Miguel Gimenez:
Post a full rebuild log, see this link

AndrewCot:
LeslieS, Can you please also upload the project CBP file as well as the log.

Note that the compiler options mentioned in the faq are not found in the compiler settings (at least not in that I could find). In fact I couldn't find those options anywhere.

--- Code: ---Code::Blocks version, compiler log (go to Settings->Compiler and debugger...->Build options (tab) and check Save build log and Always output the full command line),
--- End code ---

Miguel Gimenez:
Remove this paths from the compiler search directories and global compiler search directories from all targets:

--- Code: ---/usr/lib/x86_64-linux-gnu/qt5
/usr/lib/qt5
/usr/share/qt5

--- End code ---
and add only this (and only to the project build options):

--- Code: ---/usr/include/x86_64-linux-gnu/qt5

--- End code ---

LeslieS:
If I did it correctly it seems to be the same result.
Using the menu options to change the settings didn't actually change the cbp file.
I had to go in and manually remove the items from it using a text editor I am not 100% sure I got it right.

I also tried to start a new project but have run into some strangeness there too. It is endlessly looping "It seems that this project has not been built yet. Do you want to build it now?". Selecting yes just brings this up again.
Selecting no brings up a window "sh: 1: /home/noone/bin/debug/test2: file not found".

I think that maybe CodeBlocks is geared towards people who are already quite familiar with the intricacies of C/C++ compiling.
It could be that there is too much I don't know.
