Where I should write C code (thread moved)

1.5) I also downloaded the MinGW Runtime thingy's. Don't know if they are nessesary, but they won't hurt.

2) I made a folder called GNU and installed MinGW in c:\GNU\MinGW

2.5) I extracted the new runtime stuff and just overwrote what has there

3) I installed MSYS in c:\GNU\msys

Now you get an icon on the desktop where you can start the MinSys. Do this, because is creates your home folder. Then exit it again.

4) Download gmp and place it in your newly created home folder. (For me is was called C:\GNU\msys\1.0\home\Jes )

5) Start the MinSys up again from the desktop and type

gunzip gmp-4.1.4.tar.gz
tar -xvf gmp-4.1.4.tar
cd gmp-4.1.4
./configure
make install

Then GMP installs (takes about two or three cups of cofee ).

6) Afterwards, download ECM-GMP 6 from http://home.in.tum.de/~kruppa/ecm-6.0.tar.gz and place the file in your home folder.

7) In the "home" directory (type cd ~ RETURN to get there) type
gunzip ecm-6.0.tar.gz
tar -xvf ecm-6.0.tar
cd ecm-6.0
./configure --with-gmp=/usr/local
make

8) Look and behold! 4 executables have appeared, and the one to look out for is ecm.exe

Have fun

Thank you for your Explaining how to install the Library Step-by-Step

Please can Anyone tell me where I should write the C Code.
After I did all the step I have only Msys in the start menu
So I intalled the MinGW Developer Studio, then I wrote the simple C Code
like this :

#include <stdint.h>
#include <stdio.h>
#include <string.h>
#include<C:\GNU\1.0\home\Mahmoud Maqableh\gmp-4.1\gmp.h>
#include<conio.h>

int main()
{
mpf_t r;
mpf_init(r);


printf("\n\t The valuse of Xn = %F",r);

mpf_clear (r);
return 0;
}

When I do the Compile there is no any Error, but if I do Run
I have 2 Errors:
H:\Simple.c:16: undefined reference to `__gmpf_init'
H:\Simple.c:21: undefined reference to `__gmpf_clear'


Can Anyone Help me to eliminate these Errors.

Helllo Everyone

I want to install GMP Library on windows XP, I did that but I have problem
I did the Installation like this :

1) Download the current Mingw http://prdownloads.sf.net/mingw/MinG...1.exe?download

Can Anyone Help me to eliminate these Errors."correct the Linking Error"
OR send to me Step-by-step How I can install GMP-4.2 on Windows XP and
do Run to the previous Code.

Please I need the Help urgent.

Note: My PC CPU is : Intel(R) Celeron CPU 2.4GHzis it compatible with Intel P4???? I think GMP do not work with any CPU!!!!!!!

Posts moved, they don't relate to GMP-ECM 6.0.

You have to link with the GMP library.

If you're using the command-line, try adding -lgmp

Hello,

Please, Can I ask you question????
I am using GMP library, and I want to multiply two big
numbers each one consist of 160-bit. One of these numbers
should be less than 1.
Example :

A=12345678901234567890123456789012345678901234567890.

B=0.12345678901234567890123456789012345678901234567890.

I tried to do the following but I can not successed.

void multip
{
mpf_t A,B;

mpf_init2(A,160);
mpf_init2(B,160);

mpf_set (A,12345678901234567890123456789012345678901234567890);
mpf_set (B,0.12345678901234567890123456789012345678901234567890);

gmp_printf("\n\t The valuse of A n = %Ff ",A);
gmp_printf("\n\t The valuse of A n = %Ff ",B);

mpf_clear (A);
mpf_clear (B);

}

The compile Result:

chaos.c: In function `main':
chaos.c:25: warning: integer constant is too large for this configuration of the compiler - truncated to 64 bits
chaos.c:25: warning: decimal constant is so large that it is unsigned
chaos.c:25: warning: passing arg 2 of `__gmpf_set' makes pointer from integer without a cast
chaos.c:71:3: warning: no newline at end of file

if I want to see the chaos.exe I can not, and told me you
should close theprogram.

Please Can you tell me how to do assignment to those variable,
and how to multipy like this big numbers.

Thanks in Advans

How to multipy Two Big numbers using GMP

Try the GMP manual at http://www.swox.com/gmp/manual/, especially the "Basics: What every GMP user should know" section.

You can't use literals that big. Use the functions that accept strings.

[ValerieVonck]

FWIW, in Java you can use the BigInteger Class (java.lang.math.BigInteger)
