在Qt Creator中自动重建依赖关系

问题描述

Qt Creator(4.6.1)让我发疯.我的应用程序分为三个部分:

Qt Creator (4.6.1) is driving me nuts. My application is split into 3 parts:

• 该应用
• 图书馆
• 单元测试应用

当我在库中更改文件并重建应用程序时，编译器不会重新编译该库，而是与该库的旧版本链接.

When I change a file within the library and rebuild the application, the compiler does not recompile the library but links with the old version of the library.

此外，当我更改库，重新编译它然后编译应用程序时，因为它使用了缓存的应用程序，所以没有编译发生.

Also, when I change the library, recompile it and then compile the app, no compilation takes place because it uses the cached app.

是否可以更改设置?这是我的项目文件:

Is there a setting to change that? Here's my project file:

TEMPLATE = subdirs

SUBDIRS += \
    app \
    lib_mylib \
    tests

app.depends = lib_mylib
tests.depends = lib_mylib

该库是作为静态库构建的:

The lib is built as a static library:

TEMPLATE = lib
TARGET = mylib
CONFIG += staticlib

推荐答案

我使用CONFIG + =有序，DEPENDPATH和PRE_TARGETDEPS来解决相同的问题.它适用于Linux和MSVC.试试吧.

I have used CONFIG += ordered, DEPENDPATH and PRE_TARGETDEPS to get rid of the same problems. It works for me on linux and on win with MSVC. Try it.

在您的项目专业文件中添加:

in your project pro file add:

CONFIG += ordered

P.S .:您的lib应该列在第一位.喜欢:

P.S.: your lib should be listed first. Like :

SUBDIRS += \
    lib \
    app \
    tests

在您的exe .pro文件中，使用正确的路径添加它:

in your exe .pro file add this with correct paths:

DEPENDPATH += $$PWD/../lib
PRE_TARGETDEPS += $$OUT_PWD/../lib/liblib.a
