# Eclipse OMR
The Eclipse OMR project is a set of open source C and C++ components that can
be used to build robust language runtimes that support many different hardware
and operating system platforms.
Our current components are:
* **`gc`**: Garbage collection framework for managed heaps
* **`compiler`**: Components for building compiler technology, such as JIT
compilers.
* **`jitbuilder`**: An easy to use high level abstraction on top of the
compiler technology.
* **`port`**: Platform porting library
* **`thread`**: A cross platform pthread-like threading library
* **`util`**: general utilities useful for building cross platform
runtimes
* **`omrsigcompat`**: Signal handling compatibility library
* **`omrtrace`**: Tracing library for communication with IBM Health Center
monitoring tools
* **`tool`**: Code generation tools for the build system
* **`vm`**: APIs to manage per-interpreter and per-thread contexts
* **`example`**: Demonstration code to show how a language runtime might
consume some Eclipse OMR components
* **`fvtest`**: A language-independent test framework so that Eclipse
OMR components can be tested outside of a language runtime

What's the goal?
================
The long term goal for the Eclipse OMR project is to foster an open ecosystem of
language runtime developers to collaborate and collectively innovate with
hardware platform designers, operating system developers, as well as tool and
framework developers and to provide a robust runtime technology platform so that
language implementers can much more quickly and easily create more fully
featured languages to enrich the options available to programmers.
It is our community's fervent goal to be one of active contribution, improvement,
and continual consumption.
Who is using Eclipse OMR?
=========================
* The most comprehensive consumer of the Eclipse OMR technology is the [Eclipse
OpenJ9 Virtual Machine](https://github.com/eclipse-openj9/openj9): a high
performance, scalable, enterprise class Java Virtual Machine implementation
representing hundreds of person years of effort, built on top of the core
technologies provided by Eclipse OMR.
* The Ruby+OMR Technology Preview has used Eclipse OMR components to add a JIT
compiler to the CRuby implementation, and to experiment with replacing the
garbage collector in CRuby.
* A SOM++ Smalltalk runtime has also been modified to use Eclipse OMR
componentry.
* An experimental version of CPython using Eclipse OMR components
has also been created but is not yet available in the open. (Our focus
has been dominated by getting this code out into the open!)
What's the licence?
===================

How Do I Use it?
================
## How to Build Standalone Eclipse OMR
The best way to get an initial understanding of the Eclipse OMR technology is to
look at a 'standalone' build, which hooks Eclipse OMR up to the its testing system
only.
### Basic configuration and compile
To build standalone Eclipse OMR, run the following commands from the root of the
source tree. For more detailed instructions please read [BuildingWithCMake.md](doc/BuildingWithCMake.md).
# Create a build directory and cd into it
mkdir build
cd build
# Generate the build system using cmake
cmake -Wdev -C ../cmake/caches/Travis.cmake ..
# Build (you can optionally compile in parallel by adding -j to the make command)
make
# Run tests (note that no contribution should cause new test failures in testing).
# Use the `-V` option to see verbose output from the tests.
ctest [-V]
### Building Eclipse OMR on Windows using Visual Studio
The following instructions below demonstrate the steps to build Eclipse OMR on Windows
using Visual Studios. In the example Visual Studio 11 2012 Win64 is being used.
You can easily switch this to the version of Visual Studio you would like to use.
# Create a build directory and cd into it
mkdir build
cd build
#generate the build system using cmake
cmake -G "Visual Studio 11 2012 Win64" ..
# Build
cmake --build .
# Run tests (note that no contribution should cause new test failures in "make test")
ctest
