和单元测试）并依赖于相同的库。但是，在构建单元测试时，需要使用不同的编译器设置编译这些库。因此，假设我的应用程序需要一组编译器标志，并且在编译库时这组标志也应该是默认值。我的单元测试应用程序需要另一组（或仅一组）编译器标志，以便在编译它们时设置库。

如何编写qmake *.pro文件，以便我可以运行qmake一次，然后使用生成的makefile在不同的make运行中为两个应用程序编译库？我正在考虑将默认的制作目标debug和release与'默认'标记以及为我的单元测试构建的额外目标test，但我似乎无法弄清楚如何做这个。我坚持使用Qt 4.8。

一些背景：我使用C ++编程，需要为库中定义的类创建一些模拟对象。但是，这些类不包含virtual方法，因此我添加了一个预处理程序标志，在编译单元测试时定义为virtual，否则为空。这样我可以覆盖模拟对象中的方法，但不会在发布版本中遇到虚函数调用的开销。

可能我的解决方案适合您。我使用make-file创建我的divert pro-Files。在项目树中创建程序的示例：首先是一个适合程序的简单makefile：

SHELL = /bin/bash

BUILD_PATH  := $(shell cd ../../../; pwd)
CONF_PATH   := $(BUILD_PATH)/sources/config
BIN_PATH    := $(BUILD_PATH)/bin
LIB_PATH    := $(BUILD_PATH)/lib
INS_PATH    := /usr/local

MODULES     := core gui widgets printsupport
TARGET      := CCDDataDisplay
TEMPLATE    := app

DEFINES     := 

INCLUDES    := $(BUILD_PATH)/sources/include
LIBS        := -L$(LIB_PATH) -lhrlLib

DESTDIR     := $(BIN_PATH)

MOCS        := MainWindow.h

include $(CONF_PATH)/conf_qmake.mk

conf_qmake.mk：

QMAKE       := qmake-qt5

HEADERS     := $(wildcard *.h)
C_SOURCES   := $(wildcard *.c)
CPP_SOURCES := $(wildcard *.cpp)

SOURCES := $(C_SOURCES)
SOURCES += $(CPP_SOURCES)
FORMS   := $(wildcard *.ui)

.PHONY: all
all: depdirs
    @echo  -e  "\n\x1b[32;01m Building \x1b[34;01m$(TARGET)\x1b[32;01m in $(shell pwd) ... \x1b[0m"
    @if [ ! -d .build ]; \
    then \
        rm -f qmake.pro; \
        cp $(CONF_PATH)/qmake.pro qmake.pro;\
        mkdir -p .build; \
        cd .build; \
        $(QMAKE) -makefile "MODULES_IN=$(MODULES)" \
        "TARGET_IN=$(TARGET)" \
        "TEMPLATE_IN=$(TEMPLATE)" \
        "DEFINES_IN=$(DEFINES)" \
        "INCLUDES_IN=$(INCLUDES)" \
        "LIBS_IN=$(LIBS)" \
        "DESTDIR_IN=$(DESTDIR)" \
        "SOURCES_IN=$(SOURCES)" \
        "MOCS=$(MOCS)" \
        "FORMS_IN=$(FORMS)" \
        ../qmake.pro >> /dev/null; \
    fi;
    @$(MAKE) -s -C .build;

.PHONY: depdirs
depdirs:
    @$(foreach dir, $(DEPDIRS), $(MAKE) -s -C $(dir);)

.PHONY: install
install:
    @$(MAKE) -s -C .build install;

.PHONY: realclean clean distclean
clean:
    @if [ -d .build ]; then $(MAKE) -s -C .build clean; fi
    @$(RM) *~;
    @$(RM) $$(BUILD_PATH)/include/*~;

realclean:
    @$(RM) -r .build;
    @$(RM) qmake.pro;
    @$(RM) *~;
    @$(RM) $(BUILD_PATH)/include/*~;

distclean: realclean
    @$(RM) $(BUILD_PATH)/bin/$(TARGET);
    @$(RM) $(BUILD_PATH)/lib/lib$(TARGET)*;

和最后一次qmake.pro：

QT  += $$MODULES_IN

TARGET = $$TARGET_IN
TEMPLATE = $$TEMPLATE_IN

CONFIG += staticlib

DEFINES += $$DEFINES_IN

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
INCLUDEPATH += $$INCLUDES_IN

LIBS += $$LIBS_IN

DESTDIR = $$DESTDIR_IN

SOURCES += $$SOURCES_IN

HEADERS += $$MOCS

FORMS += $$FORMS_IN

unix {
    target.path = /usr/local
    INSTALLS += target
}

有了这个我只有安静的简单makefile用于生成。整个项目构建是在一个makefile上完成的项目树。

也许这有帮助...

在qmake中添加了编译器选项的附加makefile目标
