So you have "libxml2-2.8.0" here, but "libxml2-2-6.30" in CFLAGS and
LDFLAGS later...

You should not need ANY of that, except for CFLAGS="${OMAP3_FLAGS}".
libsoup should get the correct CFLAGS, LDFLAGS, and LIBS for glib and
libxml2 based on the value of PKG_CONFIG_PATH you set above. If it's not
getting the right values, then that's your real problem, and you need to
fix that.


Two notes on specific errors:

What version of gcc are you using? There's a
"G_GNUC_BEGIN_IGNORE_DEPRECATIONS" declaration in soup-value-utils.c
that ought to be suppressing these warnings.

This suggests that <libxml/tree.h> was found (since there was no message
about not finding it), but it did not contain a definition for
xmlNewChild. Which is weird...
