The goal of the Rho project is to refactor the interpreter of the R language into a fully-compatible, efficient, VM for R using modern software engineering techniques. Rho is being carried out independently of the main R development and maintenance effort.
Currently the rho codebase is based off R-devel.
Compiling rho requires a GCC or Clang compiler with C++ 11 support and fortran support. In addition the following libraries must be installed: * boost >= 1.48.0 * libcurl >= 7.28.0 * zlib >= 1.2.5 * libbzip2 >= 1.0.6 * liblzma >= 5.0.3 * pcre >= 8.10 * libedit
Compilation of the LLVM JIT requires clang 3.4 or later and the matching version of the LLVM library (except building on clang 3.7 is currently broken).
Rho has been tested to compile on both Linux and Mac OSX systems.
To build with the LLVM JIT enabled:
./configure --enable-llvm-jit --enable-maintainer-mode make make check
For development builds, it is useful to set
-Wall -DNO_CELLPOOLS -DCHECKED_SEXP_DOWNCAST -fsanitize=address -O1in order to find bugs more easily.
The configure call may complain about missing recommended packages. The recommended packages can be obtained by running the script
It is tricky to build rho with JIT support on OSX. The following steps show how to build without JIT support.
First, you will need the XCode command line tools which provide clang and clang++. Additional dependencies you need are:
The above dependencies can be installed with e.g. Homebrew:
brew install gcc # Provides gfortran. brew install xz brew install pcre brew install boost
After fetching the dependencies you should be able to build. If your Homebrew folder is in your home directory you will need to add
~/homebrew/libas include/library directories:
CC=clang CXX=clang++ \ CFLAGS='-I/Users/me/homebrew/include -g -O2' \ CXXFLAGS='-I/Users/me/homebrew/include -g -O2' \ CPPFLAGS='-I/Users/me/homebrew/include' \ LDFLAGS='-L/Users/me/homebrew/lib' \ ./configure --with-x=no
USE_RINTERNALSmacro. This includes Rcpp, rJava, data.table, xts and all the packages that depend on them.
