Use gdb. We could probably point you to your problem but you need to learn how to use gdb.
the commands you need are:
Quote:
break main <- stop right when the program starts.
step <- enter this repeatedly until you get a segfault.
print [varname] to view contents of a variable
help <- gives you more things to use to navigate
help [command] gives specific help.
compile & debug with
Have fun.

i just started learning arrays and found this example on the net:
for (( i = 0 ; i < ${#names} ; i++ ))

Not sure if this is possible, but I've tried this about a thousand ways now. I am making something with a lot of arrays. I thought I could put the array names into a separate array and then loop through them to call all of their elements. This is the best I've got so far:

I hate I'm asking for help again. Unfortunately it seems there just aren't any links I can find on making an array that holds a bunch of two dimensional arrays. Maybe my google-fu is lacking. Basically I have a header file like this:

int white_l2;

Corona688 was great in helping me learn how to create arrays that hold other two dimensional array here. Unfortunately I didn't think ask about how to implement or call them. Basically, I'm trying to call an array of two-dimensional arrays like this:

gzexe
GZEXE(1) General Commands Manual GZEXE(1)NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
penalty in performance). For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are
sure that /usr/bin/gdb works properly.
This utility is most useful on systems with very small disks.
OPTIONS -d Decompress the given executables instead of compressing them.
SEE ALSO gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the
PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases,
using chmod or chown.
