If you are a developer and feel bored all day, than it would be cool if you are going to help develop this library. Therefore you can register yourself at the mailinglist (see homepage above), where all developers can keep in contact.
Installation (Linux):
By installing this lib (by typing ./configure, make, make install), three static libs are installed into /usr/local/lib/canopen: libcanopen.a, libobjdict.a, libarbracan.a. Also the .h-files are installed into /usr/local/include/canopen and C++ headers are installed into /usr/local/include/canopen/cpp (they contain a extern "C" {...} directive, so your linker can resolve symbols.
If you're going to create your own slavelib-device, just link the libs to your project and tell the compiler about the includepath. This is done by the flags:
-I/usr/local/include/canopenslavelib/ /usr/local/lib/canopenslavelib/libcanopen.a /usr/local/lib/canopenslavelib/libarbracan.a /usr/local/lib/canopenslavelib/libobjdict.a
or (by using C++):
-I/usr/local/include/canopenslavelib/cpp /usr/local/lib/canopenslavelib/libcanopen.a /usr/local/lib/canopenslavelib/libarbracan.a /usr/local/lib/canopenslavelib/libobjdict.a
