V8 MonoContext shared library

Used to run javascript files within one v8 context

Basically intended to be used as a library in V8::MonoContext(perl), PyV8Mono(python)

V8 dependence

We prefer to build MonoContext with strict v8 version to get stable and predictable behavior in production and not to depend from variety of changes occuring in v8 trunk.

INSTALLATION

Currently all installation process is tested on CentOS release 6.5 (Final) x86_64 and can be made with any modern linux distribution

First of all prepare gcc, v8 library and environment

Use gcc version >=4.7.0 If you have a proper gcc version installed under prefix location:

$ export CXX=/usr/local/gcc-4.7.3/bin/c++ 
$ export LINK=/usr/local/gcc-4.7.3/bin/c++

Strict v8 version

$ export V8_VERSION=3.27.0
$ export V8_PREFIX=/usr/local/v8-$V8_VERSION

Clone last V8 source trunk, build dependencies and checkout 3.27.0

$ git clone git://github.com/v8/v8.git v8 && cd v8 
$ git checkout 3.27.0 
$ make dependencies

Build V8 with the following recommended flags

$ make \
  objectprint=off \
  i18nsupport=off \
  verifyheap=off \
  debuggersupport=on \
  regexp=native \
  vtunejit=off \
  extrachecks=off \
  visibility=on \
  snapshot=on \
  strictaliasing=on \
  liveobjectlist=off \
  backtrace=on \
  gdbjit=off \
  disassembler=off \
  werror=no \
  library=shared \
  soname_version=$V8_VERSION \
  x64.release

Install libs and headers in prefix location

$ sudo -E bash -c 'mkdir -p $V8_PREFIX/{bin,include,lib64}'
$ sudo -E bash -c 'install -D -m 755 out/x64.release/{cctest,d8,lineprocessor,mksnapshot.x64,process,shell} $V8_PREFIX/bin'
$ sudo -E bash -c 'install -D -m 644 include/*.h $V8_PREFIX/include'
$ sudo -E bash -c 'install -D -m 755 out/x64.release/lib.target/libv8.so.$V8_VERSION $V8_PREFIX/lib64'

Configure dynamic linker

$ sudo -E bash -c 'echo "$V8_PREFIX/lib64" > /etc/ld.so.conf.d/v8-$V8_VERSION.conf'
$ sudo ldconfig

Finally build and install v8monoctx.so shared library

$ git clone https://github.com/fsitedev/v8monoctx.git v8monoctx
$ cd v8monoctx
$ make
$ sudo -E bash -c 'make install'
