SECOND REQUEST:
After input from the discussion group I have tried the following:
1. Here is my directory structure:
/Users/davidbower/cplusplusCode/gmp-5.1.0
The arbitraryPrecisionArithmetic.cpp code lives in cplusplusCode while the gmpxx.h resides in the subdirectory gmp-5.1.0.
2. The only way I can get rid of the error stating that there is no gmpxx.h file (see below) is to
a. Replace the angle brackets around gmpxx.h with quotes as in #include <gmpxx.h> --> #include "gmpxx.h".b. Switch to the subdirectory gmp-5.1.0 and compile with "g++ -lgmpxx -lgmp ../arbitraryPrecisionArithmetic_1.cpp"
3. I no longer get a "no such file or directory" for gmpxx.h
4. Instead I get the following error: ld: library not found for -lgmpxx
-- This is an extremely frustrating problem. Any help would be appreciated.
Thanks,
David Bower
FIRST REQUEST:
Please help me get the GNU arbitrary precision arithmetic library working. Thanks. -- David Bower

Here is the contents of the report attached to this email:
// file: arbitraryPrecisionArithmetic_1.cpp
#include <iostream>
#include <gmpxx.h>
int main()
{
mpz_class x("7612058254738945");
mpz_class y("9263591128439081");
std::cout << "\n " << x << "\n*\n " << y;
std::cout << "\n---------------\n" << x * y << "\n\n";
}
Description of what is wrong:
I am trying to run the simple program above on a MAC OS X Lion 10.7.4 command line. (This program was copied directly from the wikipedia webpage describing GNU arbitrary precision arithmetic.)
I get the following error when I run the command "gcc -lgmpxx -lgmp arbitraryPrecisionArithmetic_1.cpp" :
arbitraryPrecisionArithmetic_1.cpp:4:19: error: gmpxx.h: No such file or directory
I also tried the command "gcc -lgmpxx -lgmp -I/gmp-5.1.0 arbitraryPrecisionArithmetic_1.cpp" with the same results.
GMP version number: 5.1.0
Test program: See top of this file.
Configuration options:
1. I downloaded the tarred file gmp-5.1.0.tar.bz2 from the GNU arbitrary precision arithmetic website.
2. I unpacked the file with tar -xvf gmp-5.1.0.tar.bz2
3. This produced a directory "gmp-5.1.0".
4. I changed to the directory gmp-5.1.0
5. I ran the command ./configure --disable-shared --enable-static (sometimes preceeded with "sudo")
6. I ran the command "make install"
7. I ran the command "make check". Every test passed with this last command.
Compiler version. When I type gcc -v I get:
