FAQ

0. Are pevious exam sheets w/wo sample solutions available?

Yes. For example, sample solutions for exam 02/12/96. In general, Omega Staencilkomitte prints an updated collection before each exam period.

1. "X Error of failed request: BadAlloc..." when running xshow. Why?

I know the problem, it comes up in signy-salen on the Silicon Graphics machines. I suspect there is something about the X server on the SG's but I have no solution. Xshow runs well on Suns (idi), Ultrix (lise) and Linux (in my home) machines.

If somebody comes around the problem please let me know.

2. Why do I get errors when sourcing the scripts xite_cshrc and xite_login?

These scripts were written for tcsh, while at stud the default shell is bash. To solve the problem, either get your login shell changed to tcsh, or if you prefer keeping bash, just run tcsh before sourcing the scripts and starting xshow (or other xite progs).

If somebody was willing to rewrite the scripts for bash, contact me (not so much work).

3. Why do I get 'Unknown user:' error when trying to source xite_cshrc or xite_login?

On stud and the idi systems xite is located in different places. If you work at stud (signy, lise), you find xite at ~adm45032/xite. On the idi system it is located at ~bilde/xite.

3. How to compile an program which used XITE library under UNIX/Linux?

You have to use cxite instead of gcc or CC. Why, because this program makes all the link automatically for you. You do not need to include the libray when make create the executable.

3. Why the compiler cannot find the include file when I am compiling under UNIX/Linux?

It can happen that the include are not referenced in the general path of the compiler. So, the simplest way to resolve this problem is to create a link in your home directory or the directory you have your working files. This link should be named cxite and it should link the include directory of XITE (usually they are in $XITE_HOME/include).

The command is like this:
ln -s $XITE_HOME/include xite

when you compile your program you should now include this line at the command line:
cxite prog1... -I./xite
(this example supposes that the link xite is in the current directory, you can put it elswhere, but put the right path after the -I)
