After a couple of catastrophes, I reinstalled my operating system ... and eventually rebuilt gimp. The gcc-7 gimp failed to open with a gimp: symbol lookup error: gimp: undefined symbol: gimp_convert_dither_type_compat_get_type The gcc-6 gimp works fine. Were my problems related to gcc-7? carol _______________________________________________ gimp-developer-list mailing list List address: gimp-developer-list@xxxxxxxxx List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list List archives: https://mail.gnome.org/archives/gimp-developer-list
