How to install QCA for Qt Creator 5 on a Win7 32bit system
-
You should be able to get the information from the Maintenance tool
-
Ok, I found Qt ver. 1.0.8 with Qt 5.4 ver. 5.4.0-1 and Qt 5.3 ver. 5.3.2
-
MSVC ? MinGW ?
-
Oh sorry I missed to open that stuff :/
- Qt 5.4 MinGW 4.9.1 (32 bit) OpenGL ver. 5.4.0-1, Qt WebEngine ver. 5.4.0-1
- Qt 5.3 MinGW 4.8.2 (32 bit) ver. 5.3.2-0
- Tools: MinGW 4.8.2 ver. 4.8.2, MinGW 4.9.1 ver. 4.9.1-2
- Qt Extras Qt Canvas and QtWebView (doesn't matter at this point I guess)
No MSVC selected.
-
No problem, then when calling cmake you should set the generator to "MinGW Makefiles"
-
Ok. make -G "MinGW Makefiles" c:\qca_2-1-0\ says
CMake Error: Error: generator : MinGW Makefiles
Does not match the generator used previously: NMake Makefiles Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.Should I remove the suggested file?
-
Yes, you can empty the folder you used
-
But this is the cmake folder c:\cmake.
Do I only have to delete that file or can i specify a folder and how? -
Don't call cmake from there.
Call it either in a build folder inside QCA's sources or at the same level as the sources
-
Ok I copied cmake into the qca folder and it said
C:\qca_2-1-0>cmake -G "MinGW Makefiles" c:\qca_2-1-0\
C:\qca_2-1-0>cmake -G "MinGW Makefiles" c:\qca_2-1-0
CMake Error: Could not create named generator "MinGW CMake Error: The current CMakeCache.txt directory C:/qca_2-1-0/CMakeCache.txt is different than the directory c:/cmake/bin where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure,
reedit the CMakeCache.txtThen I copied QCA into a folder inside of the cmake folder and it says
C:\cmake\bin>cmake -G "MinGW MakeFiles" c:\cmake\bin\qca
CMake Error: Could not create named generator MinGW MakeFiles -
Don't fiddle with these folders like that
@
cd C:\qca_2-1-0
mkdir build
cd build
C:\cmake\bin\cmake .. -G "MinGW Makefiles"
@And it should start setting things up.
-
I still get the error
CMake Error: Could not create named generator MinGW MakeFiles -
You are writing "Makefiles" wrong the f is not uppercased
-
Oh sorry :/
Now I get a new error. Inside the build folder there is a new file called CMakeCache.txt and a new folder called CMakeFiles in wich is also a new file called cmake.check_cache.C:\qca_2-1-0\build>c:\cmake\bin\cmake .. -G "MinGW Makefiles"
CMake Error: CMake was unable to find a build program corresponding to "MinGW Ma
kefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a differe
nt build tool.

-
Are you using a self installed MinGW or the one provided with Qt ?
-
I'm not sure but I think I installed MinGW before or after Qt by myself for some reasons. In the Tools folder of Qt are the MinGW versions I mentioned before. So I installed it at least 2 times I guess.
Edit: I think c:\MinGW\ is the rest of an old installation. Because the folder has way less files than c:\Qt\Tools\mingw491_32\ or c:\Qt\Tools\mingw482_32\
-
Then just remove it completely (however I don't remember if there's an entry for it in Windows Control Panel)
IIRC, you should also have shortcut in Start Menu -> Qt that starts a command line with MinGW setup, use that one and you should be good to go.
-
I can't find any hints how to uninstall it (if even possible) so I just renamed c:\MinGW to c:\MinGW_OLD just in case I need it for something I forgot.
In Start Menu -> Qt are only these entries
- Qt Creator (Community)
- Qt Maintenance Tool
- qt-project.org
- README
- Unistall Qt
-
Ok then, take a look in your Qt folder and search for a file called qtenv2.bat
Once you have found it you can create a shortcut containing:
@C:\Windows\System32\cmd.exe /A /Q /K C:\Qt\Qt5.4.1\5.4.1\mingw49_32\bin\qtenv2.bat@
Adapt the path to yours
Then start the command line using that shortcut and you should have mingw at your disposition
-
Ok, I did so. Thank you! When I run C:\qca_2-1-0\build>c:\cmake\bin\cmake .. -G "MinGW Makefiles" now, I'm getting the same error again.
C:\qca_2-1-0\build>c:\cmake\bin\cmake .. -G "MinGW Makefiles"
