3D Install Qt6

SGaist

I haven't read the content of these instructions so I currently do not know their scope.

Can you point me to them ?

ofmrew

export /home/bob/Qt/Tools/bin:/home/bob/Qt/tools/Conan:/home/bob/Qt/Tools/Ninja:$PATH
bash: export: `/home/bob/Qt/Tools/bin:/home/bob/Qt/tools/Conan:/home/bob/Qt/Tools/Ninja:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin': not a valid identifier

They are in Qt Forum at: Qt6 Add-on src package build using Conan package manager

@ofmrew said in 3D Install Qt6:

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

My mistake I forgot to assign to PATH:

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

That worked.

ofmrew

@ofmrew Trying to install 3D I used and got:

bob@bob-linux:~$ export PATH=/home/bob/Qt/Tools/bin:/home/bob/Qt/tools/Conan:/home/bob/Qt/Tools/Ninja:$PATH
bob@bob-linux:~$ cd /home/bob/Qt/Conan3D
bob@bob-linux:~/Qt/Conan3D$ conan install qt3d/6.0.0@qt/final --build=missing --profile=G:/Tools/Conan/profiles/'''qt-6.0.0-gcc-x86_64''' -s build_type=Release -g cmake_paths -g=cmake -g deploy

Command 'conan' not found, did you mean:

command 'conman' from deb conman (0.2.7-1build2)

Try: sudo apt install <deb name>

It looks like the environment variables were not set. Should I just modify the code to show the paths?

SGaist

Where is the Conan executable locate ?

ofmrew

@ofmrew It is located in /home/bob/Qt/Tools/Conan which is one of the paths prepended to PATH.

SGaist

You have a typo in your export, it's Tools not tools.

ofmrew

@SGaist Thanks. My eyes are not what they used to be.

I made the change but it failed because the profiles should reference qt-6.0.1-gcc-x86_64. But when I make that change I get:

bob@bob-linux:~$ export PATH=/home/bob/Qt/Tools/bin:/home/bob/Qt/Tools/Conan:/home/bob/Qt/Tools/Ninja:$PATH
bob@bob-linux:~$ cd /home/bob/Qt/Conan3D
bob@bob-linux:~/Qt/Conan3D$ conan install qt3d/6.0.0@qt/final --build=missing --profile=G:/Tools/Conan/profiles/'''qt-6.0.1-gcc-x86_64''' -s build_type=Release -g cmake_paths -g=cmake -g deploy
ERROR: Profile not found: G:/Tools/Conan/profiles/qt-6.0.1-gcc-x86_64
bob@bob-linux:~/Qt/Conan3D$

This is a copy of the file name: qt-6.0.1-gcc-x86_64. Am I going blind?

SGaist

Something I find strange is that there are three quotes around the profile name.

ofmrew

@SGaist I copied this from the instructions: --profile=G:/Tools/Conan/profiles/'''qt-6.0.1-gcc-x86_64'''

One more question. If I am going to use QtCreator for the 3D programming should I use -g=qmake?

SGaist

I would try without all the quotes.

No, Qt Creator can handle both cmake and qmake project.
And I think it's unrelated in this context, Qt 6 used cmake as build system.

ofmrew

@SGaist Still cannot find it:

conan install qt3d/6.0.0@qt/final --build=missing --profile=G:/Tools/Conan/profiles/qt-6.0.1-gcc-x86_64 -s build_type=Release -g cmake_paths -g=cmake -g deploy
ERROR: Profile not found: G:/Tools/Conan/profiles/qt-6.0.1-gcc-x86_64

SGaist

Wait... why are you using a Windows style path while building on Linux ?

ofmrew

@SGaist Switching between Linux and Win 10 has its hazards. Made the change and got deep into it all the way to:

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):

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:
