Yeah i feel like i do sudo apt-get update && upgrade at least once a day. I just checked about SIP and i compiled it from source but i cant remember if i actually used the command make and make install. Does that mean i have to reinstall pyqt5 again? I guess i just open a new thread. Thanks for all the help @SGaist
@Chris-Kawa Thank you, now it works. The solution was simple, but apparently I must understand better how the paths work. If you have any advice on where to start reading or you know any interesting online article/tutorial, please tell me :-)
dll paths do not influence the build so they are not included in qmake. if you use QtCreator in the right bar select project and in the build and run tab, select the run subtab and you can customise the run environment adding the paths of the dlls to the run environment PATH
otherwise you can use the INSTALLS of qmake to deploy all the binaries where you need them
I think, that it is hardly related to the OpenCV lib, as this problem does not occur when using this library in Microsoft Visual C++ Express 2010. The main reason I do not use MinGW - as OpenCV library contain files for VS2010 (the version of the library I use - is 2.4.9 - with the support of VS2010).
The version of Qt - 5.4.2/5.5.0 that support MSVC 2010.
@Chris-Kawa thank you for your response! I know that there is no 64bit VS, and you are right about the 64 bit builds, I just don't know how to do it :) I managed to get rid of the problem written above by removing qtmain.lib from the lib listing, and VS builds the app succesfully. I just downloaded the 64 bit Qt version and will try it, hope it will be fine with MD and MDd settings.
Thank you VERY MUCH! Your directions seemed to work. I did have to make a bunch of changes, but finally figured it out. The changes were in the PATHs. Now I need to go through the resulting compiler code and see if it all got loaded and is going to work properly.
