Get executable path on linux

[hbatalha]

My app uses a custom build of ffmpeg that I keep the in the app install location so it doesn't conflicts with the official ffmpeg in case user has it in his machine.

I want to get its install location and for that I use, like in Windows, QString QDir::currentPath() but the problem I am facing is that I am installing the program through a deb package and so by my tests QDir::currentPath() will point to the location of the deb file since it is the parent of my app executable because deb installation creates a symbolic link of the my app executable to /usr/bin/ .

Right now I install my app in /opt/my_app_name/ and I could set current path there but, even though unlikely. the user might change that location and I need to know where my executable is so I can determine the ffmpeg location and avoid errors.

I hope I made myself clear.

QDir::currentPath() is not the location of the application, it is the running application's current working directory. This, even on Windows, can be anywhere.

QCoreApplication::applicationDirPath() is your best bet.
