# Note, for linkage=static, libclixon is linked twice:
# First static when building:
#    libclixon_backend, libclixon_cli, libclixon_restconf and libclixon_netconf
# Second in this Makefile dynamic using -lclixon
# This means global variables used in plugin code is in separate domains and will not work
# Dont know enough about dynamic/static linkage to fix it.
# One way is to not use global variables in libraries, but there are still some, eg in error
# and log modules
