Emscripten compiling error: STACK_SIZE unknown

[craigsapp]

I am getting this error when running buildToolkit in the emscripten directory:

Linking...
em++: error: Attempt to set a non-existent setting: 'STACK_SIZE'
 - did you mean one of ASYNCIFY_STACK_SIZE?
 - perhaps a typo in emcc's  -sX=Y  notation?
 - (see src/settings.js for valid values)
 Failed.

STACK_SIZE is used in buildToolkit (and has since its beginning). I have not updated emscripten since it was previously working. Do you know why ASYNCIFY_STACK_SIZE is needed and STACK_SIZE is unknown?

Here is the cmake configuration that the script uses:

configure: cmake ../cmake -DBUILD_AS_WASM=ON "\
   -DCMAKE_CXX_FLAGS=-O3 -DNDEBUG -std=c++17 \
   -s STRICT=1" \
   -DCMAKE_TOOLCHAIN_FILE=/Users/craig/git-cloud/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake -DCMAKE_CROSSCOMPILING_EMULATOR=/Users/craig/git-cloud/emsdk/node/14.18.2_64bit/bin/node;--experimental-wasm-threads

And the emcc version I am using (on MacOS):

emcc --version
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.24 (68a9f990429e0bcfb63b1cde68bad792554350a5)
Copyright (C) 2014 the Emscripten authors (see AUTHORS.txt)

Using note 14.18.2_64bit with emcc 3.1.24.

You need to update emscripten. It is something that has changed recently. It was TOTAL_SIZE before.

Thanks! That worked. emcc is now version 3.1.28 and it is using the same node version 14.8.2_64bit.

After the update there were six more compiler warnings than before. Previously, only the first one below was reported:

Great. The new compiler warnings are related to the deprecation of codedvt in c++17
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0618r0.html
The problem is that there is currently not standard alternative to it.
