3D Install Qt6
-
The page I linked provides a link to the SDK download page.

You should know because Qt is part of the Khronos group..
I think there's a mistake here. I do not work for the Qt Company.
@SGaist Sorry about that, bad assumption on my part. It makes the help even more outstanding. Can you answer the question: can I have both -g=cmake and -g qmake and it I have the latter do I need a -g qmake_paths?
Also, do you know of a good reference on installing Valkan, I downloaded the sdk from the URL you provided, but I am stuck on how to proceed. Thanks.

Sorry, that one I currently do not know.

Which distribution are you using ? For Ubuntu based there are easy to follow instructions.

Ubuntu
I got these and executed them:
Ubuntu
AMD It's best to enable a PPA for the latest Mesa drivers. There is a PPA that packages and releases the latest changes straight from Mesa's Git. Add the PPA to your system and update. Then, upgrade your system. It will automatically upgrade your existing Mesa packages.$ sudo add-apt-repository ppa:oibaf/graphics-drivers
$ sudo apt update
$ sudo apt upgrade
When it's done, install the Vulkan packages.apt install libvulkan1 mesa-vulkan-drivers vulkan-utils
NVIDIA Ubuntu also has a great repository for the NVIDIA proprietary drivers. Add it to your system, and update Apt.
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt upgrade
Now, install your drivers and Vulkan.
$ sudo apt install nvidia-graphics-drivers-396 nvidia-settings vulkan vulkan-utilsBut the conan install failed:

-
Looks like there's a missing include in the cpp file that triggers the error.
-
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 deploycmd /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.
-
What if you use backslashes for the path to the profile ?
-
@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. -
IIRC, you have the option to get it from the MaintenanceTool.

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 ?
-
@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.
@ofmrew I got CMake installed, but now I get:

AFAIK, it should target Ninja.

@ofmrew Another question, does the message:

indicate a problem with the CMake installation and if so how can I check it? -
Did you open a command prompt pre-configured for MinGW ?
-
@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.
