Application directory path on linux (shortcut)

[MadBear]

Greetings,
I would like to know how to access application directory in linux if I run application through shortcut. QApplication::applicationDirPath(), doesn't give right path.

Regards,
MadBear

Best way may be to use argv[0].

Something like this should work under linux (not handling LONG paths though...):

QString appPath()
{
	// in linux, look up the /proc/<PID>/exe link.
	QString link;
	char spath[128];
	memset(spath,0,128);
	link.sprintf("/proc/%d/exe",getpid());
	if (readlink(link.toUtf8().constData(),spath,128)>0) return spath;
	return "";
}

QString appPath()
{
	// in linux, look up the /proc/<PID>/exe link.
	QString link;
	char spath[128];
	memset(spath,0,128);
	link.sprintf("/proc/%d/exe",getpid());
	if (readlink(link.toUtf8().constData(),spath,128)>0) return spath;
	return "";
}
