Post subject:  Using AMP
Hello.

I'd like to use the AMP library. And I have some troubles.

I use MVSC 2010 Express. To use the AMP I add gmp.h, mpfr.h, ap.h, amp.h header files into the project.
Then I add amp.cpp and ap.cpp. Next I compile ap.cpp. But amp.cpp isn't compiled:

"e:\cprogs\amprf\amp.h(24): fatal error C1083: Cannot open include file: gmp.h: No such file or directory"

You have to add gmp.h into search path of your project... or store in the same directory where you store the rest of the library.

It seems the problem is solved by changing include directories. Because amp.h includes gmp.h like #include <>.
But project doesn't work.

I try to compile following code

Code:
#include "amp.h"
int i=3;
    amp::ampf<128> a(i);
   void main () {
   }


As a result of this:

Quote:

I think it means I make something wrong.

P.S. AlgLib version 3 is more simple to use, but I need the amp.

In the third version of AlgLib LNK2019 problem is solved by including all .cpp files. But in this version there are just ap.cpp and amp.cpp.

Also I didn't use build.bat and I don't know how to use it.

Attempt of including static libraries results in error LNK2005.

You also need MPFR, library which supports arbitrary precision transcendent functions.

If it's msvc-x86-mpfr.lib from "_internal" folder than I add it to the project as "Additional Dependencies". Also I add msvc-x86-gmp.lib.

But :
