Re: Gawk 3.2.1 on HP-UX

[Mike Langas]

Michael,

Your suggestion works.  I think getting multibyte support to work might be
fairly straight forward however.

I did some research into the issue and found that to get full multibyte support
to work on HP there are a few things that need to be done.

1) define UNIX_STD=98 in the environment.
2) compile with the macro -D_XOPEN_SOURCE=500
3) with gcc, explicitly link with the object file unix98.o

I'm fairly sure I did the first two steps correctly.  The compile makes it much
further before I get errors.  I'm also fairly sure that I'm not correctly
linking with the unix98.o object.  It's times like this that I wish I had more
development experience ;-/

If you can tell me how get unix98.o used with the linker, I'll give it another
try.

Thanks again,

Mike
