VS2010编译VP8 – 欧几理得

在编译VP8的过程中遇到点问题，Windows编译个东西累死个人。

* /cyddrive/c/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin

*./vcvars32.bat amd64

源码使用这里的：http://code.google.com/p/webm/downloads/list

msys比较简单，可以按http://www.webmproject.org/code/build-prerequisites/这里的来，也直接使用svn检出这个，或者访问下载：

http://src.chromium.org/svn/trunk/deps/third_party/mingw

下载这个文件：mingw-get-inst-20101030.exe

安装的时候

在Repository Catalogues时选择：Download lastest repository catalogues

在Select Components时选择：C++ Compiler/MSYS Basic System之类

C:\MinGW\msys\1.0\msys.bat可以创建一个桌面快捷方式

C:\MinGW\msys\1.0\etc中的fstab中可以加入用户可以访问的文件系统。比如你的源代码在D:

可以增加

D:\ /src

记得yasm要在Microsoft VC目录中，比如C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin，这个路径也要加到PATH环境变量里。

配置64位vs10环境，不过脚本最高支持到vs9

./configure –target= x86_64-win64-vs9

$ ./configure --target=x86_64-win64-vs9

在VS的vpx项目设置中yasm的包含路径我去掉了.才好用***。这个问题值得注意。
可以参考的信息：
./configure参数

Usage: configure [options]
Options:

Build options:
--help                      print this message
--log=yes|no|FILE           file configure log is written to [config.err]
--target=TARGET             target platform tuple [generic-gnu]
--cpu=CPU                   optimize for a specific cpu rather than a family
--extra-cflags=ECFLAGS      add ECFLAGS to CFLAGS []
--enable-extra-warnings     emit harmless warnings (always non-fatal)
--enable-werror             treat warnings as errors, if possible
(not available with all compilers)
--disable-optimizations     turn on/off compiler optimization flags
--enable-pic                turn on/off Position Independent Code
--enable-ccache             turn on/off compiler cache
--enable-debug              enable/disable debug mode
--enable-gprof              enable/disable gprof profiling instrumentation
--enable-gcov               enable/disable gcov coverage instrumentation

Install options:
--enable-install-docs       control whether docs are installed
--disable-install-bins      control whether binaries are installed
--disable-install-libs      control whether libraries are installed
--enable-install-srcs       control whether sources are installed

Advanced options:
--disable-libs                  don't build libraries
--disable-examples              don't build examples
--libc=PATH                     path to alternate libc
--as={yasm|nasm|auto}           use specified assembler [auto, yasm preferred]
--disable-fast-unaligned        don't use unaligned accesses, even when
supported by hardware [auto]
--enable-codec-srcs             in/exclude codec library source code
--enable-debug-libs             in/exclude debug version of libraries
--disable-md5                   support for output of checksum data
--enable-static-msvcrt          use static MSVCRT (VS builds only)
--enable-vp8                    VP8 codec support
--enable-internal-stats         output of encoder internal stats for debug, if supported (encoders)
--enable-mem-tracker            track memory usage
--enable-postproc               postprocessing
--disable-multithread           multithreaded encoding and decoding.
--disable-spatial-resampling    spatial sampling (scaling) support
--enable-realtime-only          enable this option while building for real-time encoding
--enable-error-concealment      enable this option to get a decoder which is able to conceal losses
--enable-runtime-cpu-detect     runtime cpu detection
--enable-shared                 shared library support
--disable-static                static library support
--enable-small                  favor smaller size over speed
--enable-postproc-visualizer    macro block / block level visualizers

Codecs:
Codecs can be selectively enabled or disabled individually, or by family:
--disable-<codec>
is equivalent to:
--disable-<codec>-encoder
--disable-<codec>-decoder

Codecs available in this distribution:
vp8:    encoder    decoder

NOTES:
Object files are built at the place where configure is launched.

All boolean options can be negated. The default value is the opposite
of that shown above. If the option --disable-foo is listed, then
the default value for foo is enabled.

终于搞定了。需要将vpx项目中yasm的include设置，从.;..\src直接修改成一个路径，可以是绝对路径或者直接使用..\src。.不需要特别指出。
