can't find source file error

[nmn]

Hi,
Can you tell me what I should be looking for when this error occurred:
"Can't find a source file at "malloc.c"
Locate the file or edit the source lookup path to include its location."

The occurred when this call arrayPtr = new int[indexSize]; this call is done multiple times before w/in main w/o error. Then it pops up on the last call !

Can you give us all you code

[nmn]

thanks in advance...

I brought couple of changes to your program It works fine even I dont have your csis.txt

I think your progblem is in testx functions because you call a member function of IntArray class in wrong way

use a.wait(); instead of wait();

void test1()
{
    IntArray a(10);
    for(int i = a.low(); i <= a.high(); i++)
    {
        a[i] = i * 10;
    }
    a.setName('a');
    cout << a << endl;
    a.wait();
}

Please use code tags next time

hope that help

sorry, I should have included the wait(), it's actually part of the iadrv.cpp file, not part of the IntArray.cpp.

But here is an error I've found running the program with gdb.

Program received signal SIGSEGV, Segmentation fault.
0xb7d8d175 in malloc_consolidate (av=0xb7ebc440) at malloc.c:4257
4257 malloc.c: No such file or directory.

my question is what file or directory is it looking for ?

[28poGNh0]

The compiler show this error

No such file or directory.

when we include a header that does not exists and unknow by the compiler
for exp if you write # include "malloc.c" or # include <malloc.c>

that's what I think ,On what IDE do you program?

[nmn]

I wrote it on Eclipse Indigo (ubuntu)...but I ran the gdb via Xterm.

[28poGNh0]

I never worked on Eclipse Indigo I use currently VS c++ and code::blocks I am sorry I cant give you something I dont know

can you me a link to download this compiler?

[nmn]

go to eclipse.com you can download it there.
I think I am closing in on this @#$@ :) I ran valgrind to track down memory usage and I got the same error every time testx is called...
