-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

+build fio. To create an MSI installer package install WiX 3.7 from
+http://wixtoolset.org 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. 
+How to compile FIO on 64-bit Windows:

 
 

-If fio exits with the message "Bad system call" it normally means that
-Cygserver isn't running.
+ 1. Install Cygwin (http://www.cygwin.com/setup.exe). Install 'make' and all
+    packages starting with 'mingw64-i686' and 'mingw64-x86_64'.
+ 2. Download ftp://sourceware.org/pub/pthreads-win32/prebuilt-dll-2-9-1-release/dll/x64/pthreadGC2.dll
+    and copy to the fio source directory.
+ 3. Open the Cygwin Terminal.
+ 4. Go to the fio directory (source files).
+ 5. Run 'make clean'.
+ 6. Run 'make'.
