# To support dynamically loaded modules libnxt library must be a shared
# object itself because an application linked with static libnxt library
# may lack code required by the modules. Dynamic linkers allow to specify
# relative path in SONAME library entry or in RPATH executable entry.
#
# Solaris 7, Linux 2.2, and FreeBSD 7.3 support $ORIGIN variable.
# MacOSX supports @executable_path variable.
# NetBSD does not support $ORIGIN variable.
#
# "ar -r" is enough to create a static library, ranlib is surplus.
# "ar -c" disables the "creating archive" warning.
