windows-7 - Windows 7 x32 で libvpx をビルドできない

Question

libvpx を code.google.com からダウンロードします Qt4.8 で libvpx を使用したいです。私が続いたhttp://www.webmproject.org/code/build-prerequisites/ しかし毎回失敗しました。cygwin で ./configure を実行すると、次のようになります。

Configuring selected codecs
  enabling vp8_encoder
  enabling vp8_decoder
Configuring for target 'x86-win32-gcc'
  enabling x86
  enabling runtime_cpu_detect
  enabling mmx
  enabling sse
  enabling sse2
  enabling sse3
  enabling ssse3
  enabling sse4_1
  using yasm
  enabling postproc
Unable to invoke compiler: gcc  -fno-common -m32

Configuration failed. This could reflect a misconfiguration of your
toolchains, improper options selected, or another problem. If you
don't see any useful error messages above, the next step is to look
at the configure error log file (config.err) to determine what
configure was trying to do when it died.

そしてconfig.errで：

# ./configure 
Configuring selected codecs
  enabling vp8_encoder
  enabling vp8_decoder
