V8Js on GNU/Linux
=================
Installation of V8Js on GNU/Linux is pretty much straight forward.
The biggest hurdle actually is that you need a rather new v8 library.
However most distributions still ship the rusty version 3.14, publish
years ago, since Node.js requires such an old version.
This means that you usually need to compile v8 on your own before
you can start to compile & install v8js itself.
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
sudo mkdir -p /usr/lib /usr/include
sudo cp out/native/lib.target/lib*.so /usr/lib/
sudo cp -R include/* /usr/include
echo -e "create /usr/lib/libv8_libplatform.a\naddlib out/native/obj.target/tools/gyp/libv8_libplatform.a\nsave\nend" | sudo ar -M
```
If you don't want to overwrite the system copy of v8, replace `/usr` in
the above commands with `/tmp/v8-install` and then add
`--with-v8js=/tmp/v8-install` to the php-v8js `./configure` command below.
`libv8_libplatform.a` should not be copied directly since it's a thin
archive, i.e. it contains only pointers to the build objects, which
otherwise must not be deleted. The simple mri-script converts the
thin archive to a normal archive.
Compile php-v8js itself
-----------------------
```
cd /tmp
git clone https://github.com/preillyme/v8js.git
cd v8js
phpize
./configure
make
make test
sudo make install
```

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
```

COMPILING LATEST VERSION
========================
Instead of compiling manually you might want to pull from the [V8Js docker
repository](https://registry.hub.docker.com/u/stesie/v8js/). Compiling latest version
------------------------
For some very first steps, instead of compiling manually you might want to try out the [V8Js docker
image](https://registry.hub.docker.com/u/stesie/v8js/). It has v8, v8js and php-cli pre-installed
so you can give it a try with PHP in "interactive mode". There is no Apache, etc. running however.
