Dev C, math.h problems

Question

I just installed devcpp, and am attempting to make sure it is working. When I ran into compile errors surrounding math.h. I am using a couple of simple programs that have been compiled and run before, so there shouldn't be any problems there. I would normally use cmath instead, but I need to use Magick++ for a few things as well, which uses math.h. Has anybody run into this? Know of a work around?

The errors are

Line 594 of math.h expected ')' before '(' token

Line 594 of math.h expected ',' or ';' before '(' token

'abs' undeclared

line 594

 extern double __cdecl nearbyint (double);

and in context

/* 7.12.9.2 Double in C89 */
extern float __cdecl floorf (float);
extern long double __cdecl floorl (long double);

/* 7.12.9.3 */
extern double __cdecl nearbyint (double);
extern float __cdecl nearbyintf (float);
extern long double __cdecl nearbyintl (long double);

where did you download devc++ from? is it the latest version?orwell devc++ or bloodshed devc++? — Koushik Shetty, May 02 '13 at 15:10
I have tried both bloodshed v. 4.9.9.2, and orwell v. 5.4.1. The result is the same with each. — user2207973, May 03 '13 at 15:43
I have tried code blocks as well with the same result. Everything that requires math.h results in an error. — user2207973, May 03 '13 at 20:07
ok then post the code where it gives error. it might not be IDE problem. — Koushik Shetty, May 04 '13 at 03:38
even something as simple as this gives an error `#include #include int main() { int n, result; printf("Enter an integer to calculate it's absolute value\n"); scanf("%d", &n); result = abs(n); printf("Absolute value of %d = %d\n", n, result); return 0; }` sorry about the formatting. — user2207973, May 04 '13 at 17:18

Does this help at all - http://www.cplusplus.com/forum/general/5207/

I'm also using Dev C++ right now and can't stand it, but it is required for a class. Is there a reason you can't just use Visual Studio Express, it is also a free download -

I can't use Visual Studio Express. Imagemagick requires a build, and VSE doesn't have the required libraries to build it. – user2207973 May 03 '13 at 15:48
