From 16b2cd579e17d46bdf7bcec3059a92d2c80d21e8 Mon Sep 17 00:00:00 2001 From: konablend Date: Tue, 14 Apr 2009 20:10:57 +0000 Subject: This patch adds mingw32 cross-compilation support to HandBrake trunk to produce native win32 binaries. The main benefits are the binary does not have any Cygwin runtime requirements and various host platforms can be leveraged to build HandBrake. Cross-compilation toolchains are complex to setup and recommended for experts only; but once setup it can build at speeds similar to native builds, on Darwin or Linux. BUILD INSTRUCTIONS: Add mingw32 toolchain to beginning of your path and take the toolchain prefix from gcc (eg: i386-mingw32-gcc) and pass to configure: ./configure --cross=i386-ming32 PRODUCTS: - hb.lib (static library) - HandBrakeCLI.exe DOWNLOADS: Contrib downloads need to be seeded with: - pthreads-w32-2-8-0-release.tar.gz (new) - xvidcore-20090311.tar.gz SUMMARY: Specifically, all GUI trees are not impacted. configure - added --cross=PREFIX - reworked search for gcc and cross-compile related tools to use prefix contrib/ - sub-patches added as needed for mingw contrib/xvidcore/ - bumped from 1.1.3 -> 1.2.1+ (daily 20090311) - reconstituted P01-cygwin.patch - created new P00-darwin.patch needed for macho64 asm flag on x86_64 arch libhb/ - uint -> uint32_t - remaining changes guarded by mingw32 macro. test/ - modified to support pthread-compatibility library attach/detach. - all changes guarded by mingw32 macro.
