Hi, I have trouble trying to deal with a client in india who only has a xeon
processor or a dual core and my application uses MySQL++ library to make the
connection to mysql. The MySQL installation is a regular rpm file nothing
specific for the 64 bit and i can run it just fine, but when my application
runs on the xeon / dual core it core dumps at the time when i am trying to
connect to mysql, connect() throws an exception, unfortunately the
executable i sent to client didnt have a catch in it, so i dont know what
seems to be the exact reason, but someone ever face this issue?

I can run the exact same code here in my lab with a regular P4.

What gives?

Thanks
Ankur

password and enter with mysql -u user -p option??

Anything?

Dear Ankur

Yes, i think you will need to rebuild, because amd64 and Intel noncona
(known as x86_64) are a different binary platform if the os and or the code
was compiled with any optimization like the -march=someprocessor flag, but
the weird thing seems to happen with your executable, you should try
recompiling it for x86_64.

Myself I own one of those Sempron processors with a Venice Core, so it is
x86_64, and i use ubuntu, sometimes code compiled for normal 32 bit
processor does not work as desired because of the little different binary
compatibility between the code.

Actually you can specify them in the mysqlpp::Connection constructor, look:

Connection<http://tangentsoft.net/mysql++/doc/refman/html/classmysqlpp_1_1Connection.html#a1>(const
char *db, const char *host="", const char *user="", const char
*passwd="", uint<http://tangentsoft.net/mysql++/doc/refman/html/namespacemysqlpp.html#a7>port=0,
my_bool compress=0, unsigned int connect_timeout=60,
cchar<http://tangentsoft.net/mysql++/doc/refman/html/namespacemysqlpp.html#a6>*socket_name=0,
unsigned int client_flag=0)

Thanks for the response, I am doing that...

I have the following information in my user table

/*!40000 ALTER TABLE `user` DISABLE KEYS */;
LOCK TABLES `user` WRITE;
INSERT INTO `user` VALUES

and I have the exact same info in my P4 machine and I can log in without a
problem, when i run my command i get the following error

Access denied for user 'provision'@'Lemko08.localdomain' (using password:
YES)

Anything I could be missing..

Ankur,

Which version of libmysqlclient / libmysqlpp are using in your
application ? Are both statically / dynamically linked ? Also which
MySQL server version is running on the x86_64 host ? I'm thinking that
you might have been using older libmysqlclient (before v.4.1) and trying
to connect to MySQL 4.1/5.0 server.

Regards,
Ovidiu
