if there is a problem launching the software under OpenMandriva Lx 4.0, if you get an error of the type :
[kredge@OpenMandriva4 JustConsum]$ ./JustConsum
** (JustConsum:2409): ERROR **: 21:32:50.318: Unable to fork a new child process: Failed to execute child process "/usr/libexec/webkit2gtk-4.0/WebKitWebProcess" (No such file or directory)
Trace/breakpoint trap (core dumped)
So you have to install the package :
lib64webkit2gtk4.0_37 - GTK+ port of WebKit web browser engine
as well as its dependencies ...
