I’ve been having the worst possible trouble trying to get Qt to compile a very simple beginner program, and now it’s starting to drive me insane.
I’m very new to programming, so please bare with me. The whole lib’s and dll’s are still quite a engima to me, I thought libs were separate statically linked libraries but apparently you can statically link a .dll file using it’s associated .lib (:S). Plus Qmake and it’s cross-platform build ability and quite how it functions, console commands is also an area of confusion. If anyone would care to explain that would be nice.
Anyway regardless my real issue is I’ve been trying to compile an OpenGL application. Following the initial two attempts there was an issue with finding QApplication.h. This was resolved by following some advice to clean the build folder and simply run QMake. This worked but the build was followed by errors with the inability to open the “OpenGL.exe”. I figured this has something to do with me constantly deleting the build folder. I didn’t know how to remedy those errors so I just played around with the .pro (not really understanding what I was doing).
Furthermore after much more bewildering errors, the whole QtCreator decided to crap up on me. After attempting to run it in administrator and restarting it there’s now a warning symbol in the QtCreator -> Tools -> Build & Run -> Kits. This symbol suggests the Microsoft Visual 2010 compiler cannot produce code for this Qt Version. Even though it was perfectly happy to compile earlier and detected Visual Studio 2010 express (I followed the steps including Windows 7.1 SDK and SP1 to ensure it was fine).
Additionally there is an error suggesting “Mkspec not found in Qt Version” even while there is a folder inside mkspecs (“win32-msvc2010”) containing a qmake.conf. So everything appears in order but I’m unable to select a Qt Version under kits, it’s a blank box, attempting to click manage leads me to the “Qt Version” tab, where I’m greeted by another error suggesting:
“Could not determine the path to the binaries of the Qt installation, maybe the qmake path is wrong?”
However on further inspection the path is exactly right and attempts to add manually lead to the exact some folder where “qmake.exe” is rightfully located.
I’m pulling my bloody hair out, I have seriously no clue about 99% of what I’m doing and this isn’t helping. Other people on-line with similar errors are generally Linux users (which I have no experience with so I can’t transpose their resolution).
Others are suggesting using “Command Prompt” while I can follow what they’re doing step-by-step such as typing “qmake -set QT_VERSION “5.0.1”“ I have no idea if this is working or valid. Still cmd.exe function and how it works is also an engima and it doesn’t help when some people suggest just set PATH+= ? Are these people referring to typing this into the .pro file. This does absolutely nothing because even after doing so I can’t compile the code because the immediate error is invalid QtVersion, attempts to get a fresh .pro file are also impossible because now making new projects asserts no kits are available.
God I’m going crazy please help me understand this stuff and fix the problem. I’d be extremely grateful.
