Thanx, here are my first results:
I tried to compile bison on my Windows machine. Windows is my primary
development platform and I use MinGW. I tried it with gcc 2.95.3 and
gcc 3.1 (beta), but I haven't got it working. Even the
configure-script reported some errors and the compilation required
functions like "pipe" and "fork" not available in my c-lib.
So I went to Linux. Configuration, compilation (gcc 3.1) and
installation did work very well. But the use of this bison made
problems. Not only that I had to add a very large number of
semicolons, one in every rule (was this really necessary? - my grammar
has more than 3000 lines), I got the following in output file:
<<<<<<< bison.simple
while (yyn = yypact[yystate] + YYTERROR,
! (yyn != YYFLAG + YYTERROR
&& 0 <= yyn && yyn <= YYLAST && yycheck[yyn] == YYTERROR
&& 0 < yytable[yyn]))
{
/* Pop the parsing stack. */
if (yyssp == yyss)
YYABORT;
yyvsp--;
yystate = *--yyssp;
=======
for (;;)
{
yyn = yypact[yystate];
if (yyn != YYFLAG)
{
yyn += YYTERROR;
if (0 <= yyn && yyn <= YYLAST && yycheck[yyn] == YYTERROR)
{
yyn = yytable[yyn];
if (0 < yyn)
break;
}
}
/* Pop the current state because it cannot handle the error token. */
if (yyssp == yyss)
YYABORT;
yyvsp--;
yystate = *--yyssp;
>>>>>>> 1.27
This is neither C nor C++. So I could not compile a bison output file
until now.
Finally I must say, the use of m4 is not a good idea in my opinion. So
bison depends on the presence of another tool. Think about the many
Windows developers. The all need m4 now!
