I'm having a constant error in my DLL regarding one simple function: I get the error:
double *(double)' differs in levels of indirection from 'double (double)'
The declaration is:
extern EXP32 double *FAR PASCAL_CONV utc2tdb(double jd);
What can be the problem?

What is the correct syntax if a gcc compiler is to be used?

I'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!?
I'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 ?
have several linux header files included and when I compile my program I get the below errors..Am I NOT supposed to use some of these headers? Source is below as well.Looking through the headers mentioned in these errors, it's looking like stuff really is defined in multiple places...

I want to use two separate files in 1 program, but cannot get it to work. I don't know if it's my files or the compiling thats wrong. I have never used 2 files in my programs so far. Only used #include <stdio.h>.

extern_static.c Code: extern int i;
int main(void)

I have a FTP server, client program and thus I can easily transfer files, however what I want is to modify the program such that server receives a c/c++ file, compiles the output, and sends a text file back to the client containing the output. The program should also take note that errors are also transferred.

I am trying to compile two programs using the same header file and definitions. makefile part to make this work.
================================
My headerfile looks like this:
#ifdef ONE
void hello(int s);
#else
[Code]....
How can I include the flag -DONE in my makefile so that
it includes void hello(int s); for "one" and
int pin;
int verification(char* name);
for "two"
In 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.
I'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?

I'm working on my program that takes input of the employees' first and last name, their payrate, their deferred from check and also the amount of hours they have worked which then the gross is calculated and also the taxes are calculated by an external function. In the program design it is necessary to put arrays which I have done, but when i compile I receive warning messages
Code: warning: format '%s' expects argument of type 'char*', but argument 3 has type 'double'
Warning: format '%f' expects a matching 'double' argument [-Wformat] which I believe is causing my program to just give me garbage when I run it. What do those warnings mean?
Code:
/* Name: Arturo
Date: 03/22/13
Purpose: To learn

extern void calculate taxes(float gross,float deferred, float *ft, float *st, float ........i);

I've recently downloaded the original DOOM source code from id Software's GitHub page. I decided it would be fun to port it to Windows 7. I created a new Win32 application within Microsoft Visual Studio 2010 Professional, added all the DOOM files to the project, and hit compile. I got a ton of odd errors, so I switched the project from C++ to C and hit compile again. I got a few more errors, which I've mostly resolved (they come from the fact that the DOOM code I downloaded was written for Linux in 1993), and an error on nearly every symbol in cmath. The errors are C2059 and C2061. A little bit of digging around online revealed that these errors come from including cmath in a C project. However, I can find no reference to cmath in my code files.
A little more digging around online revealed that certain C++ files, like fstream, include cmath. I removed all of those that I could, but to no avail. How I can get rid of these errors?

Problem: When I add a new variable to complete my program, it crashes. I have tried tracing where the problem is but it leads to adding new variables
Purpose of program: Every 2 lines of the input file belong to 1 participant. The line with decimals include times a person has run miles. While the second line of each participant are integers that indicate the best sets from workouts the participant had done.
so an example of the output
Participant #1
Cardio Workouts:
Best Time:
Worst Time:
Average Time:
Weight Workouts:
Most Sets:
Least Sets:
Average Sets:
Participant #2
...
Why my program is crashing
#include <stdio.h>
int main () {
// Stats Col0=BestTime Col1=WorstTime col2=mostSets col3=leastSets Col4=Average_time Col5=Average_sets
float chart[20][12], stats[10][6], best_time=100, worst_time=0, most_sets=0, least_sets=100, avg_time, avg_sets, sum;

I've written a simple program that output's my name, course, and a time date stamp.
Having researched the code to do so, I've used the includes for both the ctime and time.h libraries.
I leveraged localtime_s and asctime_s to actually convert to string etc., and the program runs fine when I step through it in Visual Studio.
However, we're working with CGI and this program will ultimately be called up from the cgi-bin directory of a web server. The first thing that needs to be done after copying it to the webserver is to compile it. That's where my problem occurs.
Using the console command: g++ lab5a.cpp -o lab5a.exe the file is supposed to compile and be converted to a .exe.
However, instead I receive errors:
localtime_s was not declared in this scope
asctime_s was not declared in this scope
I "believe" it's because of the included libraries, but not sure.
They are:
HTML Code:
#include <iostream>
#include <ctime>
#include <time.h>
Here's the actual timestamp block of code:
HTML Code:
//Begin date and time instructions
time_t curTime;
struct tm locTime;
const int TimeStrLen = 26;
[Code] ....
Of course, I go on to error check and complete the block, but you get the picture.
