About: ROSE is a compiler infrastructure to build source-to-source program transformation and analysis tools for large-scale C (C89 and C98), C++ (C++98 and C++11), UPC, Fortran (77/95/2003), OpenMP, Java, Python and PHP applications.

rose Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies
  4. rose- contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

ROSE Compiler

ROSE is an open source compiler infrastructure to build source-to-source program transformation and analysis tools for large-scale Fortran 77/95/2003, C, C++, OpenMP, and UPC applications. The intended users of ROSE could be either experienced compiler researchers or library and tool developers who may have minimal compiler experience. ROSE is particularly well suited for building custom tools for static analysis, program optimization, arbitrary program transformation, domain-specific optimizations, complex loop optimizations, performance analysis, and cyber-security.

Why Use ROSE

ROSE is not grep, sed, LLVM, or a Perl script. A ROSE Tool uses the ROSE compiler-based infrastructure to parse code into a complete Abstract Syntax Tree (AST). The AST contains all the syntax and semantic information in the original code, and has a rich API supporting sophisticated analysis and transformations. The ROSE Tool queries the AST and reports on and/or changes the AST, then may emit new code from the AST. All ROSE Tools can thus precisely replicate the parsing and semantic analysis behaviour of multiple compiler languages, vendors, and versions. New ROSE Tools can quickly be created by customers or by the ROSE Team. ROSE is open-source, and is portable across a large and expanding range of platforms. ROSE Tools can process large code bases, and the ROSE infrastructure and ROSE Tool collection are continuously upgraded and extended by the LLNL ROSE Team and outside contributors.

Installation Instructions

From the source tree run ./build. Then navigate to your build tree and run configure and make.

../src/configure --prefix=/path/for/ROSE/install \
                 --enable-languages=c,c++ \
make install -j${NUM_PROCESSORS}
make check -j${NUM_PROCESSORS}

For Ubuntu 18.04, we have experimental support for installating ROSE pre-built binaries packages using apt-get

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:rosecompiler/rose-development # Replace rose-development with rose-stable for release version
sudo apt-get install rose
sudo apt-get install rose-tools # Optional: Installs ROSE tools in addition to ROSE Core

For full install instructions go to
