           Summary: neon config fails libxml/parser.h: libxml2 requires, but
                    not dependent on, libiconv
           Product: buildroot
           Version: 2010.02
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: mjhammel at graphics-muse.org
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


Running configure for neon:

/usr/include/libxml2/libxml/encoding.h:136: error: expected
specifier-qualifier-list before 'iconv_t'

Checking encoding.h, iconv.h is included only if LIBXML_ICONV_ENABLED is set:

#ifdef LIBXML_ICONV_ENABLED
#include <iconv.h>
#endif

There are no buildroot options to set this so it must be on by default in the
libxml2 build which means that libxml2 should be dependent on libiconv, but it
currently is not.  

Test run: 2010-03-22
Buildroot version: buildroot-2010.02 on Fedora11

The problem rather seems to be that neon somehow end up looking at your host
includes, instead of the ones in staging/usr/include.

I cannot reproduce it here, please provide more details about your setup (and
your .config)

Created an attachment (id=1465)
 --> (https://bugs.busybox.net/attachment.cgi?id=1465)
Buildroot config 

I build the cross compiler first, separately, using buildroot.  Then I build
the rootfs.  The xcc source and build trees are completely separate from the
rootfs source and build trees.  I have a metabuild (Makefile, patches, etc.)
that does all this for me.  The metabuild copies over the buildroot tarball to
the build tree, unpacks it, applies patches, copies in the config file (which
is a template that is patched by the metabuild so output goes to the correct
location), and then compiles the rootfs.  The patching of the config file is
done so that all developers can build the project the same way without hard
coded locations in the config file.

My fix to this problem was to enable libiconv in the config file, as shown in
the attachement.

If you'd like to see the metabuild Makefile and includes let me know and I'll
attach them separately.

--- Comment #3 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com>  ---
Even though I haven't reproduced the particular problem reported by this bug, I
think commit
http://git.buildroot.net/buildroot/commit/?id=4a2dabe9d53e6c361ecdeaba0431ef74a9ad297c
might fix the problem. Don't hesitate to reopen the bug if you can still
reproduce it with the latest Buildroot git.
