You're being awfully selective in your reading. Section 6a is immediately preceded by a statement which says: "Also, you must do one of these things:" 6a is but one of 5 choices. Those choices are: "b) Use a suitable shared library mechanism for linking with the Library." "c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution." "d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place." "e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy." Pick any one of those options you like that doesn't involve shipping source code. Using standard shared libraries is a "suitable shared library mechanism". Also, the LGPLv3 in section 4d.1 specifies the same "Use a suitable shared library mechanism for linking with the Library." This is more relevant, since GMP is licensed under v3 and not v2.1. -- Nick _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
