make fails about bison HOT 9 CLOSED

Here is what my machine spits:

bison$ grep _debug src/scan-gram.c
#ifdef yyget_debug
#define gram_get_debug_ALREADY_DEFINED
#define yyget_debug gram_get_debug
#ifdef yyset_debug
#define gram_set_debug_ALREADY_DEFINED
#define yyset_debug gram_set_debug
#ifndef yy_flex_debug
#define yy_flex_debug yyflexdebug
int yyget_debug ( void );
void yyset_debug ( int debug_flag  );
int yyget_debug  (void) {
void yyset_debug (int  _bdebug ) {
  gram__flex_debug = trace_flag & trace_scan;
  gram_debug = trace_flag & trace_parse;

the flex version is identical i.e.,
flex 2.6.4

from bison.

Hi,
Could you please provide details? For instance, how did you run configure? What compiler are you using?
Thanks in advance.

from bison.

Thank you for responding.
compiler:
gcc-12.0.2
Steps:

1. All Prerequisites are satisfied
2. Optional valgrind is installed
3. RAN in the unpacked directory:

~bison$ git submodule update --init
~bison$ ./bootstrap
~bison$ ./configure
~bison$ make

from bison.

Thanks. But now that I have a closer look, it rather looks like the output of flex is not the usual one. It looks like they changed the way they rename their variables.

Could you please run this grep?

$ grep _debug src/scan-gram.c
#define yy_flex_debug gram__flex_debug
#ifdef yyget_debug
#define gram_get_debug_ALREADY_DEFINED
#define yyget_debug gram_get_debug
#ifdef yyset_debug
#define gram_set_debug_ALREADY_DEFINED
#define yyset_debug gram_set_debug
#ifdef yy_flex_debug
#define gram__flex_debug_ALREADY_DEFINED
#define yy_flex_debug gram__flex_debug
extern int yy_flex_debug;
int yy_flex_debug = 1;
int yyget_debug ( void );
void yyset_debug ( int debug_flag  );
                if ( yy_flex_debug )
int yyget_debug  (void)
        return yy_flex_debug;
void yyset_debug (int  _bdebug )
        yy_flex_debug = _bdebug ;
  gram__flex_debug = trace_flag & trace_scan;
  gram_debug = trace_flag & trace_parse;

I'm using

$ flex --version
flex 2.6.4

from bison.

So your Flex behaves as if there was not

%option prefix="gram_"

In the source file src/scan-gram.l...

That file was not edited, wasn't it?

Could you please try this and report the logs?

$ grep gram_ src/scan-gram.l
$ touch src/scan-gram.l
$ make V=1

Thanks!

from bison.

Thank you. Changing the order of installation of flex and bison resolved the problem.

Thank you. Changing the order of installation of flex and bison resolved the problem.

How changing installation order of flex resolve that? I have the same issue.

For the version of the flex: flex --version

flex 2.6.4

output of the grep _debug src/scan-gram.c

Output of grep gram_ src/scan-gram.l :

  gram_debug = trace_flag & trace_parse;
  gram_in = xfopen (gram, "r");
gram_scanner_close (void)
  xfclose (gram_in);
gram_scanner_free (void)

I have src/scan-gram.l file, why should I recreate another one by touch src/scan-gram.l?

And finally for the make V=1
