Installation of Qt4.7 on Debian Buster distribution

PatMooc

Hello,

I'm currently working on a Qt4.7 projet compiled on a Debian Lenny distribution.
I encountered library incompatibility for communicating with an USB HID reader.
I tried a test project for this communication on a Qt5 projet on a Debian Buster distribution : it is ok
The same test project on my Qt4.7 project fails.
Thus, before moving all the project to a newer version of Qt (5 or 6), I tried to install the Qt4.7 on the Debian Buster distribution. But compilation fails at 'make' step.

Here is what I have done :
1/ I have downloaded Qt4 from here : https://download.qt.io/archive/qt/4.7/
My Qt4 version is 4.7.4 (with QtCreator 2.2.0) => qt-everywhere-opensource-src-4.7.4.tar.gz
2/ I then followed steps given here : https://doc.qt.io/archives/qt-4.7/qt-embedded-install.html

3/ 'configure' step is ok and finished with following message :

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/Trolltech/Qt-4.7.4
To reconfigure, run 'make confclean' and 'configure'.

4/ I then run make :
root@pc-debian:/home/patrick/qt4/qt-everywhere-opensource-src-4.7.4# make

And after several minutes following error messages appear :

char name __flexarr; /* Name. */

And a few seconds after the end is :

make[1]: *** [Makefile:16430: .obj/release-shared/qfilesystemwatcher_inotify.o] Error 1
make[1] : on quitte le répertoire « /home/patrick/qt4/qt-everywhere-opensource-src-4.7.4/src/corelib »
make: *** [Makefile:206: sub-corelib-make_default-ordered] Error 2

Thus, it seems that there is a problem with "qfilesystemwatcher_inotify.cpp:364:33"

Is there any way to correct this in order to can install Qt4.7 into Linux Buster distribution ?

Thank you in advance for your answer.
Best Regards,
Patrick

@PatMooc You could try with latest Qt4 release (4.8.x, don't remember last number).

@jsulm : Thank you for your advice !

I have just downloaded corresponding version (4.8.7) an tried to install it.

Unfortunately, compilation also fails, but with another error message concerning another module :

Hi,

Why not use the Qt 4 version provided by your distribution ?
