# This script assumes that the Hamlib tarball has been extracted to the
# directory specified in $build_dir and that libusb-win32-bin-1.x.y.z has also
# been extracted to $build_dir and a libusb.pc file has been created.  The
# MS VC++Toolkit must also be installed.
#
# See README.build-win32 for complete details.

This ZIP archive contains a build of Hamlib-$RELEASE
cross-compiled for Win32 using MinGW under Debian GNU/Linux (nice, heh!).
The DLL has a cdecl interface for MS VC++.

This material is copyrighted. The library license is LGPL, and the *.EXE
files licenses are GPL.  Hamlib comes WITHOUT ANY WARRANTY. See LICENSE.txt
COPYING.txt, and COPYING.LIB.txt files.

Make sure *all* the .DLL are in your PATH, and you have read
the README.betatester file, especially the "testing Hamlib" section.

There's a .LIB import library for MS-VC++ in lib/msvc.  Simply #include
<hamlib/rig.h> (add directory to include path), include the .LIB in your
project and you're done. Note: MS-VC++ cannot compile all the Hamlib code,
but the API rig.h has been made MSVC friendly :-)

Patches, feedback, and contributions are welcome.

Please report problems, success to hamlib-developer@lists.sourceforge.net
