我正在 64 位 Windows 7 下构建 libvpx（但希望针对 win32 平台构建），按照此处的说明进行操作：
http://www.webmproject.org/code/build-prerequisites/
我正在使用 Mingw 并使用 yasm 1.1.0 执行此操作。
我主要完成了所有流程，这导致为 MSVS 2010 创建了所有项目和解决方案文件。
当我在 MSVS 2010 中打开解决方案时，libvpx 无法构建（所有其他项目都依赖于此），出现以下错误：
Error 1 error MSB3721: The command "yasm -Xvc -f Win32 -I .;..\libvpx-v1.2.0 -o Win32\Release\vpx\dct_mmx.obj -rnasm -pnasm "..\libvpx-v1.2.0\vp8\encoder\x86\dct_mmx.asm"" exited with code 1. D:\libvpx-v1.2.0\build\x86-msvs\yasm.targets 45 6 vpx
在 SO 和其他网站上搜索给了我类似的东西，比如：
http://code.google.com/p/webrtc/issues/detail?id=197
但据我了解，它与 webrtc 有关，并且 OP 可能也在构建 yasm，这与我的情况不同 - 我不是在构建 yasm，而是从其网站下载。
简而言之，以下步骤会在我这边产生这个问题：
- 安装明威
- 确保 MingW/bin 在系统路径中
- 下载yasm（通用可执行文件）
- 复制 yasm-1.1.0-win32.exe 到 MingW/bin 目录
- 将 yasm-1.1.0-win32.exe 重命名为 yasm.exe
- 打开命令提示符，确保我不在 Mingw/bin 目录中，然后输入 yasm
- 它响应： yasm: 没有指定输入文件，所以我确信 yasm.exe 是从其他目录中找到的
- 遵循http://www.webmproject.org/code/build-prerequisites/中的所有步骤
- 直到构建 VS 项目
- 运行制作
- 确保生成所有项目和 .sln 文件
- 在 MSVS 2010 中打开 .sln 文件（需要从 2008 转换到 2010，并且转换过程完美无缺）
- 构建解决方案 - 它失败（但构建 obj_int_extract 给我 obj_int_extract.exe 文件）
- 然后尝试只构建 vpx 项目，给我上面提到的与 yasm 相关的错误
现在，由于我没有构建 yasm，而仅依赖 yasm.exe，所以我不应该收到此错误，对吧？同样出于同样的原因，我真的不在乎 x86insn_gas.gperf 或 x86insn_nasm.gperf 是否存在 - 如果我错了，请纠正我。
有没有人遇到过这个问题，可以更好地指导我吗？
作为参考，make 命令的输出在视图中没有显示什么奇怪的东西，这里是：

Edit2 (20-12-2013)： 好的，根据 Michael 的建议，我尝试使用 cygwin 执行此操作（MingW 可能会处理 ; 不同），但遇到了一些错误：
