Can't build duckdb-wasm from source

[Tishj]

What happens?

The instructions on the README.md are not working.

-- Build files have been written to: duckdb-wasm/build/relsize/eh
+ emmake make -Cduckdb-wasm/build/relsize/eh -j12 duckdb_wasm
make: make -Cduckdb-wasm/build/relsize/eh -j12 duckdb_wasm
make[1]: *** No rule to make target `duckdb_wasm'.  Stop.

The build_loadable: recipe has GEN=ninja, this results in creating a build.ninja file in these folders, not a Makefile

I've fixed this by commenting out export GEN=ninja from my ~/.zshrc and also removing the GEN=ninja from the build_loadable recipe

That results in reaching the next error:

These two issues (GEN=ninja breaking and the Parse method not accepting the iterator returned from .begin()) are fixed by #2024

Summary of remaining issues:

• make apply_patches + make serve are not sufficient to build successfully
• emsdk version should be locked to 3.1.69-3.1.71
• Install instructions for emsdk are missing:

git clone https://github.com/emscripten-core/emsdk.git ~/emsdk
~/emsdk install 3.1.69
~/emsdk activate 3.1.69
echo 'source "~/emsdk/emsdk_env.sh"' >> $HOME/.bash_profile

• Install instructions for yarn are missing: sudo npm install -g yarn
• Install instructions for js-beautify are missing: sudo apt install node-js-beautify (on ubuntu)

What does exist in that directory is:
packages/duckdb-wasm/src/bindings/duckdb-mvp.d.ts
Not
packages/duckdb-wasm/src/bindings/duckdb-mvp.js

Contents of that file:

import { DuckDBModule } from './duckdb_module';
export function DuckDB(moduleOverrides?: Partial<DuckDBModule>): Promise<DuckDBModule>;
export default DuckDB;

EDIT:
Fix was running make wasm_dev
That creates all the bindings that the script is looking for
But that still means that:

make apply_patches
make serve

does not work.

I've tried running this on a linux VM, which resulted in this error:

                    ^

EDIT:
That seemed to be fixed by locking the emscripten version to 3.1.69

needs:

• wabt
• npm
• js-beautify (use node-js-beautify)
• yarn (do not use apt-get install yarn)
• cargo (use rustup)

I've been able to get a build working, my next step was to try to load an out-of-tree extension, this hasn't worked yet.
But that's a separate issue
