This appendix will help you port MySQL to other operationg systems. Do check the list of currently supported operating systems first. See Which OS. If you have created a new port of MySQL, please let us know so that we can list it here and on our web site (`http://www.mysql.com/'), recommending it to other users.

Note: If you create a new port of MySQL, you are free to copy and distribute it under the GPL license, but it does not make you a copyright holder of MySQL.

A working Posix thread library is needed for the server. On Solaris 2.5 we use Sun PThreads (the native thread support in 2.4 and earlier versions are not good enough) and on Linux we use LinuxThreads by Xavier Leroy, <Xavier.Leroy@inria.fr>.

The hard part of porting to a new Unix variant without good native thread support is probably to port MIT-pthreads. See mit-pthreads/README and Programming POSIX Threads (`http://www.humanfactor.com/pthreads/').

The MySQL distribution includes a patched version of Provenzano's Pthreads from MIT (see the MIT Pthreads web page at `http://www.mit.edu:8001/people/proven/pthreads.html'). This can be used for some operating systems that do not have POSIX threads.

It is also possible to use another user level thread package named FSU Pthreads (see FSU Pthreads home page (http://www.informatik.hu-berlin.de/~mueller/pthreads.html)). This implementation is being used for the SCO port.

See the thr_lock.c and thr_alarm.c programs in the mysys directory for some tests/examples of these problems.

Both the server and the client need a working C++ compiler (we use gcc and have tried SPARCworks). Another compiler that is known to work is the Irix cc.

To compile only the client use ./configure --without-server.

There is currently no support for only compiling the server, nor is it likly to be added unless someone has a good reason for it.

If you want/need to change any Makefile or the configure script you must get Automake and Autoconf. We have used the automake-1.2 and autoconf-2.12 distributions.

All steps needed to remake everything from the most basic files.

/bin/rm */.deps/*.P
/bin/rm -f config.cache
aclocal
autoheader
aclocal
automake
autoconf
./configure --with-debug=full --prefix='your installation directory'

# The makefiles generated above need GNU make 3.75 or newer.
# (called gmake below)
gmake clean all install init-db

If you run into problems with a new port, you may have to do some debugging of MySQL! See Debugging server.

Note: before you start debugging mysqld, first get the test programs mysys/thr_alarm and mysys/thr_lock to work. This will ensure that your thread installation has even a remote chance to work!
