To be able to debug a MySQL client with the integrated debug
package, you should configure MySQL with
Section 2.9.7, “MySQL Source-Configuration Options”.
Before running a client, you should set the
MYSQL_DEBUG environment variable:
$> MYSQL_DEBUG=d:t:O,/tmp/client.trace $> export MYSQL_DEBUG
This causes clients to generate a trace file in
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 that you have compiled MySQL with debugging on):
$> mysql --debug=d:t:O,/tmp/client.trace
This provides useful information in case you mail a bug report. See Section 1.6, “How to Report Bugs or Problems”.
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 new MySQL library.
