.net won't find my math include file

#1

Hi,
Just written a simple plugin but when I go to build, i get the error:

fatal error C1083: Cannot open include file: ‘math’: No such file or directory

the code I have for the includes is (in part):
#include <string>

#include <iostream>

#include <math>

it finds the others ok, and math.h is in what appears to be the correct folder, i’m using the .net version of C++. Any clues, I’m new to plugins.

Could it be because string and iostream are C++ libs and therefore don’t need a “.h” extension, but the maths lib (which is standard C) needs the extension?

Just a guess? :shrug:

#3

it was because I didn’t have

#define REQUIRE_IOSTREAM

on the top line. A new learning curve for me :slight_smile: should be fun tho, I have some cool ideas for stuff to write, its like everything with me, slog slog, then all of a sudden “ding” as the penny drops, all seems clear, and off I skip over the sunset.

Now it complies ok, I just don’t get the output I expect.

if your header file is called “math.h”, then you include directive should be

#include <math[b].h[/b]>

iirc the #define REQUIRE_IOSTREAM just forces vc++ to use the .h versions of your c++ stdlib headers rather than the newer versions with no extensions…

i did try using the .h extension on it, but maybe i was being thick, although this is another useful peice of info thanks for the info m8.

Is there a <cmath> as part of the standard library?

See,

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcstdlib/html/vclrf_cmath_header.asp

“Defines the macros traditionally defined in the Standard C library header <math.h>.”
…
“Including this header also ensures that the names declared with external linkage in the Standard C library header are declared in the std namespace. In this implementation, the names may or may not also be declared in the global namespace, depending on the specific translation environment.”

The header you need is <cmath>. <math.h> is deprecated, like most of the old .h extension header files.

i will try on friday, I’m stuck with no laptop at the moment, so I can’t play :frowning: weep

Thanks for all the help guys.
