32-bit emcc fails to work in Linux

[mcandre]

Hi, I am able to build 64-bit WASM artifacts with emcc in Debian Buster. However, when I install and activate the 32-bit edition, then emcc fails:

$ . /emsdk/emsdk_env.sh && emcc -s WASM=1 -o bin/hello.wasm hello.c
Adding directories to PATH:
PATH += /emsdk
PATH += /emsdk/clang/fastcomp/build_incoming_32/bin
PATH += /emsdk/node/8.9.1_32bit/bin
PATH += /emsdk/emscripten/incoming
PATH += /emsdk/binaryen/master_32bit_binaryen/bin

Setting environment variables:
EMSDK = /emsdk
EM_CONFIG = /root/.emscripten
LLVM_ROOT = /emsdk/clang/fastcomp/build_incoming_32/bin
EMSDK_NODE = /emsdk/node/8.9.1_32bit/bin/node
EMSCRIPTEN = /emsdk/emscripten/incoming
EMSCRIPTEN_NATIVE_OPTIMIZER = /emsdk/emscripten/incoming_32bit_optimizer/optimizer
BINARYEN_ROOT = /emsdk/binaryen/master_32bit_binaryen

emscripten:INFO: generating system asset: is_vanilla.txt... (this will be cached in "/root/.emscripten_cache/is_vanilla.txt" for subsequent builds)

I don't thikn the emsdk provides 32-bit builds anymore - we just have one linux builder, which is 64-bit.

If you built fastcomp yourself, then it could work. In that case maybe something's wrong with that node build - you can just edit the .emscripten file to point it to the system node.js (node LTS or later would work).

You can also do what the error message suggests, to run that command manually (after Expected the command in that output), and see if there's an error message.
