Subject: Re: Followup on HPUX build issue


Thanks, I will try that out.

There are some other problems with the ruby build you should
know about.

First off, the link is not given CFLAGS or LDFLAGS, so I
must set CC to not only define the compiler, but define
all of the other flags I need during the link.  I need
to pass in mainly directives to find shared libraries
because my shared libraries do not exist in paths that
exist in ldso.conf.

So, because my libraries are not found by the system, and ruby
performs its link with CFLAGS or LDFLAGS, I have to do
something ugly like this:

-----
# This one rejects CFLAGS and LDFLAGS during link, and links with CC
# So, I'm putting CFLAGS into CC
export CC="$CC $CFLAGS"
-----

This also causes problems when trying to build a 64-bit ruby on
HPUX 11.00 because if +DA2.0W is not seen on the command line
when performing a link the ansi c compiler will invoke
the 32-bit linker.  CFLAGS or LDFLAGS (preferably the later)
really should be sent in with the link.

Also, the ruby build on HPUX falsy detects several other
libraries.  Here is some perl in my little build script
that, after the configure, removes these false lib
dependencies.  Note, that the problem you gave me a
patch for cannot be fixed in this manner because the Makefile
with the problem is not generated until runtime, and we
could not figure out where we needed to jump in and
change the meta-build infrastructure.

Here's the perl:
    perl -pe 's/\-ltinfo//g ; s/\-lsocket/-lnsl/g ; s/\-lsun//g ; s/\-lutil//g
; s/\-DHAVE_OPENPTY//g' -i.bak `find . -name Makefile`
### This points to more bad configure checks?  Note, on HPUX the symbols found
lin -lsocket are really found in -lnsl.

    perl -pe 's/have_library\("tinfo", "tgetent"\) or have_library\("termcap",
"tgetent"\)//g' -i ext/curses/extconf.rb
### We couldn't find these libs on HPUX.  They don't seem to be in ncurses.
    perl -pe 's/have_library\("sun", "getpwnam"\)//g' -i ext/etc/extconf.rb
### Not sure what is firing -lsun in configure.
    perl -pe 's/have_library\("socket", "socket"\)/have_library("nsl",
"socket")/g' -i ext/openssl/extconf.rb
### -lsocket -> -lnsl

Any sort of patching you can do to make this build go more
smoothly on HPUX is greatly appreciated.  I'm very thankful
for the patch you gave me so far.  I'm very happy to test
anything out you'd like me to test.  Since you've fixed one
problem I figured I'd report the rest that we found.  I think
this covers all of the HP-UX and non-hpux issues that we found.
