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. + + + +---------------- +Local variables: +mode: text +fill-column: 76 +End: -- cgit v1.2.3
