Static compiling

I can't get a program (ices2) that uses libxml2 to compile
statically
with this library. It fails in "./configure"
process exposing this in
config.log:

configure:20640: gcc -o conftest -g -O2

I tried building libxml2 with --disable-shared and it was
doing the
same as with the normal system library. I did the same on 3
different
computers without much more success (two of them running
Slackware and
the other under Ubuntu).

Would this be related the way ices2 implements libtool ?
Should I recompile libxml2 in another way ?

  No idea, I always compile statically in my devel tree and
never saw this
when linking xmllint statically for example. Check with your
OS/distro
they must know about it.

  If the application tries to link statically all the stack
including
the libc, then it can be a problem, and I guess it's what is
being raised in
the warning. The fact that libxml2 uses the resolver trigger
this, but
fundamentally compiling the whole application static is
asking for troubles
especially for a large app.

In the case I'm concerned about, dynamic linking shouldn't
be used
since it's for an embedded system with a little memory
available.
Since the app isn't too big, it's propably the best thing to
do.

So from what you say, I can understand that the error comes
from the
way the "configure" script works.

Basically, what I do is:
LDFLAGS=-static ./configure

and then, it stops at:
checking for XML configuration
checking for xml2-config... /usr/bin/xml2-config
checking for xmlParseFile... no
configure: error: Unable to link with libxml
