Command working in terminal but not via QProcess

keytooker

I am currently using macOS Sierra and QT 5.8. This command

git rev-list --count branchname

is working when executed via terminal. But not via QProcess.
My sample code is

QSharedPointer<QProcess> proc(new QProcess);
proc->start("git", QStringList() << "rev-list" << "--count" << "branchname");
proc->waitForFinished();
QByteArray output = proc->readAll();
proc->close();
qDebug() << output;

So, after execute the code above, the console output is empty.

What might be the problem?

@keytooker Rough guess. Which folder is it executing in? Run the "pwd" command to find out.

QProcess

Hi
Hook up error handler and see what it reports

connect(proc, &QProcess::errorOccurred, [=](QProcess::ProcessError error) 
{ 
    qDebug() << "error enum val = " << error << endl; 
});

@matthew.kuiash Thank you for your hint! Shadow build is "on" in my project . Therefore the git-command was executed in other directory. I have corrected my code here so:

auto oldPath = QDir::currentPath();
QString sourcePath = QStringLiteral("/Users/user_name/project_source_directory");

if (QDir::setCurrent(sourcePath))
{
    proc->start("git", QStringList() << "rev-list" << "--count" << "branch_name");
    proc->waitForFinished();
    QByteArray output = proc->readAll();
    proc->close();
    qDebug() << output;
}
QDir::setCurrent(oldPath);
