Ubuntu :: Field 'struct' Has Incomplete Type

May 13, 2011

I'm building a symbol table and syntax tree using lex and yacc for a compiler.

I am stuck with an error for too long. I have defined two structures (one for Symbol Table and another for Syntax Tree).

Code:
typedef struct symbolTable{
char name[30];
.....
struct symbolTable *next;

[Code]......

here's the error:

bottomup.y:76: error: field 'info' has incomplete type.

I tried to define the structure definitions in a separate header file and included in .y file but it didn't work out.

I'm trying to get this done ASAP.

Programming :: POSIX__Philosophers At Dinner: Error: Initializer Element Is Not Constant

Jun 23, 2010

I changed my post because I found that solution, and didn't want to bother for that. But, since I didnt find a way to delete the post, I thought of updating it: I am beginning to write the code for the philosophers problem. As you know, they can eat, think or wait for forks. When they have 2 forks, one by each side, they eat. Then they set the 2 forks as available, and think.

Each philosopher is a thread. My problem is that it gives segmentation fault, somehow, when I try to initialize. The thing I really don't understand, is why it sometimes gives segmentation fault on initialization #0!!! (But generally on initialization #1) I have set 5 initializations in total, defined by N, that is also the number of threads I'm working on.

PHP Code: #include<stdio.h>
#include<stdlib.h>
#include<unistd.h>
#include<pthread.h>
#include<errno.h>
#include<time.h>
#defineN5

Programming :: [C++] Error: Array Must Be Initialized With A Brace-enclosed Initializer

Jun 29, 2011

I'm implementing exceptions using longjmp() (since C++ exceptions don't offer the features that I need, including resuming and a "finally" block), like this:

Code:

jmp_buf ex_jmpbuf;
void *ex_exception;
bool ex_resumable;
jmp_buf ex_resumebuf;

[code]....

Why are the curly braces being misinterpreted as arrays here, but not anywhere else?

Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?

Aug 21, 2009

I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.

For example:

Code:

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

Programming :: Make A New Variable With The String From The Old Variable Btut Without Any Plus Sign?

Apr 7, 2010

my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.

i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't

foo=+12.40

Programming :: Using Variable In A Command?

Apr 14, 2011

i'm trying to execute a shell script, i'm trying to use the values in an array for use in a sed command:

sed -n '/Sales ID: ${array[$i]}/,/Totals:/p'

that command creates empty files. so my guess is that its not recognizing the array as an array but as text?
how would i be able to utilize the array in the command? i got it, didnt think that if i doubled up the single quotes that it would work, but this worked:

sed -n '/Sales ID: '${array[$i]'}/,/Totals:/p'
