在 make 时间获取 Qt qmake 项目上的 git commit id

Question

On Windows 10 Qt 5.15, I'm getting git commit id on Qt qmake project at qmake time with

COMMIT = '\\"$$system(git rev-parse --verify master)\\"'
DEFINES += COMMIT_VERSION=\"$${COMMIT}\"

And on main.cpp I can print that with qDebug() << COMMIT_VERSION;

Since some commits do not require a full project rebuild I'm getting old (not the latest) commit ids.

How can I get that updated on every build?

I use Ubuntu but for doing what you want I try this:

what you do is like in cmd or terminal always type this command :

git rev-parse --verify master

so for doing this I use QProcess like this:

first of all, I create one bash file and put that command there. I always put commands in one shell script file because it's easy and just put .sh file in the start process.

test.sh

#!/bin/sh
cd /home/parisa/projectFolderName;git rev-parse --verify master

and this is code:

QProcess *myProcess = new QProcess();

myProcess->start("/home/parisa/untitled1/test.sh");
myProcess->waitForFinished(3);

QString  str = myProcess->readAll();
qDebug() << "git id  : " << str;
delete myProcess;

and this is the output:

In QTCreator short cut Alt + K or Alt + G will show you the git log.
