emcc not found,

[David Ciro Taborda]

Hello people,

I am trying to install emscripten in my desktop with Ubuntu 20.04.2 LTS. I followed the package documentation in

https://emscripten.org/docs/getting_started/downloads.html

Everything follows as expected, however after I set the environment variables using source ./emsdk_env.sh nothing happens. The compiler emcc is not found by the system and ./emcc --check returns ./emcc: No such file or directory.

I have followed the same procedure in a PopOS laptop without any problem. Do you have any suggestion to identify the problem?

Thanks!

What does `source ./emsdk_env.sh` output? 

What does `which emcc` say after you run that command?

Does the `upstream/emscripten` directory exist within `emsdk`?   Does `upstream/emscripten/emcc` exist?

If this problem persists can you open an issue in the emsdk repo?

cheers,

sam

Thanks for your response:

after running source ./emsdk_env.sh in the emsdk folder I get:

Adding directories to PATH:
PATH += /home/david/WebDev/emsdk
PATH += /home/david/WebDev/emsdk/upstream/emscripten
PATH += /home/david/WebDev/emsdk/node/14.15.5_64bit/bin

Setting environment variables:
PATH = /home/david/WebDev/emsdk:/home/david/WebDev/emsdk/upstream/emscripten:/home/david/WebDev/emsdk/node/14.15.5_64bit/bin:/home/david/gopath:/home/david/gopath/bin:/home/david/anaconda3/bin:/home/david/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
EMSDK = /home/david/WebDev/emsdk
EM_CONFIG = /home/david/WebDev/emsdk/.emscripten
EMSDK_NODE = /home/david/WebDev/emsdk/node/14.15.5_64bit/bin/node

Then, the which emcc command returns the correct location of the binary:

/home/david/WebDev/emsdk/upstream/emscripten/emcc

Also, the `upstream/emscripten` directory exists within `emsdk`   and contains the binary emcc

It appears that the emsdk_env.sh script is not setting the paths globally. I opened a different terminal and the command which emcc replied with an empty line, the installation appears to be OK.

Additionally, there is a typo in https://emscripten.org/docs/building_from_source/verify_emscripten_environment.html#sanity-tests. The command does not require ./

You have pointed me in the right direction. I will figure how to set the environment globally.

Actually the comments in source ./emsdk_env.sh are clear about setting the paths for the current terminal alone. I did not read thoroughly before running the script.

Thanks!
