11) What is configure all about? The files configure and configure.in are part of the GNU autoconf package.
Configureallows us to test for various capabilities of the OS, and to set variables that can then be tested in C
programsand Makefiles. Autoconf is installed on the PostgreSQL main server. To add options to configure, edit
configure.in,and then run autoconf to generate configure. When configure is run by the user, it tests various OS
capabilities, stores those in config.status and config.cache, and modifies a list of *.in files. For example, if there
existsa Makefile.in, configure generates a Makefile that contains substitutions for all @var@ parameters found by
configure. When you need to edit files, make sure you don't waste time modifying files generated by configure. Edit
the*.in file, and re-run configure to recreate the needed file. If you run make distclean from the top-level source
directory,all files derived by configure are removed, so you see only the file contained in the source distribution.
12) How do I add a new port? There are a variety of places that need to be modified to add a new port. First, start
inthe src/template directory. Add an appropriate entry for your OS. Also, use src/config.guess to add your OS to
src/template/.similar.You shouldn't match the OS version exactly. The configure test will look for an exact OS version
number,and if not found, find a match without version number. Edit src/configure.in to add your new OS. (See
configureitem above.) You will need to run autoconf, or patch src/configure too. Then, check src/include/port and
addyour new OS file, with appropriate values. Hopefully, there is already locking code in
src/include/storage/s_lock.hfor your CPU. There is a backend/port directory if you need special files for your OS.
