# svr5 hints, System V Release 5.x (UnixWare 7)

# Originally taken from svr4 hints.sh 21-Sep-98 hops@sco.com
# which was version of 1996/10/25 by Tye McQueen, tye@metronet.com
# Use Configure -Dusethreads to enable threads.

# However there is a dbm library built from the ucb sources outside ucblib
# at http://www.sco.com/skunkware (installing into /usr/local) so if we
# detect this we'll use it. You can change the default

If you wish to use dynamic linking, you must use
LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH
or
setenv LD_LIBRARY_PATH `pwd`
before running make.
If you are using shared libraries from /usr/local/lib
for libdbm or libgdbm you may need to set
LD_RUN_PATH=/usr/local/lib; export LD_RUN_PATH
in order for Configure to compile the simple test program
