V8Js on MacOS

Installation of V8Js on MacOS is pretty much straight forward.

First of all you need a pretty fresh installation of v8 library. If you have brew around, just brew install v8 and you should be done. Otherwise you need to compile latest v8 manually.

Compile latest v8

cd /tmp

# Install depot_tools first (needed for source checkout)
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=`pwd`/depot_tools:"$PATH"

# Download v8
fetch v8
cd v8

# (optional) If you'd like to build a certain version:
git checkout 3.32.6
gclient sync

# Build
make native library=shared -j8

# Install to /usr
mkdir -p /usr/local/lib /usr/local/include
cp out/native/lib*.dylib /usr/local/lib/
cp out/native/libv8_*.a  /usr/local/lib/
cp -R include/* /usr/local/include

You cannot install the libraries to any location you want since they have a install name that is baked into the library. You can check the install name with otool -D out/native/libv8.dylib.

During the build snapshot generation may fail like so:

ACTION tools_gyp_v8_gyp_v8_snapshot_target_run_mksnapshot /Users/vagrant/v8/out/native/obj.target/v8_snapshot/geni/snapshot.cc
dyld: Library not loaded: /usr/local/lib/libicui18n.dylib
  Referenced from: /Users/vagrant/v8/out/native/mksnapshot
  Reason: image not found
/bin/sh: line 1: 18964 Trace/BPT trap: 5       "/Users/vagrant/v8/out/native/mksnapshot" --log-snapshot-positions --logfile "/Users/vagrant/v8/out/native/obj.target/v8_snapshot/geni/snapshot.log" --random-seed 314159265 "/Users/vagrant/v8/out/native/obj.target/v8_snapshot/geni/snapshot.cc"
make[1]: *** [/Users/vagrant/v8/out/native/obj.target/v8_snapshot/geni/snapshot.cc] Error 133
make: *** [native] Error 2

... if that happens, just copy libicu*.dylib to /usr/local/lib already and start make again (then simply continue with installation):

cp out/native/libicu*.dylib /usr/local/lib/
make native library=shared -j8

Compile php-v8js itself

If you're using Apple LLVM compiler (instead of gcc) you need to pass the -Wno-c++11-narrowing flag. Otherwise compilation fails due to narrowing errors in PHP itself, which LLVM is much pickier with (compared to gcc).

cd /tmp
git clone https://github.com/preillyme/v8js.git
cd v8js
phpize
./configure CXXFLAGS="-Wno-c++11-narrowing"
make
make test
make install
