I need to compile QGC on Ubuntu with arm architecture. I installed Ubuntu20.04.02 ARM64 with parallel desktop17 on a MacBook pro with m1 pro CPU, and cloned the QGC repository . For the latest version of QGC, I need to install Qt5.15.2. But I'm a new person on Qt and I don't know how to install Qt5.15.2 on my machine. So I switched to an older version of QGC to compile, which only required Qt5.11+. So there is this topic. I hope to get your help. The ultimate goal is to install a specific version of Qt on my machine. I find it difficult to install Qt on a machine with arm architecture. Do you have any suggestions?

[jsulm]

@mchmch Sorry, I do not know how to get these private modules from Ubuntu.
You get them if you install Qt using official Qt Online Installer.

[mchmch]

I try to build Qt5.15.2 by source code, but everything is OK until “sudo make install"

collect2: error: ld returned 1 exit status

@mchmch Why do you want to build Qt by yourself instead of downloading the online installer and installing the version you need?

[mchmch]

@jsulm online installer ? it didn't work, I don't know why.

now I can build the qt5 on my computer, but I don't know how to use it if I don't install it. Building_Qt_5_from_Git

@mchmch said in Project ERROR: Unknown module(s) in QT::

it didn't work, I don't know why

What happened?
Building Qt isn't trivial. You should really try to install using the online or offline installer.

"now I can build the qt5 on my computer" - like described in the link you posted. What exactly is the problem?

[mchmch]

@jsulm I can't open the .run file, I am sure that everything is under the guiden. I think the problem is that the cpu architecture is different.

[jsulm]

This post is deleted!

[jsulm]

@mchmch OK, I see now that you're on ARM.
In this case you have to build Qt by yourself.
Then please provide more information: which step from the build explanation does not work?

[mchmch]

@jsulm now I get the way to Set the Environment Variables, by Qt for Linux/X11 - Building from Source after by the wiki. The wiki didn't tell me how to add the PATH.

PATH=/usr/local/Qt-%VERSION%/bin:$PATH
export PATH

[mchmch]

@mchmch but now the problem again, and seem to different:

Then please provide more information: which step from the build expla

summary：
step 1. I follow the wiki :

sudo apt-get build-dep qt5-default
sudo apt-get install libxcb-xinerama0-dev

sudo apt-get install build-essential perl python git

sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev

sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby

sudo apt-get install libasound2-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-good1.0-dev libgstreamer-plugins-bad1.0-dev


git clone https://code.qt.io/qt/qt5.git
cd qt5
git checkout 5.15.2

perl init-repository

git submodule update --init --recursive                     

./configure

make -j8

sudo make install -j8

PATH=/usr/local/Qt-%VERSION%/bin:$PATH
export PATH

and now I can see that :

Hi,

How is searching for QtMultimedia related to the location module missing ?

[mchmch]

@SGaist didn't work

[SGaist]

What did not work ?
