Hi,

I have a libX.a that I've created (from test.c) and put in /usr/lib/

I've then created another libY.a, that calls functions in libX.a, I've also copied this lib to /usr/lib/

Now when I...

Ok, that works, but doesn't solve my next problem:

Hi,

Say I have a directory structure:
lib/dbg/debug.h
lib/other/other.h
lib/other/other.c
tools/program.c

And other.c has: #include "lib/dbg/debug.h"

Hi,

Why can't I do the following:



#include <stdio.h>
#include <stdlib.h>

class A {

But I have passed it a pointer.

Or do you mean doing?:



char log_filename[100];
double *buf = NULL;
int buf_len;

The routine is in another .c file and the calls to it are in a main() routine set. Except the buf variable is a global variable.

And yes the buf is set to NULL first. Sorry forgot to add that in...

Hi guys,

From what I've tried and read I can't use outb() or inb() to control a parallel port (which connects via usb).

Any body know how to control a parallel port for systems without a...

I wish to increase the size of an array inside a function, since I don't know the size of the array before I call the function.

I would think I could do (for example):

Just thought one of you might be able to give me some advise on coding a good real-time camera logger (i.e. save images with timestamps). FYI I'm using OpenCV to grab frames and save images.

I've...

Solved: As I suspected, it was a serial port config issue. I had the strip
parity bit option set (i.e. options.c_iflag |= (INPCK | ISTRIP)).

Hi,

When I send 0xff over serial, I only recv 0x7f. My write/read type is unsigned char, so I can't see why I'm not recv'ing the MSB. Any ideas?

Thank you.

Of course, now complies with:



template<typename T>
class MyArray
{
public:
MyArray();
//MyArray(MyArray& copy);

Ok, so after fixing the code to:



template<typename T>
class MyArray
{
public:
MyArray();
//MyArray(MyArray& copy);

Ok, some fix is:



MyData(MyArray<int>& x, MyArray<int>& y);


should be

For the following code template_eg.cc:



template<typename T>
class MyArray
{
public:
MyArray();
MyArray(MyArray& copy);

Just found that out now. Thx peoplez.

I'm use to using malloc instead.

Nope :( - was not aware of "placement new" until now.

How can a C++ developer use the placement new syntax to make new allocate an object of class SomeClass at a particular memory address stored in a pointer type variable named pmem?

A. new...
