[Anonymous]

I am getting the error message

"bison: m4: Invalid argument" when i try to generate
parser file. i ma kinda stuck here, do not know whats the
problem is i searched all existing bugs no mention about
this

unzipped to a folder and updated the path for bison bin
folder

1) What are the version number and the date of the binaries
bison.exe and m4.exe?
2) What is the command line that fails?

I can't reproduce this problem. Can you upload (see 'Check to
Upload ...' below) a small .y file that results in this error?

Also, does the error occur when you don't give the whole
path to bison on the command line (for this to work, bison
and m4 must be in a directory that's in your Path)?

Even after loging in with my sourceforge id i did not see any
update button or link, i am pasting my test grammer here
below.

/ begingin of test.l file /

%{

include <stdio.h>

include <stdlib.h>

int mylineno = 0;
%}

%%
. { printf ("Token: %s\n", yytext); }

%%

int yywrap ()
{
return 1;
}

void yyerror (char* str)
{
fprintf (stderr, "%s", str);
}

/ end of test.l file /

/ begining of test.y file /
%{

include <stdio.h>

include <stdlib.h>

extern int yylex ();
extern int yywrap ();
extern void yyerror (char*);

%}

%token LEX_TOKEN

%start token

%%

token : LEX_TOKEN { printf ("token parsed\n"); }

%%

extern yyparse ();

int main ()
{
yyparse ();
}

/ end of test.y file /

command line to generate scanner and parser code.

bison -d -otest_y.c test.y <--- m4 invalid argument error

if i copy m4.exe to local folder and execute the above
command it generates without any problem

Most likely then, you have another m4 in your path
environment variable before the gnuwin32 one that
accompanies bison. Check this carefully. If direct inspection
does not yield any result, then use the command 'which -a
m4' (http://gnuwin32.sourceforge.net/packages/which.htm).
