Unable to install gobject-introspection - symbol lookup error: and undefined symbol: g_unicode_type_get_type

I tried to compile Gtk4, and download gobject-introspection 1.30, 1.40, 1.50, 1.64.1. All failed with the same exact error except the last one that produced another error.

Errors for gobject-introspection 1.30, 1.40, 1.50,

I solved that problem finding the solution here :

You're probably missing the development package. The package name varies by distribution, but it's the one containing /usr/lib/pkgconfig/gobject-introspection-1.0.pc (or /usr/lib64/pkgconfig/gobject-introspection-1.0.pc for some 64-bit distros):

Fedora, CentOS, RHEL, etc.: gobject-introspection-devel

Debian,Ubuntu, Mint, etc.: libgirepository1.0-dev Arch: gobject-introspection

FreeBSD: gobject-introspection

Cygwin: libgirepository1.0-devel msys2:

mingw-w64-x86_64-gobject-introspection and/or mingw-w64-i686-gobject-introspection
