Berkelium copyright (C) 2009-2010 The Sirikata team.
Berkelium is a BSD licensed library that provides off-screen browser rendering
via Google's open source Chromium web browser. See for a
detailed overview.
==== Building:
For Windows instructions, see WINDOWS-BUILDING.txt in the win32/ folder.
For Mac or Linux, first use the automated script to build chromium:
You can specify options to it, see --help for more information. The most
important option is probably --deps, which on supported platforms (e.g. Ubuntu,
Fedora), will try to install required dependencies from system packages.
For a Debug build of chromium, export CHROMIUM_DEBUG=true
Warning: Debug requires 4GB RAM and 64-bit Linux or Mac OS X 10.6
I highly recommend *not* building Chromium in Debug.
Link times without debug are ~15 seconds.
With debug, about 5 minutes with heavy disk access.
To build, you need CMake 2.4 or higher installed (2.6 recommended)
To generate a Makefile, run:
I recommend building Berkelium in Debug, no matter how Chromium was built:
cmake . -DCMAKE_BUILD_TYPE=Debug
(If you are using debug Chromium, specify -DCHROME_MODE=Debug)
To build Chromium, run:
==== Release build:
Run cmake with:
cmake . -DCMAKE_BUILD_TYPE=Release
On mac, there is a script which will replace hardcoded absolute paths
with relative paths, as well as do all the packaging:
On Linux, just run "make" again, and copy the created executables. I recommend copying "" from chromium/src/out/Debug for video tag support, as well as any other plugins you may want to include.
