3D Install Qt6

SGaist

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

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

@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 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 ?

@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?

SGaist

You do not need to install MinGW independently. The online installer as well as the Maintenance Tool gives you the option to install the version used for the pre-built binaries.

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 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:

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.

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