  • 0

I have been strugglling to build posqlgresql 9.1 with trace_locks on so I can check the memory addresses used by the locks, but after a couple of days effort, I still haven’t made any progress.

to compile:

./configure --prefix=/usr/local/pgsql --enable-depend --enable-cassert --enable-debug
make
make install

According to postgresql documentation, LOCK_DEBUG should be set at compile time, 

./configure --prefix=/usr/local/pgsql --enable-depend --enable-cassert --enable-debug LOCK_DEBUG='on'

but it doesn’t seem like working.
Please help! Thanks!!!

    I think you just want to get -DLOCK_DEBUG into the compiler flags, try it like this:

    ./configure \
    --prefix=/usr/local/pgsql \
    --enable-depend --enable-cassert \
    --enable-debug \
    CPPFLAGS='-DLOCK_DEBUG'

    I added the backslashes to make it easier to read, you can use this if you want it all in one line:

    ./configure --prefix=/usr/local/pgsql --enable-depend --enable-cassert --enable-debug CPPFLAGS='-DLOCK_DEBUG'

    You can find examples of similar things in the installation documentation, just search for “CFLAGS”:

    You can specify environment variables on the configure command line, for example: 

    ./configure CC=/opt/bin/gcc CFLAGS='-O2 -pipe'
