3) Change the Makefile to do the following test instead:
if [ "$(prefix)" = / -o "$(prefix)" = "" ];
Try this:
if [ x$(prefix) = x/ ]
That is recommended way to test varaibles when you aren't sure that it allways
have an asigned value.
Yes, but we also have to test for "x$(prefix) = x" otherwise mandir
isn't set correctly. Here's the full decision tree with $(prefix) expanded:
if [ ""/man = ""/man ]; then
if [ "" = / ]; then
echo /usr/share/man;
else
echo ""/share/man;
fi;
else
echo ""/man;
fi;
Note that we fail the second test, hence setting mandir=/share/man. If
we change the second test to:
if [ "" = / -o "" = "" ];
we end up setting $(mandir) to "/usr/share/man" whether prefix is "" or
"/" on the command line.

Matt.
