# This magic is a workaround for libsoup bug.
|
|
#
|
|
# We are linked against libsoup. If SANE backend goes unloaded
|
|
# from the memory, all libraries it is linked against also will
|
|
# be unloaded (unless main program uses them directly).
|
|
#
|
|
# Libsoup, unfortunately, doesn't unload correctly, leaving its
|
|
# types registered in GLIB. Which sooner or later leads program to
|
|
# crash
|
|
#
|
|
# The workaround is to prevent our backend's shared object from being
|
|
# unloaded when not longer in use, and these magical options do it
|
|
# by adding NODELETE flag to the resulting ELF shared object
