3D Install Qt6

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?

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

@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:

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?
