1010 The Makefiles in the OpenJDK are only valid when used with the GNU version of
1011 the utility command `make` (usually called `gmake` on Solaris). A few notes
1012 about using GNU make:
1013 
1014  * You need GNU make version 3.81 or newer. On Windows 4.0 or newer is
1015    recommended. If the GNU make utility on your systems is not of a suitable
1016    version, see "[Building GNU make](#buildgmake)".
1017  * Place the location of the GNU make binary in the `PATH`.
1018  * **Solaris:** Do NOT use `/usr/bin/make` on Solaris. If your Solaris system
1019    has the software from the Solaris Developer Companion CD installed, you
1020    should try and use `gmake` which will be located in either the `/usr/bin`,
1021    `/opt/sfw/bin` or `/usr/sfw/bin` directory.
1022  * **Windows:** Make sure you start your build inside a bash shell.
1023  * **Mac OS X:** The XCode "command line tools" must be installed on your Mac.

1031 ### Building GNU make
1032 
1033 First step is to get the GNU make 3.81 or newer source from
1034 [ftp.gnu.org/pub/gnu/make/](http://ftp.gnu.org/pub/gnu/make/). Building is a
1035 little different depending on the OS but is basically done with:
1036 
1037       bash ./configure
1038       make
