所以我创建了 ffmpeg 配置文件，使它成为纯 C （平台独立，但只是理论上）
所以我的配置很简单（0.6.1,0.6.3 测试）：
./configure --disable-doc --disable-ffplay --disable-ffprobe --disable-ffserver --disable-avdevice --disable-avfilter --disable-pthreads --disable-everything --enable-muxer=flv --enable-encoder=flv --enable-encoder=h263 --disable-mmx --disable-shared --prefix=bin/ --disable-protocols --disable-network --disable-optimizations --disable-debug --disable-asm --disable-stripping
在 Linux 上编译它会解析 4 个库，总大小为 1 mb。
但我需要使用自定义编译器编译 ffmpeg（开源 gcc 模拟称为Adobe Alchemy，让我们将 C/c++ 编译成 Flash）
在标准 Make 期间，它几乎在每个文件上都给了我错误：
Array @ARGV missing the @ in argument 1 of shift() at /home/rupert/Downloads/alchemy-ubuntu-v0.5a/achacks/gcc line 218.
cc1: error: unrecognized command line option "-Wtype-limits"
cc1: error: unrecognized command line option "-fno-signed-zeros"
那么我该怎么办 - 如何通过炼金术编译 ffmpeg（至少是它的最小部分）？
更新 如果我们手动修复这些错误（configure.mak 中有 2 个，alchemy gcc 中有 1 个），我们会得到一个非常混乱且冗长的输出，例如：
> $ make -w install
