Others should read the install -instructions in the manual, gmp.info. Use "info -f gmp.info", or, if you -don't have info, use type "C-h i g (gmp.info)Top" in emacs. - -Here are short instructions how to install MP, and some examples that help you -get started using MP. - -First, you need to compile, and optionally install, MP. Since you're -impatient, try this: - - ./configure; make - -If that fails, or you care about the performance of MP, you need to read the -full instructions in the chapter "Installing MP", in the manual. - -Next, you need to try some small test programs, for example the ones below. - -In MP programs, all variables need to be initialized before they are assigned, -and cleared out before program flow leaves the scope in which it was declared. -Here is an example of a program that reads two numbers from the command line, -multiplies them, and prints the result to stdout. - - #include <stdio.h> - #include <gmp.h> /* All MP programs need to include gmp.h */ - - main (int argc, char **argv) - { - mpz_t a, b, p; - - /* Initialize variables */ - mpz_init (a); - mpz_init (b); - mpz_init (p); - - /* Assign a and b from base 10 strings in argv */ - mpz_set_str (a, argv[1], 10); - mpz_set_str (b, argv[2], 10); - - /* 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); - - /* Clear out variables */ - mpz_clear (a); - mpz_clear (b); - mpz_clear (p); - exit (0); - } - - -In practice, that example would be written like this instead: - - #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); - } - -Finally, you have to compile your test program, and link it with the MP -library. Assuming your working directory is still the gmp source directory, -type: - - gcc -g -I. example.c libgmp.a - - -Now try to run the example: - - a.out 98365871231256752134 319378318340103345227 - 31415926535897932384618573336104570964418 - -The functions used here all operate on the domain of signed integers. -Functions operating on that domain have names starting with "mpz_". There are -many more such functions than used in these examples. See the chapter -"Integer Functions" in the manual, for a complete list. - -There are two other main classes of functions in MP. They operate on rational -numbers and floating-point numbers, respectively. The chapters "Rational -Number Functions", and "Floating-point Functions" documents these classes. - -To run a set of tests, do "make check". This will take a while. - -To create the printable documentation from the texinfo source, type "make -dvi". This requires the "tex" command to be available in your search path. - -To install the library, do "make install". - -If you decide to use MP, It is a good idea you read at least the chapter "MP -Basics" in the manual. - - -Known Build Problems --------------------- - -Note that GCC 2.7.2 (as well as 2.6.3) for the RS/6000 and PowerPC can not -be used to compile GMP, due to a bug in GCC. If you want to use GCC, you -need to apply the patch at the end of this file, or use a later version of -the compiler. - -If you are on a Sequent Symmetry, use GAS instead of the system's assembler -due to the latter's serious bugs. - -The system compiler on NeXT is a massacred and old gcc, even if the -compiler calls itself cc. This compiler cannot be used to build GMP. You -need to get a real gcc, and install that before you compile GMP. (NeXT -might have fixed this in newer releases of their system.) - -Please report other problems to bug-gmp@prep.ai.mit.edu. - - -Patch to apply to GCC 2.6.3 and 2.7.2: - -*** config/rs6000/rs6000.md Sun Feb 11 08:22:11 1996 ---- config/rs6000/rs6000.md.new Sun Feb 18 03:33:37 1996 -*************** -*** 920,926 **** - (set (match_operand:SI 0 "gpc_reg_operand" "=r") - (not:SI (match_dup 1)))] - "" -!
