View Full Version : "No DOS or PE signature found" error when creating a Qt shared library

10th June 2013, 16:02
Dear all,

I am trying to build a Qt library on Windows as explained at http://qt-project.org/wiki/How_to_create_a_library_with_Qt_and_use_it_in_an_a pplication.
I am able to build it correctly, however when checking the obtained .lib file with Dependency Walker, I get the following error: “No DOS or PE signature found. This file is not a valid 32-bit or 64-bit Windows module.”
I am currently searching the web for an explanation but I have not found any clue up to now. I suppose there is something wrong with my setup (I am using Qt 4.8.1, Qtcreator 2.5.0 and Microsoft Visual C++ Compiler 10.0). Would anyone already have encountered a similar issue?

Thanks in advance for any help.

Best regards

What about the obtained dll file?
