Unsolved QtCreator doesn't open the CMake Wizard

[by-erik]

Hi,

i'm trying to use QtCreator 4.1.0 to open an existing cmake project. When i open a CMakeLists.txt via File -> "Open File or Project..." the CMake Wizard doesn't appear. Instead of the CMake Wizard i get into "Configure Project" asking me to select a kit.

The CMakeLists.txt is correct and works fine when using cmake directly.

When i start qtcreator over a terminal i get the following message:
"The command "/qmake" could not be started."

Maybe this is the cause of the problem.

qmake is already installed

# find /usr -name qmake -type f
/usr/lib/x86_64-linux-gnu/qt5/bin/qmake

and executable

# ls -lsa /usr/lib/x86_64-linux-gnu/qt5/bin/qmake
3004 -rwxr-xr-x 1 root root 3075784 Mai 19  2015 /usr/lib/x86_64-linux-gnu/qt5/bin/qmake

Maybe some can help me with this issue.

Erik

@by-erik qmake is not needed for CMake projects.
What happens if you just continue with selecting a Kit?
As far as I know CMake handling changed in QtCreator recently.

Thanks for your reply.

For a simple HelloWorld cmake project continue with selecting a Kit works fine. But a more complex cmake project ended up in a configuration loop.

You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_CXX_COMPILER= /usr/bin/g++

In the meantime i found out a workaround.

I did install QtCreator 3.2.1 and open initially the project with this version. QtCreator 4.1.0 converts the CMakeLists.txt.user file and works fine now.

Just another workaround.

• Tools -> Options...
  • Build & Run -> Kits
    • Select Desktop (default) and press Clone
    • In the cloned one Change 'CMake Configuration' and remove 'CMAKE_CXX_COMPILER:STRING=%{Compiler:Executable}'

Just for the record. My cmake project makes use of

SET(CMAKE_CXX_COMPILER /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++)

It seems that 'CMAKE_CXX_COMPILER:STRING=%{Compiler:Executable}' overwrites CMAKE_CXX_COMPILER from the CMakeLists.txt file.
