See instlib.txt in the ArgyllCMS source on how to create the instlib.zip archive. To build it: If you are on Linux or OS X, you first need to build libusb 1.0A, ie:: cd libusb1 sh autogen.sh make cp libusb/libusb-1.0A.a . cd .. (The libraries are pre-built for MSWin) To build the standalone instrument lib, you need to edit the Makefile to #include the appropriate Makefile.XXX for your operating system, and then run your "make".
