I tried to follow the HEIC support install instructions over here, but I catch a snag during at the ./configure step which stops the make command from doing anyting:
configure: error: Package requirements (glib-2.0 >= 2.15 gmodule-2.0 gobject-2.0 gio-2.0) were not met:
Package 'libffi', required by 'gobject-2.0', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables REQUIRED_CFLAGS
and REQUIRED_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
root@uServer:~/src/vips/vips-8.10.2# make;
make: *** No targets specified and no makefile found. Stop.
I have the installed and enabled ALL available Dev Tools and Nerd Tools, but still nada. I am not sure what to do next.
