Hello all, > > Regarding linking to Apache-licensed libraries, what is your consideration? > What procedure would you recommend and why? >
Free Software Foundation defines, which software licenses are considered GPL compatible in order to prevent uncontrolled linking of non GPL modules with the GPL modules. The copyright holders of the program are however allowed to change the program license by introducing following exception clause here: "In addition, as a special exception, the copyright holders of ABC give you permission to combine ABC program with free software programs or libraries that are released under the GNU LGPL and with code included in the standard release of DEF under the XYZ license (or modified versions of such code, with unchanged license). You may copy and distribute such a system following the terms of the GNU GPL for ABC and the licenses of the other code concerned, provided that you include the source code of that other code when and as the GNU GPL requires distribution of source code. Note that people who make modified versions of ABC are not obligated to grant this special exception for their modified versions; it is their choice whether to do so. The GNU General Public License gives permission to release a modified version without this exception; this exception also makes it possible to release a modified version which carries forward this exception." This text can be applied to any software module. But it is considered to be a license change, that means that all copyright holders have to agree on the change to make it legal. As it is obviously clear that using of additional components covered by the Apache License is helpful, I would like to go this way provided that we can identify all copyright holders that means everybody who has significantly contributed to the program. The same considerations are valid for HotEqn.jar too. Do you know who are all those people and whether all of them are still alive and may be contacted?
