C :: Error When Compiling WHILE Statement

/* Demonstrates using the gets() return value. */
#include <stdio.h>
/* Declare a character array to hold input, and a pointer. */
char input[257], *ptr;

I just got this from the book that I am using and it is for testing for input of a blank line and readers are being warned in using this format (line 18):
Code: while ( (*ptr = gets(input)) != NULL)
What is the correct syntax if a gcc compiler is to be used?

C :: Error Including Undeclared Structure
Aug 11, 2013I get this error :
stra.c:54:29: error: "PS_index" undeclared (first use in this function)
and the function is
PS_Index = function(PS_index, indexData);
so what i am trying to do is :
first file:
Code:
#include <stdio.h>
#include <stdlib.h>
#include "stra.h"
int main (){
char name[] = "index.pif";
uint32_t i = 0;
[Code] .....
And header file:
Code:
typedef struct StraIndex{
uint32_t s;
uint32_t *i;
uint32_t *t;
}StraIndex; s
So first I would like to create my stra.o so i compile it as :
gcc -c stra.c -o stra.o
and then i get the above error. What would be the proper way to get a global structure inside my object.

C++ :: Xcode 4 Not Compiling?
Mar 20, 2012I'm taking an intro to c++ class and during an exercise I ran into multiple errors that are out of my knowledge to fix. The rest of the class is using Visual and that is all the instructor knows so i'm in my own figuring out Xcode. Basically I wrote the same program twice but one has a different struct and I get all sorts of errors with it. understand what the errors are and why they occurred.
The working program is this:
#include <iostream>
#include <fstream>
#include <iomanip>
#include <cmath>
using namespace std;
struct point {
public:
double x1,y1;
double x2,y2;
[code]....
This program does not compile and I get the following errors:
stl_iterator_base_types.h
1) Symantic Issue
No type named 'value_type' in 'myPoint'
2) Symantic Issue
No type named 'iterator_category in 'myPoint'
3) Symantic Issue
No type named 'difference_type' in 'myPoint'
4) Symantic Issue
No type named 'pointer' in 'myPoint'
5) Symantic Issue
No type named 'reference' in 'myPoint'
Why does one work and the other doesn't!?
Visual C++ :: Compiling On X86 CPU?
Apr 30, 2015I'm compiling some open source code (originally written for Linux / gcc) which uses the following line to determine if a particular section is being compiled for an x86 processor:-
Code:
#if ( defined(__x86_64__) || defined(__i386__) )
neither of those seems to be defined by my ageing compiler (VC++ 8.0). What would be the equivalent for building with VC8 ?

C++ :: Ignore Code When Compiling?
Sep 7, 2012In a rather large codebase, there is a set of recurring calls to a couple vararg functions (mainly for logging)
Code: logthis(foo, bar(), somefunction(parameter1,parameter2), somethingelse);
The number of parameters to this function is variable It has all types of variables, function calls, etc.
The code has thousands of these lines
There is now a need for a special version of the compile that will remove a lot of the code, among others is the logging.
Can I somehow #define the "logthis" name into something that'll remove all actual calls to the code. including the actual parameters/expressions to the call.
I can't afford to add #ifdef/#endif around each of the calls because there are too many of them, and because that'll cause some undisired side effects in our code conformance tests.
Code: #define logthis __noop
comes close, that removes the call, but it still causes the compiler to evaluate and validate all the parameters to the logthis function, which doesn't work because in this case, removing the logging headers also removes other members of the class that get used as part of the parameters to logthis()
if I could define logthis into // resulting in all the rest of the line being comments, but that doesn't work.
Preferably I'd like something to be portable, but I'll take a solution that only works on visual studio as well.
C :: Best Process For Cross Compiling Application
Oct 26, 2013I'm creating a small command line game in C. I have never done anything cross platforms, but this is small enough (so far) that it might not be too bad.
When I am done, I'm not sure how it will be distributed: Either I will just send people the C files and say "compile on your system with these options", or I will just have executables for various systems. Probably Windows 7/8, Ubuntu, CentOS, and whatever I can find to test on.
I right now I'm testing/developing on Windows 7 using MinGW. So my questions are: while I'm developing, how should I be compiling/testing it?
