From 2f8d396b9302eddcd8d552648e101a46b7a80acd Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Fri, 13 Mar 2009 18:54:51 -0500 Subject: [PATCH] Add support for building native win32 tools 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 Signed-off-by: Peter Tyser --- README | 10 +++++++ include/image.h | 2 ++ include/libfdt_env.h | 12 ++++++++ tools/Makefile | 23 ++++++++++----- tools/mingw_support.c | 79 +++++++++++++++++++++++++++++++++++++++++++++++++++ tools/mingw_support.h | 51 +++++++++++++++++++++++++++++++++ tools/mkimage.h | 5 ++++ tools/os_support.c | 24 ++++++++++++++++ tools/os_support.h | 29 +++++++++++++++++++ tools/ubsha1.c | 3 ++ 10 files changed, 231 insertions(+), 7 deletions(-) create mode 100644 tools/mingw_support.c create mode 100644 tools/mingw_support.h create mode 100644 tools/os_support.c create mode 100644 tools/os_support.h diff --git a/README b/README index fcc4d7c..142dbcc 100644 --- a/README +++ b/README @@ -2716,6 +2716,16 @@ necessary.
