In Response To: RE: How to develop datablade under gcc/WinXP? (Jean Anderson )

Dear Sirs,
Is it possible to test a compiler and runtime environment
without controling of a code?
This is the guilty datablade.

#include <mi.h>
mi_lvarchar * hello_world () {
mi_lvarchar *retval=NULL;
retval = mi_string_to_lvarchar("Hello World!");
return retval; }

Donald. Thank you. This not work but I tried this example straightforvard. I
will be to analize your example more.
Pawel.
