<![CDATA[Permission denied and Collect2.exe error]]>Hi All,

I'm trying to compile and run a programm and I constantly receive these two error messages.
error: cannot open output file debug\ProjektMockUp.exe: Permission denied
error: collect2.exe: error: ld returned 1 exit status

I really don't know what to do. It started once, crashed, I closed it. I cannot see anything running in the Task Manager, I deactivated my Anti Virus.
Any Idea?
Thanks a lot in advance!

This is what the Compile Output tab provides:

I finally found it!

Reboot didn't work, and I finally figured, that I should not run it in Debug mode rather in Release.

Thanks a lot for your quick help!

Edit: Process Lasso eventually solved it best for me. It consitently showed the falsely running processes and .exe.

But yes, restarting Windows usually helps, too ;)

thanks for the quick reply :)
doesn't work unfortunately.
Windows says it is still running/opened somewhere.. I scrolled through the Task Manager 4 times now and cannot find it :(
