Hm... Not sure what do you mean by this but...

Looks like you forgot to link with xmlsec-mscrypto library.
The xmlsec.exe application can either load it dynamically
or link against it statically. Probably some "defines" are
missing from your makefile.

Well, best advice I have is to use the makefiles included
in the xmlsec distribution. Otherwise, you are on your own
and your mileage may vary....
