Re: how to build gcc-3.3.2 in OpenBSD ports tree?

[Jonathan Thornburg <jthorn_(_at_)_aei_(_dot_)_mpg_(_dot_)_de>]

In the thread rooted at
<http://monkey.org/openbsd/archive/ports/0401/msg00106.html>,
I asked various questions about trying to build gcc-3.3.2 (i386 system,
C, C++, and F77 only) from the OpenBSD 3.4-current ports tree.

I've now succeeded.  I'd like to thank all who replied to my messages,
both on the list and in private E-mail.  For the benefit of others,
here are some highlights of the solution:

* It's essential to use the *right* cvs options to move /usr/ports
  (or in my case just /usr/ports/lang/egcs/) from 3.4-stable to -current.
	[The docs warn against selectively upgrading part of
	the ports tree like this; in hindsight I should perhaps
	have created a separate /usr/ports.current/ hierarchy
	and left /usr/ports at -stable.  Maybe next time...]
  I at first omitted the -A (needed to move from a CVS branch back
  to the CVS mainline), and then omitted the always-essential -Pd.
  Bad, bad...

* It's essential to tell the egcs port what languages you *don't*
  want if they're marked as broken:
	# make MAKE_OBJC=No MAKE_ADA=No MAKE_JAVA=no CDROM_SITE=/tmp
  Looking at /usr/ports/lang/egcs/snapshot/Makefile was ++helpful.

* After I got gcc installed, I had some trouble figuring out how to get
  g++ and g77 as well.  I eventually realised these are *subpackages*,
  not flavors, after which recursive grepping turned up the right
  settings in the Makefile and all was well:
	# setenv SUBPACKAGE -g77
	# make install MAKE_GXX=Yes MAKE_FORTRAN=Yes MAKE_OBJC=No MAKE_ADA=No MAKE_JAVA=no CDROM_SITE=/tmp
	# setenv SUBPACKAGE -c++
	# make install MAKE_GXX=Yes MAKE_FORTRAN=Yes MAKE_OBJC=No MAKE_ADA=No MAKE_JAVA=no CDROM_SITE=/tmp
  (I suspect that the explicit setting of MAKE_GXX and MAKE_FORTRAN
  were actually unnecessary here.)

A followup question: which piece of documentation should I have read
to learn about the SUBPACKAGE settings?  'cd /usr/ports; make search key=g77'
told me the '-g77' string, but where should I have looked to realise
this was a subpackage?

ciao, and many thanks to Mark Espie for keeping this port up to date,
