I t was never my intention to port the program from c to c++ for the purpose of improving the program. It was solely a learning experience and as such it served its purpose very well. I learned how to apply C99 standards and after some struggling I even managed to use the proper formatting tools in C++. The program itself is rather useless and can now be discarded. C++ is not the preferred programming language for most Linux aficionados. They prefere standard C instead. The kernel does not have a single part written in C++. However, there is a lot of potential in C++, and anyone interested to write programs for his/hers use will find it very useful and powerful. To reap the full benefit it is necessary to get familiar with its syntax and structure. Extra complexity is introduced for portability reason. If you should not care for portability you can make things a lot simpler. e.g use the simple types like int, char, float etc instead of the C99 types. But as always, it is good to know the later forms, so that you can at least read programs written by other people. John -- The Toronto Linux Users Group.

I ended up having to enable UNIX98_PTYS (Device Drivers -> Character devices -> Unix98 PTY support) and DEVPTS_FS (File Systems -> Pseudo filesystems -> /dev/pts file system for Unix98 PTYs) Thanks for your help.

In addition to the cumulative wisdom that comes out of that meeting, I'd like to suggest that anyone with relevant facts and ideas express them now to whoever is most likely to be affected by your particular arguments. I have sent a somewhat techie summary of my point of view to Ana Bassios, Acting Executive Director, Information and Technology.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Have you compiled support for the /dev/pts filesystem into the kernel? (Device Drivers -> File Systems -> Pseudo File Systems -> /dev/pts) I had this problem when I was trying out DevFS, because I disabled /dev/pts Otherwise, check system logs (/var/log/message) and dmesg right after trying to open a terminal. Also, if you start X with "startx", check the console for errors.

Howdy folks, I just installed the 2.6.0 kernel on my sony vaio laptop and I've run into a small problem. I can't get a terminal to run in X. When I start xterm, the window manager draws the window but the shell prompt doesn't show up. This works fine if I reboot with 2.4.23. In 2.6.0, I can login normally on the console and get shell prompt there. I'm assuming that I haven't configured something correctly but I'm a bit stumped as to what. Does anybody have any ideas? Note to other sony vaio owners, the 2.6.0 kernel will not boot with the PnPBios driver enabled. I believe this is because the vaio line of laptops have buggy BIOS's.

No, but it can't be smaller. If it's substantially bigger and you're able to recover successfully, you can resize the file system (e.g. using resize2fs) to take advantage of the additional space. -- tim writer <tim-s/rLXaiAEBtBDgjK7y7TUQ at public.gmane.org> starnix inc. 905.771.0017 ext. 225 thornhill, ontario, canada http://www.starnix.com professional linux services & products -- The Toronto Linux Users Group.

For maximum portability, format to a buffer using sprintf() and print the buffer. By now, you should be convinced that porting the original program from C to C++ yielded no benefits whatsoever at the cost of additional complexity, portability problems, and clumsiness.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 You should use: # dd if=/dev/hda5 of=/dev/hdxx bs=512 conv=noerror,sync where xx is the drive and partition (of same size) That should copy the data exactly, and the "noerror" option will ignore physically corrupt areas (if any). You should first create the new partition with /sbin/fdisk or /sbin/parted. Here is one of the origional helpful documents I used when I had to recover data: <http://www.unixwiz.net/techtips/recovering-ext2.html> Most of the article is about recovering the partition table, which you probably don't need to do (what does "/sbin/fdisk -l" say?), but the beginning is interesting. If I ever find the other articles I've used (kick myself for forgetting to bookmark, I'll post the links. ps. I don't know how to fix your tape drive problems.
