Try using the Debian package as a reference. AFAIK it builds fine on
AMD64. (nothing goes into "testing" without being built on all
relevant architechtures first).

  http://packages.debian.org/testing/comm/asterisk-oh323

The tarball and diff are at:

  http://ftp.debian.org/debian/pool/main/a/asterisk-oh323/asterisk-oh323_0.6.6pre3.orig.tar.gz
	http://ftp.debian.org/debian/pool/main/a/asterisk-oh323/asterisk-oh323_0.6.6pre3-3.diff.gz

This is still 0.6, but I figure the required changes are similar enough.
Let's have a look...

It turns out that the file "in the patch" basically include (besides the
usual debian files) the following patch:

diff -urNad asterisk-oh323-0.6.6pre3/Makefile /tmp/dpep.3hXNkc/asterisk-oh323-0.6.6pre3/Makefile

 ifdef  HAS_OH323MODS
 CPPFLAGS += -DHAS_OH323MODS
 CFLAGS += -DHAS_OH323MODS

So it basically adds -fPIC but to the CFLAGS. I have no amd64 machine to
play with, but most of the amd64 patches I recall had something to do
with -fPIC.


Is this relevant to 0.7? who knows? The h323 channels won't get very far
if they'll continue depending on a specific version of the-beast^Wlibh323.
