Thiago, Thank you for your reply. We are running the Linux app on a Cray supercomputer. We need this computational power for the problems we are seeking to solve.
Yes, we are ssh'ing into the RHEL 6 sever and forwarding the X11 connection. Our sys admin had to install Qt5 for us to use the app and said that he found the installation difficult. Is there any advice you might have for installing Qt5 to help fix this problem? Many thanks, Bill On sexta-feira, 8 de abril de 2016 18:28:25 PDT [email protected] wrote: Dear Qt Developers, I'm teach a class this quarter at Stanford where the main software package we are using is a Qt5 Linux app running on RHEL 6. Students with Windows or Linux laptops aren't having problems, but students with Macs are. In particular, when the students try to do a copy, they get the error message QXcbClipboard::setMimeData: Cannot set X11 selection owner Why are you running a Linux application on a Mac? Are you ssh'ing into the RHEL 6 server and forwarding the X11 connection? If so, I'd say that the X server that you have on those Mac is rather defective. Instead, I'd recommend you compile the app for Mac and run locally, not on the server. and the copy doesn't work. When they quit the application, they get the additional message QApplication::qAppName: Please instantiate the QApplication object first We need a testcase for this. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
