Building
--------
-Just type 'make' and 'make install'. If on BSD, for now you have to
-specify the BSD Makefile with -f and use gmake (not make), eg:
+Just type 'make' and 'make install'.
-$ gmake -f Makefile.FreeBSD && gmake -f Makefile.FreeBSD install
-
-Same goes for AIX:
-
-$ gmake -f Makefile.aix && gmake -f Makefile.aix install
-
-Likewise with OpenSolaris, use the Makefile.solaris to compile there.
-The OpenSolaris make should work fine. This might change in the
-future if I opt for an autoconf type setup.
+Note that GNU make is required. On BSD it's available from devel/gmake;
+on Solaris it's in the SUNWgmake package. On platforms where GNU make
+isn't the default, type 'gmake' instead of 'make'.
If your compile fails with an error like this:
based distros, it's typically called libaio-devel.
+Windows
+-------
+
+On Windows Cygwin (http://www.cygwin.com) is required with at least
+devel/gcc4 and devel/make installed in order to build fio, and
+admin/cygrunsrv to run it. You can also install devel/git to fetch/update
+the source files. To create an MSI installer package, install WiX 3.6 from
+http://wix.sourceforge.net/releases/ and run dobuild.cmd from the
+os/windows directory.
+
+Before running fio you'll need to have a copy of cygserver running. Run
+"/usr/bin/cygserver-config" from an elevated Cygwin shell (i.e. launch the
+Cygwin shell under the Administrator account) to configure it. Once
+configured, run "net start cygserver" to start it, or type
+"/usr/sbin/cygserver &" in the Cygwin shell to start a local copy.
+
+If fio exits with the message "Bad system call" it normally means that
+Cygserver isn't running.
