再执行下面的sh build_decoder_wasm.sh就会有问题，root@DESKTOP-7ME2BST:/home/blue/data/WasmVideoPlayer# sh build_decoder_wasm.sh

C compiler test failed. If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the [email protected] mailing list or IRC #ffmpeg on irc.freenode.net. Rerun configure with logging enabled (do not use --disable-logging), and include the log this produces with your report.

换到ubuntu环境进行编译，前面ffmpeg编译已经通过，后面build_decoder_wasm.sh执行时报错

请指教一下。
我这边已经通过修改参数暂时可以通过编译，修改 build_decoder.sh如下：
emconfigure ./configure --cc="emcc" --cxx="em++" --ar="emar" --ranlib="emranlib" --prefix=$(pwd)/../WasmVideoPlayer/dist --enable-cross-compile --target-os=none \

我也下载了3.3.9 也使用你的命令.提示 emcc is unable to create an executable file.

这是什么情况啊?

你这个跟ffmpeg版本没有关系，你的Emscripten环境ok吗？
