如何在QT5中从qmake的`make uninstall`中运行自定义命令？

Question

我有一个QT项目,在运行时为系统安装服务make install.该.pro文件的相关部分如下:

init.path = /etc/init.d/
init.files = myservicename

updaterc.path = /etc/init.d/
updaterc.extra = chmod 755 $$init.files; \
                 update-rc.d $$init.files defaults 97 03; \
                 service $$init.files start

INSTALLS += target ... init updaterc

这将正确安装服务,然后启动它.

但是,当我运行时make uninstall,虽然已正确删除已安装的文件,但该服务仍保持安装并正在运行.我想在运行时停止和卸载服务make uninstall.

停止和卸载服务的命令如下:

sudo service myservicename stop
sudo update-rc.d -f myservicename remove

但我无法弄清楚如何将上述命令集成到.pro文件中,以便qmake能够理解它们并在Makefile中创建相关规则.

我在这个主题上找到的唯一文档是这样的:http://doc.qt.io/qt-5/qmake-advanced-usage.html,但它没有提到有关卸载的任何内容.

尝试使用.uninstall命令.

mytarget2.path = ~/Documents/inst
mytarget2.target = test.txt
mytarget2.commands = @echo "custom command"
mytarget2.uninstall = @echo "uninstall" 
INSTALLS += mytarget2

它会生成这个makefile:

   ####### Install

install_mytarget2: first FORCE
    @test -d $(INSTALL_ROOT)/Users/mac/Documents/inst || mkdir -p $(INSTALL_ROOT)/Users/mac/Documents/inst
    @echo custom command

uninstall_mytarget2: FORCE
    @echo uninstall
    -$(DEL_DIR) $(INSTALL_ROOT)/Users/mac/Documents/inst/ 


install:  install_mytarget2  FORCE

uninstall: uninstall_mytarget2   FORCE

FORCE:
