The '''GNAT Modified General Public License''' (short: '''Modified GPL''', '''GMGPL''') is a version of the [[GNU General Public License]] specifically modified for compiled units and for the [[wikibooks:Ada Programming/Generics|generic feature]] found in the [[Ada programming language]].

The modification is as follows:

:As a special exception,  if other files  instantiate  generics from this unit, or you link  this unit with other files  to produce an executable, this  unit  does not  by itself cause  the resulting  executable  to  be covered  by the  GNU  General  Public  License.  This exception does not however invalidate  any other reasons why  the executable file  might be covered by the  GNU Public License.

The [[GNAT]] Ada compiler can automate conformance checks for some GPL software license issues via a [[compiler directive]]. Use <code>'''pragma License (Modified_GPL);'''</code> to activate the check against the Modified GPL.  The GNAT Reference Manual<ref>{{ cite web | url = https://gcc.gnu.org/onlinedocs/gnat_rm/ | title = GNAT Reference Manual | accessdate = 2010-07-21 }}</ref> documents the License<ref>{{ cite web | url = https://gcc.gnu.org/onlinedocs/gnat_rm/Pragma-License.html | title = Pragma License | accessdate = 2010-07-21 }}</ref> pragma along with other compiler directives.
