I want to build a parser to compile, link, and run in an 8051 microcontroller using Keil's uVision/51. Has anybody out there done this before? Spencer Doidge...
I certainly haven't.. I think that you'll have fun porting C to that platform. What chip is that? Wilbur ... Putting A Human Face On Technology ;-) ... ...
One of the chips is the Cypress EZ-USB. I'm having a problem with the FILE macro. My system's <stdio.h> doesn't define that. I can't override FILE with my own...
Hello all, Is it possible to parse statments from stdin using flex/bison in win32? All the examples you guys have are parsing from files. I have tried this...
It might be the end of line character that isn't hitting.. Wilbur ... Putting A Human Face On Technology ;-) ... Literally! http://www.TheFaceOf.com...
I tried eating the newline char, and I tried sending it to bison as part of the parse(grammar). Both did not work. Do you have any code where you used stdin...
Hi, I have been using flex and bison for some time now, and I've been able to create some rather extensive parsers in a unix environment with gcc. I've been...
But I think on the console it's not newline, but rather carriage return.. not 10 by rather 13 ... Wilbur ... Putting A Human Face On Technology ;-) ... ...
The port that I've done has never had a problem with the files being compiled on linux.. http://www.monmouth.com/~wstreett/lex-yacc/lex-yacc.html I don't...
This is probably an unacceptable solution, but when I develop parsers for C++ builder, I just comment out the call to #include <unistd.h>, and all works fine....

Yu have to comment everytime yu generate cpp files. Instead of doing that, yu can create a dummy unistd.h header file & put it in standard headers directory, ...

Since bison lets you put your own #defines and such at the top of your output .c file, it was easy to port to with my oddball microcontroller. I didn't find a...
In this case it's the Cypress EZ-USB 8051 microcontroller. I don't know what the next one is, because the data sheet isn't here right now. It will be some...

You should be able to .. it was ported in MSVC 5.0 I'll send you the source directly, rather than to the list. Wilbur ... Putting A Human Face On Technology...
You can find on the internet free C cross compilers for 8051 ( and also Basic compilers ). To write a new one may be a difficult task , but surre it is also an...
Hi, I have C grammer files and lex specifications. I have started using flex and bison just a few days ago. I have generated lex.yy.c and parser_tab.c files...
ATUL, Try adding a simple yyerror function in your main file. e.g. yyerror(char *s) { printf("Error %s\n",s); } I'm really surprised you have gone as far as...

Sadly, Wilbur, lex fails for lack of portability. Specifically, the use of FILE and its fields, ties the program to UNIX. Rewriting the code to make i/o more...
