These instructions are for Unix/Linux users.
Version of V8 supported¶
You have to use v8 3.20, which is the version of the nodejs release:0.11.7. For future compatibility, this is a good thing to be synchronized to nodejs project.
Download and Compile V8¶
The V8 source can be obtained from the v8 website.
git clone git://github.com/v8/v8.git v8
Compile the v8 library:
cd v8 git checkout 3.20 make dependencies library=shared make -j8 x64.release
Use ia32.release if you are using a 32bits machine.
Install the v8 library and include headers:
mkdir -p /opt/v8/lib && cp ./out/x64.release/lib.target/libv8.so /opt/v8/lib mkdir /opt/v8/include && cp include/v8* /opt/v8/include
Modify the library path if needed (32bits)
Setup the v8 lib in the system paths:
echo "/opt/v8/lib" > /etc/ld.so.conf.d/v8.conf ldconfig
Compile MapServer with V8 Support¶
cd MapServer mkdir build cd build cmake -DCMAKE_PREFIX_PATH=/opt/v8 -DWITH_V8=yes ..
Compile and install: (from the build directory)
Verify the V8 support:
