Emscripten errors on installing

[MongoCaleb]

Following the readme, I did brew install emscripten. When it was complete, I tried the make xwsolve.js and receive the following:

third_party/glucose-3.0/simp  master ✔                                                                                                                   156d

This is probably because it's using a clang++ version already on your system.

I had to change the LLVM path in ~/.emscripten to:
LLVM_ROOT = os.path.expanduser(os.getenv('LLVM', '/usr/local/Cellar/emscripten/1.38.22/libexec/llvm/bin/')) # directory

The homebrew install fails to compile make xwsolve.js for me for lack of Asyncify support:

Compiling: /Users/sam/developer/phil/third_party/glucose-3.0/simp/Main.o
shared:ERROR: ASYNCIFY has been removed from fastcomp. There is a new implementation which can be used in the upstream wasm backend.

The upstream Emscripten build also fails to compile with:

Fatal: local.get of unknown in arg0 of call to $emscripten_asm_const_int (used by EM_ASM* macros) in function $main.
This might be caused by aggressive compiler transformations. Consider using EM_JS instead.

I had your second error (and I'm not on a mac), but fixed it by installing an older version of Emscripten (sdk-1.37.20-64bit, the most recent version at this project's last commit). Building from the source I did

$ ./emsdk install sdk-1.37.20-64bit
$ ./emsdk activate sdk-1.37.20-64bit
$ source ./emsdk_env.sh

That worked well, thanks @lothan

./emsdk install sdk-1.37.20-64bit

This version no longer seems to be available. Attempted to make xwsolve.js but fails on the following versions I tried: latest, 1.39.1, and releases-upstream-048cf9424790cc525a7ea6da340820aae226f3b9-64bit.

Running into this same error. Find any fixes, @dalanmiller ?

[FaritaTasnim]

I'm also running into this same error as @lothan but any SDK previous to 1.39.1 is not installable for me. I tried the sdk's @dalanmiller mentioned but getting the same erros he posted. Anyone have any idea how to move forward?
