#
#
# 1. INTRODUCTION
#
# This shell script pulls Emscripten from GitHub and uses it to build
# the MPS.
#
# Supported platforms: ?.
#
#
# 1.1. PREREQUISITES
#
# clang, curl, git, nodejs
#
# "python" needs to be Python 2 (otherwise configure fails), so you
# may need to run:
#
# port select --set python python27
#
# You need to have a program "python2" on your path (which runs Python
# 2.7.3), so on OS X with MacPorts you need to run:
#
# ln -s /opt/local/bin/python2.7 /opt/local/bin/python2
# 2. CONFIGURATION
# Emscripten git repository
EMSCRIPTEN_REMOTE=https://github.com/kripken/emscripten.git
# Fastcomp git repository
FASTCOMP_REMOTE=https://github.com/kripken/emscripten-fastcomp.git
# Fastcomp clang git repository
CLANG_REMOTE=https://github.com/kripken/emscripten-fastcomp-clang
# Directory to put everything in
TESTDIR="$PWD/.test"
mkdir -p -- "$TESTDIR" &&
cd -- "$TESTDIR" ||
exit 1
# 3. UTILITIES
# 3.1. checkout REPO REMOTE -- clone a git repository and pull
checkout () {
REPO=$1
REMOTE=$2
if [ -d "$REPO" ]; then
echo "$REPO exists: skipping clone."
else
echo "cloning $REMOTE into $REPO."
git clone --recursive -- "$REMOTE" "$REPO"
fi
(
cd -- "$REPO" &&
git pull
)
}
# 4. PROCEDURE
checkout emscripten "$EMSCRIPTEN_REMOTE"
# See [FASTCOMP].
checkout emscripten-fastcomp "$FASTCOMP_REMOTE"
(
cd emscripten-fastcomp &&
(
cd tools &&
checkout clang "$CLANG_REMOTE";
)
mkdir -p build
(
cd build &&
../configure --enable-optimized --disable-assertions --enable-targets=host,js &&
make;
)
)
