[Mingw-cross-env-list] Xerces library problem

[tek]

Hi everybody,

I'm in the process of cross-compiling a project using Xerces (under 
Debian). I did:

$ make xerces

Seems to work, but:

$ ls -l usr/i686-pc-mingw32/lib/libxerces*

-rw-r--r-- 1 tek tek    8 Jul 11 04:11 usr/i686-pc-mingw32/lib/libxerces-c.a
-rwxr-xr-x 1 tek tek 1528 Jul 11 04:11 
usr/i686-pc-mingw32/lib/libxerces-c.la

Note the size fields. So, it did not work. Checking logs for xerces 
build, I noticed these lines of interest:

libtool: link: warning: undefined symbols not allowed in i686-pc-mingw32 
shared libraries
libtool: link: i686-pc-mingw32-ar cru .libs/libxerces-c.a
libtool: link: i686-pc-mingw32-ranlib .libs/libxerces-c.a

Searching on the web led me to the assumption that -no-undefined (or 
--no-undefined) should be given to the linker options when building 
Xerces may resolve the issue. The fact is... I don't really know how in 
the context of mingw-cross-env. I could hack a bit for this... but TBH, 
that's not why I decided to mail here.

I just wonder: is something broken in mingw-cross-env with Xerces or did 
I miss something? My project also makes intensive use of SDL without 
problems (well, at least no error reported about it either in 
mingw-cross-env and my project link time) and OpenGL with minor problems 
(it mostly has to do with GL shader calls, I'll deal with it in time). 
But obviously, object files using Xerces lead to undefined references.

My second question is: do you think I should use the Debian package 
mingw32 instead of mingw-cross-env? Are there some drawbacks (besides 
the fact I would have to deal manually with a few builds)?
