I'm having a little trouble running a program I made with mysql++1.7.8, when
I run the app it segment faults when the connect object is created.
this is what I am running
Red Hat Linux release 7.0 (Guinness)
Kernel 2.2.16-22 on an i586
Mysql 3.23.32
mysql++1.7.8
gcc 2.96.2
here is how I compile the app
g++ temp.cpp -I/usr/local/mysql/include/mysql -L/usr/local/mysql/lib/mysql
-lsqlplus -Wl,--rpath=/usr/local/mysql/lib/mysql
here is the code
#include <sqlplus.hh>
#include <iostream.h>
int main()
{
cout <<" startup" << endl;
Connection con("temp","localhost","root","temp",3306,0,60,1,"",0);
cout << "done" << endl;
return 0;
}
here is the output
startup
Segmentation fault (core dumped)
here is what causes it to crash
Starting program: /home/projects/code/isv/join/a.out
startup
Program received signal SIGSEGV, Segmentation fault.

now back traceing it

any help to remedy this problem would be great.
