在 Qt 中包含 .pro 文件? [英] Include a .pro file in Qt?

问题描述

我有一个项目，它有很多包含路径、源文件和头文件.该项目作为一个独立的应用程序运行(它不是一个库).

I have a project which has lots of includepaths, source and header files. The project is run as a standalone application (it's not a library).

我想为该应用程序的新功能实施测试(Qt 单元测试框架)，为此，我需要(应用程序)项目的包含、源代码和头文件在(测试)项目中可用.

I would like to implement tests (Qt unit test framework) for new features for that application and for that, I require the includes, sources and header files of the (application) project to be available in the (testing) project.

我尝试将以下内容放入测试项目 .pro 文件中:

I have tried putting the following in the testing project .pro file:

include(../application/app.pro)     #app.pro is the application project

然而，首先它会抱怨 main.cpp，如果我注释掉，就会出现解析错误.(评论 main.cpp 很糟糕，因为我正在更改主项目以便测试能够编译)

However first it complains about main.cpp, and if I comment that out there is a parsing error. (commenting main.cpp is bad since I'm changing the main project just so that the testing will compile)

我可以通过手动复制(应用程序)项目中的所有包含路径、源和头字段来获得我想要的行为，但我正在寻找一种更简洁的方法.

I can get the behavior i want by manually copying all the includepath's, source and header fields from the (application) project but am looking for a cleaner way.

执行此操作的最佳方法是什么?是否可以轻松地将一个 .pro 包含到另一个中?

What would be the optimal way to do this? Is it possible to painlessly include one .pro into another?

推荐答案

您应该进行两个修改:

1. 将所有头文件和特定于构建的设置分离到一个 *.pri 文件中.这是您需要的，而不是包含 *.pro.
2. 将所有业务逻辑移到一个库中，以便能够在单独的项目中对其进行测试.

例如，您将拥有 build.pri:

E.g., you will have build.pri:

# build.pri
TOPDIR = $$PWD
INCLUDEPATH += . \
               $$TOPDIR/include

DEPENDPATH += $$TOPDIR

INCLUDEPATH += $$TOPDIR/additional/libararies

HEADERS += all.h \
           your.h \
           headers.h \
           of.h \
           interest.h

QT      += xml
# etc., etc.

和 core.pro

# core.pro
TEMPLATE = lib

CONFIG  += dll thread create_prl
QT      += network xml xmlpatterns sql

include(../build.pri)

HEADERS  += \
            headers.h

SOURCES  += sources.cpp \
            many_of_them.cpp

TARGET     = core
# etc., etc.

(注意include(../build.pri))，然后将你的主项目app.pro 作为subdirs项目以 core 和 gui 作为应用程序的组件，test.pro 具有强制性的 core 和尽可能多的测试你想要.

(note the include(../build.pri)), and then make your main project app.pro as a subdirs project with core and gui as components of application, and test.pro with obligative core and as many tests as you want.
