NC is a high level Socket binding for Windows. It derives from a stripped down version of Claw.Sockets, with all Claw (www.rrsoftware.com), and most Windows, specific aspects removed. It's only Windows dependencies are WSAStartup, WSACleanup, and WSAGetLastError, which should be easily replaceable for use under Linux, for instance. A simple example program, GETJPG.ADB, is included. This demo fetches a webcam picture and saves it on disk as pic.jpg To compile and link the demo program Gnat: gnatmake -gnato -O2 getjpg will compile and link. It needs access to libwsock32.a, so if it doesn't find that you'll need to copy it from the Gnat lib directory. Janus: Create a Console mode project (ie, lkc.bat, not lkw.bat) and do a make getjpg You will probably need to add "wsock32.lib" just before the "-map:%1.map" in lkc.bat Note that Janus, with multiple Ada tasks mapped to a single Windows thread, needs to use the nc-sockets-alt_gethostbyname.asm instead of adb to avoid blocking on a DNS lookup. "make" should automatically choose the asm over the adb file. ObjectAda: Create a Console mode project, making sure to include OA\apilib\ in Project/Settings/Search.
