Install FLINT

[Malay Sarkar]

Hi,
  I have installed FLINT in my Ubuntu machine by the following comment from terminal
sudo apt-get install libflint-dev.

But when I run code by gcc test.c -lgmp  -lflint -lmpfr, I am getting error

test.c:4:19: fatal error: F_mpz.h: No such file or directory
 #include <F_mpz.h>
                   ^
compilation terminated.



My code:

#include<stdio.h>
#include<math.h>
#include<gmp.h>
#include <F_mpz.h>
#include<F_mpz_poly.h>
int main(){
mpz_t a,b;
mpz_init(a);

}

That is a very old version of flint. It is better to build the latest version yourself from source.

Below I will assume your home directory is /home/malay. If not, you will have to change that path below. You may also like to use make -j instead of just make if you have multiple cores.

wget http://mpir.org/mpir-2.7.0-alpha4.tar.bz2

http://www.mpfr.org/mpfr-current/mpfr-3.1.2.tar.bz2

wget http://flintlib.org/flint-2.4.3.tar.gz

tar -xvf mpir-2.7.0-alpha4.tar.bz2

tar -xvf mpfr-3.1.2.tar.bz2

tar -xvf flint-2.4.3.tar.gz

cd mpir-2.7.0

./configure --enable-gmpcompat

make

cd ..

cd mpfr-3.1.2

./configure --with-gmp-build=/home/malay/mpir-2.7.0

make

cd ..

cd flint-2.4.3

./configure --with-mpir=/home/malay/mpir-2.7.0 --with-mpfr=/home/malay/mpfr-3.1.2

make

cd ..

Anyway, to answer your original question, you are missing 

   -I/home/malay/mpir-2.7.0 -I/home/malay/flint-2.4.3 

when running gcc above. It can't find flint.h, fmpz_poly.h or fmpz_mod_poly.h because you didn't tell it where to look. That's what the -I does. (that's I for include by the way, not the letter l). 

You will also need to tell it where to find the libraries by passing 

   -L/home/malay/mpir-2.7.0/.libs -L/home/malay/mpfr-3.1.2/src/.libs -L/home/malay/flint-2.4.3 

to gcc.

You should also have 

#include "flint.h"

#include "fmpz_poly.h" 

#include "fmpz_mod_poly.h"

 

i.e. using double quotes, not angle brackets, since they are not standard library headers.

Bill.

Everything worked perfectly up to when I have to make flint and I get stuck on the following: I have been stuck for 4 days any help will be super appreciated as after this I need Singular4 as well:

THANX GUYS

The latest version of Flint is 2.5.2 (see flintlib.org). I would build that with MPIR 3.0.0 and MPFR 3.1.6 if you have Ubuntu.

We test Flint with Ubuntu all the time. There are no known build issues. Either you have a really old Ubuntu that is broken, or you are doing something incorrect.

If you can't get the latest Flint to build, please tell us exactly what you typed.

Thanks, this looks like a good resource to point people to.
