3D Install Qt6

ofmrew

@SGaist Switching between Linux and Win 10 has its hazards. Made the change and got deep into it all the way to:
CMake Generate step failed. Build files cannot be regenerated correctly.

What did I screw up this time?

ofmrew

@ofmrew I got a number of CMake Errors before the line: CMake Generate step failed. Build files cannot be regenerated correctly. I did not include them because there is a limit on the size of a post, been down that road already today. An example is:

CMake Error at /home/bob/Qt/6.0.1/gcc_64/lib/cmake/Qt6/QtModuleHelpers.cmake:48 (add_library):
Target "3DExtras" links to target "XKB::XKB" but the target was not found.
Perhaps a find_package() call is missing for an IMPORTED target, or an
ALIAS target is missing?
Call Stack (most recent call first):
src/extras/CMakeLists.txt:7 (qt_internal_add_module)

Any suggestions?

SGaist

Missing libxkbcommon related development package ?

ofmrew

@SGaist said in 3D Install Qt6:

libxkbcommon

What is that and were do I find it?

SGaist

It's one dependency of the xcb plugin and your distribution package manager should provide it.

ofmrew

@SGaist It is not included in the Mint Software Manager.

ofmrew

@ofmrew Installed it. Now I get:

SGaist

Well, Mint seems to have it.

ofmrew

@SGaist Not really I had to find it on the Web.

SGaist

You are missing the zlib development package.

ofmrew

Looks like ZLIB is missing, what is that?

ofmrew

@ofmrew I should have waited, I found zlib1g-dev, is that what I need to install?

ofmrew

@ofmrew Again, I also found zlib 1.2.11, but no way to install.

ofmrew · @ofmrew Again, I also found zlib 1.2.11, but no way to install.

@ofmrew I installed zlib1g-dev and it might be working!

ofmrew

@ofmrew I spoke too soon.

SGaist

Looks like Vulkan is not as optional as stated in your logs above.

From memory, you need that SDK.

ofmrew

@SGaist Thanks for all your help so far, but exactly what do I need because I have looked and I have yet to find an installer for the Vulkan SDK and QVulkanInstance. I am at a loss. You should know because Qt is part of the Khronos group. Please help, we are so close to having 3D installed.

One other question: can I have both -g=cmake and -g qmake and it I have the latter do I need a -g qmake_paths?

SGaist

The page I linked provides a link to the SDK download page.

@ofmrew said in 3D Install Qt6:

You should know because Qt is part of the Khronos group..

I think there's a mistake here. I do not work for the Qt Company.

ofmrew

@SGaist Sorry about that, bad assumption on my part. It makes the help even more outstanding. Can you answer the question: can I have both -g=cmake and -g qmake and it I have the latter do I need a -g qmake_paths?

Also, do you know of a good reference on installing Valkan, I downloaded the sdk from the URL you provided, but I am stuck on how to proceed. Thanks.

Which distribution are you using ? For Ubuntu based there are easy to follow instructions.
