ARM: Using STL vectors

Stephen Eng

Hi,

I'm writing a C++ program that will run on an STM3210E-EVAL board and I'm having some problems using STL vectors. I'm wondering what I'm doing wrong. (Or if STL vectors are even supported.)

Here's a snippet:

#include <vector>

.
.
.

void func()
{
  std::vector<int> temp;

  temp.push_back(5);
}

When I try to run the debugger on my target, I end up somewhere in assembly land and never reach the beginning of my main() function. (I am not familiar with assembly so, I'm not quite sure where I am or how I got there.)

When I run in simulator mode, everything works fine. (I end up at the beginning of my main() function like I expect.)

It appears that whenever I make any command that increases the size of my vector, I get the same result. If I never insert into my vector or resize it, then the debugger brings me to the beginning of main(), like I'd expect.

The last time I saw something like this was when my heap was 0 and I tried newing something on the heap. If anyone has any ideas, I'd be grateful.

I'm required to write my program in C++ and though I'm not required to use vectors, I really would like to. (I also have a few ideas of how to implement it differently if it turns out that vectors don't work.)

Thanks,

Parents

    Using STL will bring in a lot of extra code. C++ can give a smaller program growth when you add one more feature to an existing program. But it tends to produce very large "hello world" applications compared to C programs. And huge "hello world" applications compared to assembler applications.

    It does not sound good that your program does not include your main().
