Re: 64bit HPUX problems

[ross . alexander]

This all relates to libtool-1.4e.

I have made changes to config.guess to detect hppa64 systems and
changed in libtool.m4 to add support for for that environment.  However,
I am getting a problem with hardcoded -rpath values.

The 64bit environment has

      hardcode_into_libs = no

but -R /usr/local/lib (for example) picked up in dependency libraries
gets carried though to the $deplibs value used in the link and
relink commands.

This looks like a bug, but could have been fixed in CVS.  If anybody
has come across this, I would like to get it fixed.

Cheers,

Ross

You can check CFLAGS. If they're using GCC, then have a separate case
statement to handle that:
  case "$CFLAGS" in
  *-DD64*)
    if test "$GCC" = yes; then
    else
    fi ;;
  *)
    ;;
  esac

You can also try compiling something and running file/odump/elfdump on
the result to test if the default is a 32/64-bit object file (I
imagine the output should be different for 32/64-bit executables).
I'm leaning towards checking $CFLAGS though.
