[Linphone-developers] linphone compile error on ubuntu 18 with Qt5.12

[Mario Pink]

Hi,

when i try to compile the git version of linphone i always get the
following error you can see below.

The sdk could successfuly be compiled but the qt app doesn't.

any suggestions?

What i find out so far during the create process the
linphone-app/src/linphone-qt-stamp/linphone-qt-configure file could not
be created.


Log output: System: Ubuntu 18.04, Qt 5.12.5 (sources compiled an env
correctly set)
