make[3]: *** [mysqld.o] Error 1
------------------------------------------------------------------------------
Note the Error, line 1484. The code round here is
------------------------------------------------------------------------------
static void open_log(MYSQL_LOG *log, const char *hostname,
const char *opt_name, const char *extension,
enum_log_type type)
{
char tmp[FN_REFLEN];
...
// get rid of extention if the log is binary to avoid problems
if (type == LOG_BIN)
{
>>>>char* p = strrchr(opt_name, FN_EXTCHAR);
if (p)
*p = 0;
}
log->open(opt_name,type);
}
------------------------------------------------------------------------------
It's trying to modify the buffer pointed to by opt_name, which is
declared as `const'.
>How-To-Repeat:
Try to compile it!
>Fix:
Me, I'd take a copy of opt_name into a local buffer first. In fact you seem
to have one to hand, though you could fall foul of limited buffer size.
A workaround is to remove the `const' from opt_name, but that seems
messy (it's typically poking at command line arguments).
