[mkgmap-dev] License issue in mkgmap & splitter source: GPL-2 (v2 only) incompatible with GPL-3 (v3 only)

Sat Jul 1 13:29:12 BST 2017

Several source files are licensed under the GPL-2 which is incompatible
with GPL-3 source in splitter.

To combine GPL-2 code with GPL-3 code, the GPL-2 code needs to be
license under the GPL-2+ (v2 or later), or dual-licensed under the GPL-2
(v2 only) or GPL-3 (v3 only).[0]

The mkgmap source files in question:

 src/uk/me/parabola/mkgmap/filters/MustSplitException.java
 src/uk/me/parabola/mkgmap/reader/MapReader.java

The splitter source files in question:

 src/uk/me/parabola/splitter/tools/BitReader.java
 src/uk/me/parabola/splitter/tools/BitWriter.java
 test/func/ArgsTest.java
 test/func/Base.java
 test/func/SolverAndProblemGeneratorTest.java
 test/func/lib/Args.java
 test/func/lib/Outputs.java
 test/func/lib/TestUtils.java
 test/uk/me/parabola/splitter/tools/TestBitReader.java

Steve & Gerd, can you relicense the code to GPL-2+ (v2 or later) or dual
license those files as GPL-2 (v2 only) or GPL-3 (v3 only)?

This issue prevents the update of the mkgmap packages in Debian.

Kind Regards,

Bas
