Hi there, I keep getting these strange errors when building my documentation:

Error: no ID for constraint linkend: _Tutorial_.
Error: no ID for constraint linkend: _extenting_io_.
Error: no ID for constraint linkend: _Supported_Formats_.
Error: no ID for constraint linkend: _Supported_Formats_.

The file I'm trying to build is here:

http://gil-contributions.googlecode.com/svn/trunk/gil_2/libs/gil/io_new/doc/io.qbk

plus the jam file

http://gil-contributions.googlecode.com/svn/trunk/gil_2/libs/gil/io_new/doc/jamfile.v2

I read somewhere that I need to use two-pass processing but I don't
understand what means.

Any help is very welcome.

Thanks,
Christian
