To be able to debug a MySQL client with the integrated debug package, you should configure MySQL with --with-debug or --with-debug=full. See Section 2.3.3.
Before running a client, you should set the MYSQL_DEBUG environment variable:
shell> MYSQL_DEBUG=d:t:O,/tmp/client.trace shell> export MYSQL_DEBUG
This causes clients to generate a trace file in /tmp/client.trace.
If you have problems with your own client code, you should attempt to connect to the server and run your query using a client that is known to work. Do this by running mysql in debugging mode (assuming you have compiled MySQL with debugging on):
shell> mysql --debug=d:t:O,/tmp/client.trace
This will provide useful information in case you mail a bug report. See Section 1.6.2.3.
If your client crashes at some “legal” looking code, you should check
that your mysql.h include file matches your mysql library file.
A very common mistake is to use an old mysql.h file from an old
MySQL installation with the new MySQL library.
