After a deeper look at the code I realised that actually the called LIBUSB1 is a USB-1.0 with some changes. The author call it "USB-1.0A". And this specific code is used at Linux and Windows drivers. And this code dosn't compile at FreeBSD. So I proceed with USB-0.1. The linker flag actually is "-lusb". > In FreeBSD -lusb is a multi-API library, including v0.1, v1.0 and v2.0. Header > files are in /usr/include Thanks, it was helpfull. With some changes at the code I managed to build argyllcms-1.4.0. -- WBR, Boris Samorodov (bsam) FreeBSD Committer, http://www.FreeBSD.org The Power To Serve
