libxml2-native including system zlib

["Jader H. Silva" <jader@2mi.com.br>]

Hello again.
I'm trying to build an i586 x11-image, but I cannot pass libxml2-native
do_compile task, it seems it includes the host libz.h.

Error:

Found gzopen in libxmlIO.c. gzopen is defined as gzopen64
in /usr/include/zlib.h, also, if i run make CFLAGS+=--verbose, I get

-isystem /usr/include is set on cc1, so it invalidate include
path /home/jader/oe/build/conf/tmp/staging/i686-linux/usr/include (where
zlib.h is).



Is it correct for Makefile to use my system GCC ?
Can anybody help me to compile it correctly?


Thanks in advance
