Re: [Libguestfs] [PATCH 0/3] hivex: Improve OS X support

This patch series improves, but does not complete, OS X support for
hivex. There are several outstanding issues before hivexml and hivexsh
can run:
* hivexsh uses open_memstream, which doesn't exist in OS X as near as I
can see. Unfortunately, I'm inexperienced with autoconf, so I'm not
sure how to employ AC_CHECK_FUNCS([open_memstream]) to conditionally add
'sh' to the Makefile.am's SUBDIRS.
You need to use an automake conditional. It'll be something like this
(not tested):
AM_CONDITIONAL([HAVE_HIVESH],[test "x$HAVE_OPEN_MEMSTREAM" = "x1"])
and then in Makefile.am:
if HAVE_HIVESH
SUBDIRS += sh
endif
There are plenty of examples of this in the libguestfs source, eg.
have a look at HAVE_PERL in configure.ac and Makefile.am.
* The check for libxml fails, because PKG_CHECK_CONFIG doesn't
exist on
OS X. I think it would be better to use AC_CHECK_FUNCS on some of the
libxml functions, but again, I'm not too hot with autoconf and automake.
Grumble. OS X sounds a bit broken if it doesn't include pkg-config
files (*.pc). Is libxml2 provided in the base OS X or is this coming
from an outside project like MacPorts?
* hivexml has the following run-time failure:
dyld: lazy symbol binding failed: Symbol not found: _iconv_open

Missing libiconv on OS X?? I don't really know about this one.
