[U-Boot] [PATCH 12/15] Add support for building native win32 tools

Peter Tyser ptyser at xes-inc.com
Thu Mar 5 00:33:02 CET 2009


Add support for compiling the host tools in the tools directory using
the MinGW toolchain.  This produces executables which can be used on
standard Windows computers without requiring cygwin.

One must specify the MinGW compiler and strip utilities as if they
were the host toolchain in order to build win32 executables, eg:

make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools

+Note: If you wish to generate WIN32 versions of the utilities in
+      the tools directory you can use the MinGW toolchain
+      (http://www.mingw.org).  Set your HOST tools to the MinGW
+      binaries and execute 'make tools'.  For example:
+
+       $ make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools
+
+      Binaries such as tools/mkimage.exe will be created which can
+      be executed on computers using Windows.

 U-Boot is intended to be simple to build. After installing the
 sources you must configure U-Boot for one specific board type. This
 is done by typing:
