call external executable file in Mac OS from QT

zhaobofu

I ‘m trying to call an external executable file in Mac OS using DesktopServices , the executable name is
ABC.x, I can run the executable from Mac OS command line with ./ ABC.x

But cannot find a right way to call the executable from QT, I tried something as following, but it is not working

QProcess *process =new QProcess(this);
QString program="/Users/itadmin/Documents/ABC/ABC.x";
process->start(program,QStringList()<<"");

the executable not launching. (No response) Please help.

@zhaobofu
In principle you have the right code, provided the path is correct.

You will need to look through QProcess docs for code which lets you see errors, like error(), readAllStandardError(), errorOccurred(), and similar.

@zhaobofu Why are you passing empty string as parameter?
Did you check http://doc.qt.io/qt-5/qprocess.html#errorOccurred ?

QProcess more suitable for this. What error your getting when u QProcess?

@Chandras002 yes I tried, but there was no error at all!

@JonB thanks I solved the problem by using QT to call a cs.command file, and cs.command calls the executable file.

QString program="Users/itadmin/Documents/det1/cs.command";
QDesktopServices::openUrl(QUrl("file:///"+program, QUrl::TolerantMode));
