3D Install Qt6

ofmrew · wrote on 6 Mar 2021, 19:04

In the instructions for conan it states that the three entries must be prepended to the $PATH environment variable. With Win 10 I have not choice but to permanently add the entries; however, with Mint Linux I am not sure. I assume the I will use /home/bob/Qt/Tools/Cmake/bin:/home/bob/Qt/Tools/Conan:/home/bob/Qt/Ninja:$PATH, but leaves me with two question: 1. What linux command do I use, export? 2. Will the environment variables be permanently set? Thanks in advance for the indulgence, I learned Unix over 30 years ago and have forgotten it.

Hi,

export is the right command for the terminal.

If you want to make it permanent, you should modify your .bashrc, .bash_profile or corresponding shell configuration file.

ofmrew · 6 Mar 2021, 20:41

@SGaist One question still remains: will those changes be required later?

SGaist · wrote on 6 Mar 2021, 19:45

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

Can you point me to them ?

ofmrew · 7 Mar 2021, 16:37

@ofmrew I tried:

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 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 · wrote on 7 Mar 2021, 18:42

Where is the Conan executable locate ?

ofmrew · O ofmrew 7 Mar 2021, 16:57

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

SGaist · 7 Mar 2021, 19:16

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

ofmrew · S SGaist 7 Mar 2021, 18:54

@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 · 7 Mar 2021, 19:22

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

ofmrew · S SGaist 7 Mar 2021, 19:18

@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 · 7 Mar 2021, 19:30

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 · S SGaist 7 Mar 2021, 19:24

@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 · 7 Mar 2021, 19:43

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

ofmrew · 7 Mar 2021, 19:56

@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 · O ofmrew 7 Mar 2021, 19:43

@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 · 7 Mar 2021, 20:03

Missing libxkbcommon related development package ?

ofmrew · S SGaist 7 Mar 2021, 19:59

@SGaist said in 3D Install Qt6:

libxkbcommon

What is that and were do I find it?
