How can I configure QT source code if it can't detect default installed OpenGl ES?

The one provided by my distro is outdated, very outdated. I downloaded the "offline installer" because there are times I'm without internet.

The offline installer already provides you with a pre-built Qt.

How do I activate it? In tutorial they where explaining how to build from source only... From what I remember. I kinda read the readme file... And the instruction in readme file is:

./configure -prefix $PWD/qtbase <license> -nomake tests
    make -j 4

Did you actually ran the offline installer ?

There is no runnable binary, for what I can see. Or I don't know the name... There are many modules here.

@UltraBurstXD The offline installer is just one file. But offline installers are not available anymore for open source users (without commercial license). So, what exactly did you download?

UltraBurstXD · 15 Dec 2020, 08:03

I downloaded here: https://www.qt.io/offline-installers

@UltraBurstXD As I said: offline installer is just one file. Make it executable (chmod u+x OFFLINE_INSTALLER_FILE) and execute it. No need to build anything.

@jsulm I don't know name of offline installer... It's my first time using qt... perhaps should I specify qt modules path to qt creator? And configure the environment variables?

@UltraBurstXD Lets do one step after another: you downloaded the offline installer, is that correct? Like http://download.qt.io/official_releases/qt/5.12/5.12.10/qt-opensource-linux-x64-5.12.10.run

UltraBurstXD · 15 Dec 2020, 08:23

Yes, I did and extracted the files to home. As seen:

The archive name is qt-everywhere-src-5.15.2.tar.xz

@UltraBurstXD You did NOT download the offline installer, you downloaded the source code. Can you please post the exact file name you downloaded?

UltraBurstXD · 15 Dec 2020, 08:36

It turns out I downloaded Qt 5.15.x Source Packages... My internet data plan... And it can't configure because of OpenGL.

@UltraBurstXD Didn't you want to install Qt using offline installer as @SGaist suggested? So, what do you want to do now? It is much much easier to install prebuild Qt than to build it by yourself. I suggest you use offline or (better) online installer to install prebuild Qt.

Then lets go from scratch:

cd /somewhere_NOT_in_Qt_source
mkdir build_Qt
cd build_Qt
/path_to_Qt_sources/configure -nomake tests -nomake examples

What do you get now ?

You cannot make a shadow build from a source tree containing a previous build.
Cannot proceed.

SGaist · wrote on 15 Dec 2020, 08:57

I guess you kept the original archive, if so, just nuke the sources and extract them again. Then redo the procedure suggested above.

New error:

Please show the exact line you use.

UltraBurstXD · wrote on 16 Dec 2020, 09:17

Which line?

~/qt_source/configure -nomake tests -nomake examples

That one?
