Re: Ada and licensing

[anon@anon.org (anon)]

This pragma may give you some idea how Adacore and GNAT deals with 
this issue.

 pragma License ( Restricted ) ;

But if you link your code with "glibc" or the standard GPL "libgnat". it 
must not be licensed with the option of "Restricted". You must build 
your own "libgnat" version.

Also Note: There is a movement to have GPL license module only in Linux, 
            starting in Jan 2008. Not sure how Adacore or GNAT will 
            handle this.

 Pragma License
 Syntax:  pragma License ( Unrestricted | GPL | Modified_GPL | Restricted );

 This pragma is provided to allow automated checking for appropriate 
 license conditions with respect to the standard and modified GPL. A 
 pragma License, which is a configuration pragma that typically appears 
 at the start of a source file or in a separate  gnat.adc  file, 
 specifies the licensing conditions of a unit as follows:

 "Unrestricted"  => This is used for a unit that can be freely used 
                    with no license restrictions.

 "GPL"           => This is used for a unit that is licensed under 
                    the unmodified GPL, and which therefore cannot 
                    be with ed by a restricted unit.

 "Modified GPL"  => This is used for a unit licensed under the GNAT 
                    modified GPL that includes a special exception 
                    paragraph that specifically permits the inclusion 
                    of the unit in programs without requiring the 
                    entire program to be released under the GPL.


 "Restricted"    => This is used for a unit that is restricted in that 
                    it is not permitted to depend on units that are 
                    licensed under the GPL. Typical examples are 
                    proprietary code that is to be released under 
                    more restrictive license conditions. Note that 
                    restricted units are permitted to with units which 
                    are licensed under the modified GPL (this is the
                    whole point of the modified GPL).
