- DEMONSTRATION CALCULATOR PROGRAM |
- |
- |
-This is a simple program, meant only to show one way to use GMP with yacc |
-and lex to make a calculator. Usage and comments on the implementation can |
-be found in calc.y. |
- |
-Within a GMP build tree, the generated Makefile can be used to build the |
-program, |
- |
- make calc |
- |
-(or on a DOS system, "make calc.exe"). |
- |
-Elsewhere, once GMP has been installed, the program can be compiled with for |
-instance |
- |
- gcc calc.c calclex.c -lgmp -o calc |
- |
-Or if GNU readline is used then |
- |
- gcc calc.c calclex.c calcread.c -lgmp -lreadline -o calc |
- |
-(again, on a DOS system "-o calc.exe"). |
- |
-Readline support can be enabled or disabled in calc-config.h. That file is |
-created by the GMP ./configure based on the --with-readline option. The |
-default is --with-readline=detect, which means to use readline if available. |
-"yes" can be used to force it to be used, or "no" to not use it. |
- |
-The supplied calc.c was generated by GNU bison, but a standard yacc should |
-work too. |
- |
-The supplied calclex.c was generated by GNU flex, but a standard lex should |
-work too. The readline support may or may not work with a standard lex (see |
-comments with input() in calcread.c). Note also that a standard lex will |
-require its library "-ll" on the compile command line. "./configure" sets |
-this up in the GMP build tree Makefile. |
