Debugging
Compile-time configuration
There are two compile-time configuration options that assist in debugging
Berkeley DB and Berkeley DB applications.
--enable-debug
If you want to build Berkeley DB with -g as the C and C++ compiler
flag, enter --enable-debug as an argument to configure. This will create
Berkeley DB with debugging symbols, as well as load various Berkeley DB routines
that can be called directly from a debugger to display database page
content, cursor queues and so forth. (Note that the -O
optimization flag will still be specified. To compile with only the
-g, explicitly set the CFLAGS environment variable
before configuring.)
--enable-diagnostic
If you want to build Berkeley DB with debugging run-time sanity checks and with
DIAGNOSTIC #defined during compilation, enter --enable-diagnostic as an
argument to configure. This will cause a number of special checks to be
performed when Berkeley DB is running. This flag should not be defined when
configuring to build production binaries, as it degrades performance.
In addition, when compiling Berkeley DB for use in run-time memory consistency
checkers, in particular, programs that look for reads and writes of
uninitialized memory, use --enable-diagnostic as an argument to configure.
This guarantees that Berkeley DB will completely initialize allocated pages
rather than only initializing the minimum necessary amount.
