I don't think it would help much. You could do the Wireshark

if you are really ambitious, single-step through buildGenericCmd() in

should eventually bomb out somewhere with the
SML_ERR_XLT_INVAL_SYNCML_DOC error.
I built some debug printing into the SMLTK a long time ago, however the problem is that
there was no easy way to pass a debug logger handle down into the C-only toolkit to
actually output it. And because just printing it on the console was no option for a shared
library, the corresponding output macro SMLERRPRINTFX() is doing nothing.
To debug a specific case however, you might want to temporarily define that macro, for
example just map it to printf(), in src/syncml_tk/src/sml/xlt/all/xltdec.c:
#define SMLERRPRINTFX(lvl,m) printf m
If you have access to the stdout produced while the sync runs, you'll get much useful
information in case of a decoding error, including some context dump of the text being
parsed, clear text error message and the routine name that caused the error.
Patrick, maybe there is a better way in SyncEvolution context than just printf() that
could be made into a log option for debugging decoding problems?
