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
CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

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:

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:
export PATH=/home/bob/Qt/Tools/bin:/home/bob/Qt/Tools/Conan:/home/bob/Qt/Tools/Ninja:$PATH

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 deploy

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

[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!
