DFSG compatible No
FSF approved No[1]
OSI approved Yes

The Sybase Open Watcom Public Licence is an open source license that has been approved by the Open Source Initiative.[2] It is the licence under which the Open Watcom C/C++ compiler is released.

The license has not been accepted as "free" under the Debian Free Software Guidelines, due to controversy about the license's termination clauses.[3][4]

The Fedora project also considers the license as non free. [5]

The Free Software Foundation has stated that the license is not free as it requires the source to be published when you "deploy" the software.[1]


The draft of version 2.0 of the Licence was published on 20 January 2004. This version incorporated changes from Apple and made the licence less specific to OpenWatcom.[6]
