Hi ALL I am a student of IIT Dellhi. I am working on a project to build usb webcam driver and ex2 filesystem driver for L4. I have compiled loaders downloaded from svn repository on 5th April 1:00 AM IST ,svn revision 444. I am using following gcc version 4.3.2 and ubuntu 8.10 linux. root@tapas-laptop:/home/tapas/tudos/l4# gcc --version gcc (Ubuntu 4.3.2-1ubuntu12) 4.3.2 Copyright (C) 2008 Free Software Foundation, Inc.

This seems to me that some files are not available or deleted from svn . Please correct these two errors. And also let us know correct solution as soon as possible. Please also let us know how can we get stable versions of dice ,fiasco ,hello ,l4env, dope, linux-26-headers, dde_linux26 ,l4ide, ore. Please also let us know menu.lst file for dope with l4env,hello, loader, dde_linux26,l4ide,ore . This seems to me a bug .. Please solve as soon as possible. We need the loader and other modules for our work as soon as possible. We have a plan to build usb webcam and ex2 filesystem driver as soon as possible.
