Build failure: Qt 5.15.5 on Ubuntu 22.04

Robert Hairgrove

Don't know why this fails. Here is the command line I used on Ubuntu 22.04 building from fresh sources installed from the file qt-everywhere-opensource-src-5.15.5.tar.xz :

./configure -opensource -confirm-license  -system-sqlite -system-zlib -icu > qt_configure_output.txt

Output from that command (saved in file qt_configure_output.txt:

+ cd qtbase
+ /home/bob/code/qt-everywhere-src-5.15.5/qtbase/configure -top-level -opensource -confirm-license -system-sqlite -system-zlib -icu
Creating qmake...

(... the rest was not saved to the file, but no errors were reported...)

Any help appreciated.

Hi,

Do you have any discrepancies with the dates of the generate files ?

By the way, you should consider using out of source builds so in case of an issue you can simply nuke the build folder and start from scratch more easily.

@SGaist Thank you ... building Qt out-of-sources was successful. I found this link which was very helpful in explaining how to do it:

https://gist.github.com/black13/3a55ed9afb5ba9ab5119ebd271a2aaa5

I saw another reference to this in the Qt documentation, but can't remember exactly where I saw it (EDIT: this was at the very bottom of the previous web page: https://doc.qt.io/qt-5/linux-building.html).

Now I was able to easily install both a debug and a release version of Qt with this method by setting different -prefix arguments.
