3D Install Qt6

[ofmrew]

@SGaist What about Msys does that need to be installed?

[SGaist]

No, it does not.

[ofmrew]

@SGaist I find that I have multiple mingw and msys installed, some dating back 6 years. I believe tha I need to clean my computer and start with a fresh installation.

[ofmrew]

@ofmrew Back to Mint Linux. I found an Internet post on how to test the Vulkan installataion: https://linuxconfig.org/install-and-test-vulkan-on-linux. I installed Steam and DoTA 2. It seemed to run without a problem. So now I am really confused about the conan message: /home/bob/.conan/data/qt3d/6.0.1/qt/final/build/9105b5b4ab5d474532cfc28699da368141e8a4cf/src/render/surfaces/vulkaninstance.cpp: In lambda function:

54 | QVulkanInstance* v = new QVulkanInstance;

It occurred at: [ 48%] Building CXX object src/render/CMakeFiles/3DRender.dir/surfaces/vulkaninstance.cpp.o

The final part of the log:

If the Vulkan game DoTA runs, which implies that Vulkan is correctly installed, then (1) is it a bug or is there an error in my statement:

What is my next move?

[SGaist]

No include missing from that file ?

[ofmrew]

@SGaist That does not answer my question: If the include file is missing is it my fault or a bug? Your reply of No gives me no hint as what I should do. What should I do?

[SGaist]

I meant is there any include statement missing from that file ? It should not but who knows.

[ofmrew]

@SGaist I looked but I could not see any problem. I was about to run a validation on the installation of Valkan, but then I used the maintenance tool to get the latest. There seems to be that some files are out of synch, for example qt3d/6.0.1@qt/final is required but then --profile=/home/bob/Qt/Tools/Conan/profiles/'''qt-6.0.2-gcc-x86_64''' is required. Now I get:

conan install qt3d/6.0.1@qt/final --build=missing --profile=/home/bob/Qt/Tools/Conan/profiles/'''qt-6.0.2-gcc-x86_64''' -s build_type=Release -g cmake_paths -g=cmake -g deploy
Configuration:
[settings]
arch=x86_64
build_type=Release
compiler=gcc
compiler.libcxx=libstdc++11
compiler.version=7.5
os=Linux
[options]
qt6=6.0.2
[build_requires]
[env]
QT_PATH=/home/bob/Qt/6.0.2/gcc_64
qt3d/6.0.1@qt/final is locked by another concurrent conan process, wait...
If not the case, quit, and do 'conan remove --locks', which does nothing!

MY question is: has anyone actually downloaded qt63d and got it to work, for me neither win 10 nor mint linux has been successful.

Maybe someone should look at this!

[ofmrew]

@ofmrew It looks like the Vilkan SDK is bad, vkvia will not work; however, both vkcube and vulkaninfo work. Looks like it is my problem!

[ofmrew]

@ofmrew I think I found the problem:
Vulkan Configurator
Vulkan Development Status:

• Layers override: "Validation" configuration
• $VULKAN_SDK environment variable not set
• Could not find a Vulkan Loader.
  However, this is where my lack of Linux skills is killing me: I am not sure how to permanently set the environment variables. I have easily set then in Windows 10, but my use of vi was last in 1990 and even then my skills were only marginal. I would appreciate some help.

[SGaist]

You can edit the .profile file in your home directory.

Some more information here.

[ofmrew]

@SGaist Thanks very much, that is more readable than the information that I found on the internet.

[ofmrew]

@ofmrew New problem:
qt3d/6.0.1@qt/final is locked by another concurrent conan process, wait...
If not the case, quit, and do 'conan remove --locks'

quit
conan remove --locks

What is this and how do I get past it?

[SGaist]

I wonder if related to this Conan bug ?

Maybe clearing the cache might help.

[ofmrew]

Back to win 10 3D install. For anyone that might wonder how to execute conan on win 10: click the start button, then type cmd and you should see an option like Qt 6.02 (MinGW 8.1.0 64-bit) select it and you will have the correct Command Prompt.

I got past finding Vulkan, but then:

Look like I am missing OpenSSL and Perl. Do I need to install those or should they have been installed? Making some progress!

[SGaist]

Neither is installed as Perl is needed when building from git and OpenSSL has export restrictions is some countries so the software creator shall handle it. You can grab OpenSSL through Qt's maintenance tool.

[ofmrew]

@SGaist Thanks again. From now on if something is not found the first place I will look is the Maintenance Tool. WRT the Linux Conan install of 3D, I am heading into the unknown. The .bashrc file is read only so I will use su to become superuser and xed to edit the file to add the Vulkan environment variables, the we will see how the install goes. Problem:
bob@bob-linux:~$ su
Password:
su: Authentication failure
So now it is on to learning about sudo.

[ofmrew]

@ofmrew That worked, but I think I make a mistake: I included -g cmake_paths -g=cmake -g qmake_paths -g=qmake, hoping to get both CMake and QMake files; however, it looks like qmake_paths is not a valid option. When I look at the build directory, Conan3D, it show the following files: conan_paths.cmake, conanbuildinfo.cmake, conanbuildinfo.pri, conanbuildinfo.txt and deploy_manifest.txt and the directory qr3d.

The final error was:
qt3d/6.0.2@qt/final: Created package revision 90168ed2bee78e6cfe3c11647c572f1f

My question is: Is was is there usable or mus I start over? We now know the qmake_paths is not valid but qmake is valid.

Any advise?

[ofmrew]

@ofmrew Linux is giving me problem. First, conan install qt3d/6.0.2@qt/final cannot be found and when I try conan install qt3d/6.0.1@qt/final I get conan locked. I clean the cache but it does not work. This bug has been around since June of 2020.
Is there a work around? Would Qt 6.0.3 help?

[SGaist]

Does dropping qmake_paths work ?
