HOWTO:  Build GnuPG on OS X

by Gordon Worley <redbird@rbisland.cx>

Version 1.6 (16 Sept 2001)

Introduction:

This document describes how to build GnuPG on Mac OS X.  The process
is pretty much the same as normal, but requires some extra effort to
get around OS X's 'features'.  For the latest version of this
document, check the Mac GPG Web site <http://macgpg.sourceforge.net/>.


How To:

Begin by downloading and verifying the GnuPG archives from
<http://www.gnupg.org/>.  Also, get egd while you're there.  Then, you
need to download the three patches found on <http://macgpg.sf.net/> for
OS X and verify them.

Now, install egd.  Just follow the instructions that came with it.  Or, if
you're feeling really crazy, you can try to have EGD run from start up.  To
do this, you'll need root access to the machine.  Follow the instructions in
the EGD module of the Mac GPG CVS tree.

Next, copy the two patches into the GnuPG folder the archive you
downloaded created when expanded.  To apply them, say:

patch -p 1 < gnupg-1.0.6-darwin-asm.diff
patch -p 1 < gnupg-1.0.6-darwin-configure.diff

This will apply both patches at once.  Look at the diff files for
details on what they do.  Thanks to Jeremy Cooper <jeremy@baymoo.org>
for the asm patch.

When you run configure, you need to make sure you have the proper
options set.  If you have EGD running from startup, be sure to use the 
EGD socket at /var/run/entropy.  Run configure as such for best results:

./configure --enable-static-rnd=egd --with-egd-socket=~/.gnupg/entropy
- --with-included-gettext

If you want, now is the time to apply the last patch that will make mlock
work.  Be warned, it may not work, especially if you do do something
different durring configuration.  At the worst, you'll have to manually
change the files rather than just patch them.  Here's what to say:

patch -p 1 < gnupg-1.0.6-darwin-secmem.diff

Thanks, Laurie <laurieb@mac.com>, for the patch.

Now, all you have to do is type 'make' and then 'sudo make install'.

Also, it's probably a good idea to run make check before you install,
to make sure that your system will be safe on which to run GnuPG.  If you
get a lot of failed tests, you may not have started EGD correctly.  Make
sure it is connected to the socket you specified to configure.

Thanks:

A big thank you to Sebastian Hagedorn <Hagedorn@spinfo.uni-koeln.de>
and Bryan Blackburn <blb@pobox.com>, who figured out what was wrong
with configure and provided fixes.  Thank you to Jeremy Cooper
<jeremy@baymoo.org> who did the asm patch.  More thanks to Laurie Brown
<laurieb@mac.com>, who not only came up with the EGD at starup stuff but
also the secmem patch.
