How to install QCA for Qt Creator 5 on a Win7 32bit system
-
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"

Did you start from a clean folder ?
-
I tried again from a clean folder and running the shortcut as admin before.
Somehow it worked. :)
Now I have some folders and files in c:\qca_2-1-0\build
Thank you very much!
How to move on from here? -
Admin ? Strange…
"Here":https://github.com/JPNaude/dev_notes/wiki/Using-the-Qt-Cryptographic-Architecture-with-Qt5 you have a nice explanation on how to check that everything is fine
-
So now I have to run make from inside the build folder?
-
run make ?
Can you be more specific ? -
Sorry that I didn't reply. I couldn't use the computer for a while.
Well I don't know where to start at the given link.

You can run the qcatool.exe to check that everything is in place
