Assistance on building Qt SDK from source for Ubuntu 22.04 on aarch64
-
Hello,
We are using Jetson Orin Nano companion computer in our application development for robotics application. The Jetson Orin Nano comes with QLibc
jetson@ubuntu:~/Downloads$ ldd --version
ldd (Ubuntu GLIBC 2.35-0ubuntu3.11) 2.35

Written by Roland McGrath and Ulrich Drepper.During the Qt installation, I run into version mismatch.
/home/jetson/Qt/6.10.1/gcc_arm64/libexec/qmlimportscanner: /lib/aarch64-linux-gnu/libm.so.6: version GLIBC_2.38’ not found (required by /home/jetson/Qt/6.10.1/gcc_arm64/libexec/../lib/libQt6Qml.so.6)

Therefore I believe I have to rebuild Qt for 22.04 on aarch64 from the source.
I came across this wiki post to build Qt from source on Ubuntu 22.04.
https://wiki.qt.io/Building_Qt_Creator_from_Git_on_Ubuntu_22.04
I want to confirm from you all if these are still the correct steps to proceed on my environment.
Thanks for your help,

Hi and welcome to devnet,
I would say no since you want to build Qt but these are instructions for Qt Creator.
You are likely looking for this page: https://wiki.qt.io/Building_Qt_6_from_Git -
Thank you @SGaist I will follow the instructions. While I was validating the versions, I have the following C++ on my environment. The wiki is mentioning C++17.

On this step
../configure -prefix /home/jetson/Qt
I am seeing the following error.
-- Configuring submodule 'qttools'
CMake Error at /usr/lib/llvm-14/lib/cmake/clang/ClangTargets.cmake:750 (message):
The imported target "clangBasic" references the file"/usr/lib/llvm-14/lib/libclangBasic.a"but this file does not exist. Possible reasons include:
-
The file was deleted, renamed, or moved to another location.
-
An install or uninstall procedure did not complete successfully.
-
The installation package was faulty and contained

I Installed the missing development package: the necessary package is libclang-dev or the version-specific libclang-14-dev. Making progress ...

I run into the following error and build. I did some search in Google but I wasn't able to determine the exact cause of this error.

You should use only one thread to see exactly what is going wrong.
That said, it looks like it happens in the QtWebEngine module. Unless you actually need it, I would recommend leaving it out. It's a massive module that is usually hard to build.
