WASM module load failed: unsupported opcode fc 0a

[Zghw2012]

Hello,

I start to use wasm-micro-runtime. However I can not run the sample.
After I install the wasi-sdk and clone wasm-micro-runtime into local machine (Ubuntu 18). I meet the following problem when I execute the ./multi_module under /wasm-micro-runtime/samples/multi-module/build.

• wasm_runtime_full_init
• wasm_runtime_set_module_reader
• bh_read_file_to_buffer ./mC.wasm
• wasm_runtime_load
• bh_read_file_to_buffer ./mB.wasm
• bh_read_file_to_buffer ./mA.wasm
  WASM module load failed: unsupported opcode fc 0a
• release the read file buffer
• wasm_runtime_destroy
• release the read file buffer
• release the read file buffer

Any suggestions to solve it?

Hi @Zghw2012 , fc 0a opcode is for memory.copy operation (see https://pengowray.github.io/wasm-ops/) which is part of bulk memory proposal. This is supported by WAMR but only enabled by default very recently: #1781
You either migrate to the latest WAMR, or explicitly enable bulk memory by adding -DWAMR_BUILD_BULK_MEMORY=1 to your cmake command.

Thank you very much!
