[Pkg-javascript-devel] Bug#1135146: emscripten: emcc: error: babel was not found!

[Frank Heckenbach]

Package: emscripten
Version: 3.1.69+dfsg-3
Severity: normal

I don't know much about emscripten. I was just trying to build the
web version of sgt-puzzles. This worked under bookworm.

The message tells me to report a bug, so that's what I'm doing.

If I need to install some package (which? There are many packages
with "babel" in their name) or need to do something differently,
please let me know (or better, include it in the message).

Here's how to reproduce:

mkdir emscripten-test
cd emscripten-test
apt-get source sgt-puzzles/forky
cd */.
emcmake cmake .
cmake  --build .

[...]
