Hi,
I've built MySQL++ 1.7.9 libs on an smp machine. But every application which
is built using mysql++ crashes with segfault when invoking connect() method.
For example:
#include <iostream>
#include <mysql++>
void main()
{
try
{
Connection con( use_exceptions );
con.connect();
}
catch ( BadQuery er )
{
std::cout << er.error.c_str() << endl;
}
}
Last lines of strace - libc 2.2.5, linux 2.4.18 smp (the same result for
libc 2.2.4, linux 2.4.16 smp).:
..............
open("/etc/mysql/my.cnf", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=1897, ...}) = 0

open("/home/projects/kia2/.my.cnf", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No
such file or directory)

On another server (libc 2.2.4, linux 2.4.3, MySQL++ 1.7.9) the same place:
open("/etc/mysql/my.cnf", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or
directory)
open("/var/lib/mysql/my.cnf", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such
file or directory)
open("/home/baubas/.my.cnf", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file
or directory)
socket(PF_UNIX, SOCK_STREAM, 0) = 3
fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR)
connect(3, {sin_family=AF_UNIX, path="/var/run/mysqld/mysqld.sock"}, 110)
= -1 ENOENT (No such file or directory)
shutdown(3, 2 /* send and receive */) = 0
close(3) = 0
brk(0x8058000) = 0x8058000
brk(0x805a000) = 0x805a000
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 2), ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= 0x40016000
write(1, "Can\'t connect to local M"..., 93) = 93
munmap(0x40016000, 4096) = 0
_exit(0) = ?
I don't get where is the problem, because it crashes only on the second
server. Any help would be appreciated.
Thanks in advance :)
