3D Install Qt6

SGaist

Looks like there's a missing include in the cpp file that triggers the error.

@SGaist That looks like one of the downloaded files: /home/bob/Qt/6.0.1/gcc_64/include/QtGui, but I am not sure if it is my problem or a bug? Any ideas?

ofmrew

Since the Linux 3D install is at a deadend, I am trying Win 10 but with no success. I am trying:

cd c:\Qt\Conan3D
conan.exe install qt3d/6.0.1@qt/final --build=missing --profile=C:/Qt/Tools/Conan/profiles/'''qt-6.0.2-mingw81_64''' -s build_type=Release -g cmake_paths -g=cmake -g qmake_paths -g=qmake -g deploy

cmd /k

I checked that the files and directories are correct and the only thing I sees that could cause a problem is "/" versus ""; howevr, I tried it both ways but still got the erro that the Profile was not found.

SGaist

What if you use backslashes for the path to the profile ?

ofmrew

@SGaist It was that and the three quotes. The following worked:

cd c:\Qt\Conan3D
conan.exe install qt3d/6.0.1@qt/final --build=missing --profile=C:\Qt\Tools\Conan\profiles\qt-6.0.2-mingw81_64 -s build_type=Release -g cmake_paths -g=cmake -g qmake_paths -g=qmake -g deploy
cmd /k
But I got this error:
CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
CMake 3.15.0 or higher is required. You are running version 3.10.1
How do I get a version of cmake that will work with conan on Win 10.

SGaist

IIRC, you have the option to get it from the MaintenanceTool.

ofmrew

@ofmrew I looked at Qt\Tools and there is a CMake_64. Should this have been used?

ofmrew

@SGaist I do not see CMake as something that can be installed, unless I am looking in the wrong place. Any help would be appreciated.

SGaist

There's a separate entry in the Maintenance Tool to select Conan as well. You should found it there.

How did you install the current version you have ?

ofmrew

@ofmrew I got CMake installed, but now I get:

Any Ideas?

SGaist

AFAIK, it should target Ninja.

ofmrew

@SGaist I am not sure I understand. What should tartget Ninja.

And what about the message:
qt3d/6.0.1@qt/final: WARN: Package binary is corrupted, removing: 0f29c7292f66ab3b189fa2809bdfcf230d253f0f

I checked and the path to ninja is in PATH.

What do I need to do?

ofmrew

@ofmrew Another question, does the message:
CMAKE_PREFIX_PATH for 'qt3d/6.0.1' build is: C:\Qt\6.0.2/mingw81_64

indicate a problem with the CMake installation and if so how can I check it?

SGaist

Did you open a command prompt pre-configured for MinGW ?

ofmrew

@SGaist I have heard that, but I well look it up.

ofmrew

@ofmrew I have two questions:

In the post "Qt3D 6.0.2 on Windows using MinGW 8.1.0" I note that all of the files use "/". So am I to assume that conan will make the conversion?
In that same post it was stated "More specifically I opened the appropriate Qt MinGW 8.1.0 command prompt" and executed "conan.exe . . .". Is it absolutely necessary to do that step and if so why is it not noted?

I hope that the documentation writers will look at all of the post being made about the troubles we are having with conan.

ofmrew

@ofmrew I am trying setup Command Prompt for

ofmrew

@ofmrew Sorry but the previous post was sent prematurly. It shoyuuld have said the I was setting Command Prompt for ming81_64 by adding c:\Qt\6.0.2\ming81_64 to PATH, but g++ --version is not recognized. What am I doing wrong?

SGaist

IIRC, Qt provides a set of shortcut for command prompts preconfigured for use. You should use these.

As for your PATH changes, did you check where exactly g++ is located ?

ofmrew

@SGaist I am learning more than I never wanted to know about Linux and Win 10. Back in 1990 when I was at the announcement of Win NT I would have loved this stuff, but now I just want to program 3D graphics.

I searched for g++ and did not find it, but I did find a number of g++ prefixed by a compiler.
Does the Installer actually install mingw or just a module, i.e., do I need to install mingw64 on my computer. One post in stackoverflow "https://stackoverflow.com/questions/22873884/how-do-i-run-configure-with-mingw" states that both mingw and msys must be installed. I that correct? If so, then do I follow the steps that post suggest?
