RE: [Mysqlcppapi-main] where to find libmysqlclient.so for Solaris 2.8 with gcc 3.3

[Liu, Y. <Yig...@an...>]

Hi Jonathan,

Thanks for your reply. It happens during connection setup. I added a
pair of printout statements before and after each line in the code. Here
are what I got:

bash-2.03$ ./simple1
before mysqlcppapi::Connection con;...
after mysqlcppapi::Connection con;...
before con.connect();...
Bus Error (core dumped)
bash-2.03$

And I got the stack trace here:

#0  0xff0422f0 in _free_unlocked () from /usr/lib/libc.so.1
(gdb) bt
#0  0xff0422f0 in _free_unlocked () from /usr/lib/libc.so.1
#1  0xff0422a8 in free () from /usr/lib/libc.so.1
#2  0xff307490 in mysql_close () from
/usr/local/lib/libmysqlclient.so.10
(gdb) q

And exception handling works for my c++ program. I can throw and catch
exceptions.

Thanks a lot for your kind help!

Yigong

It works for me - if the connection is not opened an exception is
thrown and caught by the first catch() block.

Have you debugged the program to see where the crash is?
It could be before the exception is even thrown, or it could be a
problem with exception-handling in your environment.
If you can send a stacktrace I might be able to figure it out.
