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.

Hi All,
I'm trying to get a script to loop through an array. The array is basically a list of .zip files. I'd like the script to loop through and unzip the zip files contained in the zip file list. When I run the script, it unzip the first zip file correctly, and then stops Any thoughts? Here's... (2 Replies)
Hi,
I am trying to assign an array as a value to one of the array element, I mean
I have an array @KS and array @kr.
I want array @KS to hold @kr as an element.
So I am doin this
$KS=@kr;
But the value stored is number of elements in the @kr array.

hi Gurus,
I'm a newbie in scripting please check my script if this is correct. I think there's something wrong with it but I;m not sure. I'm trying to create multiple lines using awk from external xml files but i want to add additonal info in the data manually
Since i don't knwo how to... (0 Replies)
i just started learning arrays and found this example on the net:
for (( i = 0 ; i < ${#names} ; i++ ))
do
echo ${names}
done
However, even though I can echo ${#names}
I am unable to get the increment to work. I have tried eliminating spaces and changing brackets and nothing seems... (4 Replies)
Hi all,
I am trying to loop through the string contents of an array, to add it during the saving of the output files. I am trying this code to print each column and save it to unique file name, but it doesn't work. Thanks for any help.

hello,
i need a bit of help on how to do this effectively in bash without a lot of extra looping or massive switch/case
i have a long array of M elements and a short array of N elements, so M > N always. M is not a multiple of N.
for case 1, I want to stretch N to fit M

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_l1;
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:

int (*side_one) = { { white_l1,... (6 Replies)

vbo_rendering(3) Coin vbo_rendering(3)NAME
vbo_rendering - Vertex array and VBO rendering in Coin Coin 2.5 added improved support for OpenGL vertex array and VBO rendering. This
might lead to major rendering performance improvements compared to the old rendering code. The new rendering code has been added for the
SoIndexedFaceSet, SoVRMLIndexedFaceSet, SoIndexedLineSet, SoVRMLIndexedLineSet, SoPointSet and SoVRMLPointSet nodes.
To take advantage of the improved performance vertex array and VBO rendering yields, you'll need to organize your vertex data in a way that
makes it possible to render it with OpenGL vertex arrays. OpenGL vertex array rendering does not support multiple index arrays, so all your
vertex data (coordinates, normals, colors and texture coordinates) must use the same index array; or use OVERALL binding. For the indexed
nodes, this means that PER_VERTEX_INDEXED and OVERALL are the only supported bindings for materials, normals and texture coordinates. When
PER_VERTEX_INDEXED binding is used, the corresponding index field should by empty. This will signal the shape to use the coordIndex field
for indices. Below is an example scene graph that will be rendered using vertex arrays:
NormalBinding { value PER_VERTEX_INDEXED }
Coordinate3 {
point [
0 0 0, # 0
1 0 0, # 1
2 0 0, # 2
0 1 0, # 3
1 1 0, # 4

2 1 0, # 11
2 1 -1, # 12
2 2 0, # 13
2 2 -1 # 14
]
}
Normal {
vector [
0 0 1, # 0

]
}
IndexedFaceSet {
coordIndex [
0, 1, 4, 3, -1,
1, 2, 5, 4, -1,
3, 4, 7, 6, -1,
4, 5, 8, 7, -1,
9, 10, 12, 11, -1,
11, 12, 14, 13, -1
]
normalIndex [ ] # = use coordIndex
}.fi
Please note that since only one index array can be used, it might be necessary to supply duplicate normals and coordinates to meet this requirement.
Also, if normals are needed, you have to supply them. A shape with autogenerated normals can't be rendered using vertex arrays (since a single coordinate might get multiple normals).
The PointSet nodes can always be rendered using vertex arrays since these nodes haven't got index arrays, and the only bindings supported are PER_VERTEX and OVERALL.
If it's inconvenient to create vertex array ready scene graphs directly from your application, it's also possible to use SoReorganizeAction to reorganize the geometry before rendering.
