I'm new to linux. Is it poosible to use GTK4 developed apps in older version like ubutnu 16,18 etc.
Tried executing a compiled (ubutnut 22)Gtk4 binary into ubuntu 20.
/hello: error while loading shared libraries: libgtk-4.so.1: cannot open shared object file: No such file or directory
ldd gtk4_app_name Find out what dynamic libraries are being linked to your GTK4 app. Share more information on your files, pwd what directory name. echo $PATH
readelf -s gtk4_app_name ls -l
the gtk4 app is using a newer version of the library. Install a newer version of the library to replace the old library.
su root password: cd /lib ln -s libgtk-3.so.1 libgtk-4.so.1 # check on the order Create ln -s TARGET LINKNAME Symbolic Link from newer version name libgtk-4.so.1 to older presently existing library name /lib/libgtk-3.so.1 In the 1st form, create a link to TARGET with the name LINK_NAME.
Realize the mixing and matching library names is BAD POLICY. Better to update applications to match libraries so you don't create random runtime problems. Open a terminal, read the manual details on symbolic linking man ln https://manpages.ubuntu.com/manpages/focal/en/man7/symlink.7.html
