Need help statically building qt for Ubuntu

SGaist

Hi and welcome to devnet,

QtWebEngine cannot be built statically because the chromium project that powers it does not allow that.

That said, you should only build the modules you need rather than the full of Qt.

QtWebEngine

Thanks this might sound dumb but I have -skip qtwebengine above . How do I remove the modules I do not need?

SGaist

I missed it. The most simple is to remove the folder from the source tree. Either move it out or delete it.

Thanks for your help. I ended up reverting to 5.17 and it looks like the QT components are statically linked but I'm now having Multiple issues with other components (i.e libcurl)

Sorry for my ignorance but what do I need to do for the non qt components. In my project file I thought adding this would be enough for my project.

unix:!android: LIBS += -lcurl

But on my teammate machine he needed to install the following on his distribution to work
sudo apt-get -y install libpcre2-16-0
sudo apt-get -y install libxcb-xinput0
sudo apt-get -y install libcurl4-openssl-dev
sudo apt-get -y install libxkbcommon-dev
sudo apt-get -y install libx11-xcb-dev
sudo apt-get -y install libxcb*-dev
sudo apt-get -y install libfontconfig1-dev
sudo apt-get -y install libxkbcommon-x11-dev
sudo apt-get -y install libgtk-3-dev
sudo apt-get install --reinstall libxcb-xinerama0

The second issue may not have anything to do with static linking but whether how he is trying to launch our application. I'll either post a new topic on that issue.

Do you mean that those components are dynamically linked? If so and you want to link them statically you need all those components also built as static libs.

hamer

If you want to use Qt 6 then you have to manually add the following to qtwebengine/configure.cmake:

if(QT_CONFIGURE_RUNNING)

    function(check_for_ulimit)
    endfunction()

At least, this fixed the problem for me.

mijutu

@hamer There is check_for_ulimit function in qtwebengine/cmake/Functions.cmake but cmake 3.25 doesn't seem to notice it. Downgrading to cmake 3.24.3 helps.

@hamer Thank you for sharing

Hi
I tried to manually edit the configure file but I failed. I got the error
./configure: 31: Syntax error: word unexpected (expecting ")")
I quite dont posses expertise regarding programming and I dont Know how to edit it, any help please.
what line should be edit and how

srcpath=dirname $0
srcpath=(cd "$srcpath"; pwd)
configure=$srcpath/qtbase/configure
if [ ! -e "$configure" ]; then
echo "$configure not found. Did you forget to run "init-repository"?" >&2
exit 1
fi

set -ex

mkdir -p qtbase
cd qtbase

exec "$configure" -top-level "$@"

Best regards

jsulm

@jhcuarta On what platform are you?
How did you get Qt source code?

jhcuarta

Sorry
I'm trying to install qt6 6.3.0, but I just modified the correct file, not the configuration file in the parent folder. Nevertheless I've installed version 6.2.4, having problems trying to finding correct installer. I'm using Ubuntu 22.04

jhcuarta

@jhcuarta When iI try to configure I got the following error
jason@jason:/home/jason/Documents/qt-everywhere-src-6.3.0$ ./configure

mkdir -p qtbase
cd qtbase
exec /home/jason/Documents/qt-everywhere-src-6.3.0/qtbase/configure -top-level

But how to ? Particularly, this annoying QtWebEngine?
I mean: how to disable the module QtWebEngine while building Qt from source (say: qt-everywhere-src-6.5.1) ?

Cheers

SGaist

@jiapei100 either delete the folder from the sources or use the --skip webengine option of the configure script. If you want to save time and space, only build the modules that you are actually using. You can always add others at a later stage if needed. Also, don't build the tests and examples.

First, make sure you have all the necessary dependencies installed on your system. You can use the apt package manager to install them. Check the Qt documentation for the specific dependencies required for your version of Qt. Once you have the dependencies in place, download the source code for Qt and extract it to a directory of your choice. Then, open a terminal and navigate to the extracted directory. Next, you'll need to configure Qt with the appropriate options for static building. The configure script provides several flags to enable static building, such as -static and -static-runtime. You may also need to specify the path to the static version of any external libraries you want to include. After configuring, run make to start the build process. This may take a while, depending on the speed of your system.
