the comand line to compile IDL should looks like the following :
widl -I/usr/include/wine/windows/ \
- -h -H axvlc_idl.h -t -T axvlc.tlb -u -U axvlc_idl.c \
- axvlc.idl
+ -h -H axvlc_idl.h -t -T axvlc.tlb -u -U axvlc_idl.c axvlc.idl
NOTE: widl breaks compatibility with Visual Basic. If that is important
to you then you must use midl.
