new problems with win32ada

[Alessandro]

Help please!

I've compiled win32ada with patch and renaming win32ada.a to
libwin32ada.a,
gnatlink gives me a lot of  "undefined reference to " (examples
undefinite reference to sendmessage, invalidaterect etc.) etc.. Why?

Thanks in advance,

The Windows/NT operating system is build up of DLL's. The most basic
one, kernel32.dll, is automatically linked in. Others need to be 
linked in specifically. The Win32 documentation will tell you in what
DLL a given function is located. Than you need to link with the import
library for that DLL to use it.

Note that to compile a GUI program, you also have to add specific
linker instructions.

If you download the basic Win32ada example from my homepage you
can see how this is done.

Note that you must have a valid SDK license to legally use the Win32ada
bindings.

The SDK license should come with everythingt you need in the event it is
not already installed on your system.
