Problem With C++ Wrapper For Integers

[Jim Leary]

The GMP home page now has under "Status of the current release"
the statement

"gmpxx.h needs the #include <strstream.h> uncommented."
Even with that fix, there still seems to be a basic
problem with this software.

The trivial program

#include "gmpxx.h"

int main (void)
{
        return 0;
}

compiles correctly but if one more statement is added
compiler error happen. The extra line is the declaration
of a gpm type of multiple precision integer


#include "gmpxx.h"

int main (void)
{
        mpz_class a;
        return 0;
}

The reported compiler errors follow:

bash$ g++ test_gmpxx.cpp
/tmp/ccdbudnP.o: In function `__gmp_expr<__gmpz_value,
__gmpz_value>::~__gmp_expr(void)':

+0xe): undefined reference to `__gmpz_init_set_si'
collect2: ld returned 1 exit status


The specs on my compiler and system are in my first bug report
about the need for uncommenting #include <strstream.h>. I
believe my system specs are irrelevent
