EarthMate Userland Library

The project is now covered by the LGPL. There were some minor code cleanups made, along with an update of the documentation.

The primary changes are for Mac OS X. The changes include the addition of the Earthmate lt-20 device id to the codeless kernel extension, a Mac OS X link time fix, and some documentation updates.

This release handles the rare case where someone
is using either a partially patched 2.6.10 kernel
or a partially patched 2.6.9 kernel. In either
case, emul would be unable to release usbhid from
the target device and fail on the attempt to open
the device.

AC_FUNC_MALLOC was removed, as it was causing a
linker problem on Mac OS 10.4.1. A bug which was
causing a segfault with gpsd if using the "no
wait" flag (-n) on Linux systems has been
resolved. Along with other numerous bug fixes to
the library itself, the gpsd-2.25/emul release was
also updated to stable development source.

This release fixes a bug preventing functionality on big endian hardware. It also features support for DeLorme's Earthmate LT-20.
