With wasi-sdk toolchain [1], now you can
./configure --cc=${wasi-sdk}/bin/clang \
--cxx=${wasi-sdk}/bin/clang++ \
--ar=${wasi-sdk}/bin/ar \
--strip=${wasi-sdk}/bin/strip \
--nm=${wasi-sdk}/bin/llvm-nm \
--ranlib=${wasi-sdk}/bin/ranlib \
--extra-cflags="--target=wasm32-wasi -D_WASI_EMULATED_SIGNAL
-D_WASI_EMULATED_PROCESS_CLOCKS"
--extra-libs="-lwasi-emulated-signal -lwasi-emulated-process-clocks"
--disable-inline-asm \
--disable-x86asm \
--disable-network \
--disable-protocol=fd \
--disable-protocol=pipe \
--enable-cross-compile \
After make, you can run examples directly on cmdline with wasi runtime,
for example, wasmtime [2] and wasmer [3]
wasmtime --dir . ./demux_decode ./bbb.mp4 bbb-v bbb-a
wasmer --dir . ./demux_decode ./bbb.mp4 bbb-v bbb-a
Besides trying out wasm, I don't know what else it can be used for.
