3D Install Qt6
-
@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.

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?

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.

No, it does not.

@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:

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:
export PATH=/home/bob/Qt/Tools/bin:/home/bob/Qt/Tools/Conan:/home/bob/Qt/Tools/Ninja:$PATH
cd /home/bob/Qt/Conan3D
conan install qt3d/6.0.1@qt/final --build=missing --profile=/home/bob/Qt/Tools/Conan/profiles/'''qt-6.0.1-gcc-x86_64''' -s build_type=Release -g=qmake -g qmake_paths -g cmake_paths -g=cmake -g deployWhat is my next move?
-
No include missing from that file ?

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

@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 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.
