$ erl -man io No manual entry for io
I have compiled and installed (with configure's prefix option) in /opt/erlang on Solaris 9, put the man page files just in /opt/erlang/man. Clearly this doesn't work. So I did some tracking with:
$ truss -o /tmp/output.txt erl -man io
(truss is like strace for Solaris; "strace" on Solaris is completely different thing.)
And found that the "/man" directory should live in /opt/erlang/lib/erlang/man.
"erl -man io" works now. It's in MANPATH and Windex is created -- so just "man io" would work just fine, but I just wanted to fix it anyway.
