Hi André,

Thanks for reporting this.

QtSql depends on sybdb (freetds) which depends on gnutls. Even though 
you are using only QODBC, the dependencies of all the sql drivers have 
to be satisfied. This is because our Qt configuration builds the sql 
drivers into QtSql rather than as plugins.

Some time ago the freetds configuration was changed to use gnutls 
instead of openssl, but I neglected to add gnutls to SYBASE_LIBS in qt.mk.

I've fixed this here:
http://hg.savannah.gnu.org/hgweb/mingw-cross-env/rev/fb7112048cbd
Also made the test program depend on QtSql so this type of linking 
problem will be caught.

Could you let us know if this works for you?

regards,

Mark
