Debian Jessie Emscripten installation notes
wget https://s3.amazonaws.com/mozilla-games/emscripten/releases/emsdk-portable.tar.gz tar xvzf emsdk-portable.tar.gz sudo apt-get update sudo apt-get install build-essential cmake python2.7 nodejs default-jre git-core ./emsdk_portable/emsdk update ./emsdk_portable/emsdk install latest # wait a long time. ./emsdk_portable/emsdk activate latest source emsdk_portable/emsdk_env.sh
Edit ~/.emscripten change the line reading:
NODE_JS = 'node'
to
NODE_JS = 'nodejs'
Then create a simple hello word program in hi.c e.g.
#include<stdio.h>
int main() {
printf("hello, world!\n");
return 0;
}
compile with with emscripten as follows:
emcc hi.c -o hello.html
Which will produce hello.html You can then open this with firefox! Emscripten will add a bunch of support code, around this automatically. If you ommit the -o it will produce a a.out.js with the Javascript only.
In addition to the above you might want to add something like the following to your .bashrc, so that the past persist across bash sessions:
PATH=$PATH:/home/new/ems/emsdk_portable PATH=$PATH:/home/new/ems/emsdk_portable/clang/fastcomp/build_master_64/bin PATH=$PATH:/home/new/ems/emsdk_portable/emscripten/master EMSCRIPTEN=/home/new/ems/emsdk_portable/emscripten/master
