-lgmp not working, please help.

[Ragbir S. Chana]

I am using cygwin under Win2K,  5.00.2195, Service Pack 4 (just upgraded from SP3 yesterday but no change).

Name of the computer: mecury.

AMD Athlon Processor AT/AT COMPATIABLE.

523,740 KB RAM

 

cygwin was installed recently under the following directory:

c:\cygwin

 

gmp is installed under gmp-4.1.2, as follows:

C:\cygwin\usr\gmp-4.1.2

 

Also the PATHS appear OK to me.

address@hidden ~/programs
$ $PATH
bash: /cygdrive/h/root/bin:/etc:/usr/gmp-4.1.2/.lib:/lib/gcc-lib/i686-pc-cygwin/
3.2/include:/lib/gcc-lib/i686-pc-mingw32:/usr/local/bin:/usr/bin:/bin:/cygdrive/
g/oracle/9iDSHome/jdk/jre/bin/classic:/cygdrive/g/oracle/9iDSHome/jdk/jre/bin:/c
ygdrive/g/oracle/9iDSHome/bin:/cygdrive/g/oracle/9iDSHome/jlib:/cygdrive/g/oracl
e/ora92/bin:/cygdrive/c/Program: No such file or directory

 

address@hidden ~/programs
$

---

 

When I try to link with gmp libraries, I get the following message
address@hidden ~/programs
$ gcc -o test1 test1.c -lgmp
/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../i686-pc-cygwin/bin/ld: cannot fi
nd -lgmp
collect2: ld returned 1 exit status

 

address@hidden ~/programs

The listing of test1.c is as follows:

 

 #include <stdio.h>
    #include <gmp.h>

 

    main (int argc, char **argv)
    {
      mpz_t a, b, p;

 

      /* Initialize and assign a and b from base 10 strings in argv */
      mpz_init_set_str (a, argv[1], 10);
      mpz_init_set_str (b, argv[2], 10);
      /* Initialize p */
      mpz_init (p);

 

      /* Multiply a and b and put the result in p */
      mpz_mul (p, a, b);

 

      /* Print p in base 10 */
      mpz_out_str (stdout, 10, p);
      fputc ('\n', stdout);

 

      /* Since we're about to exit, no need to clear out variables */
      exit (0);
    }

 The feeling I am getting is that cygwin is not even aware that there exists gmp installation. As far gmp installation itself, that appeared to install successfully.

Do you think it was a mistake for me to install gmp at the present location C:\cygwin\usr\gmp-4.1.2

or

do you think I should have installed under C:\cygwin\usr\local\gmp-4.1.2     ????

 

Any help will be greatly greatly appreciated as I have already spent quite some time with this baby. By the way simple hello.c works OK.

 

Thanks
