Sagittarius Scheme System

What is this?

This is a free Scheme implementation, supporting R6RS and R7RS specification.

How to build and install?

Sagittarius uses CMake for its building infrastructure. If you do not have it on your platform, please install it.

Quick build/install (for Unix like environment)

If your environment already has required libraries and just want to install to default location, run the following commands in the directory contains Sagittarius source code;

% cmake .
% make
% make install

Following sections describes more details.

Preparation for Unix-like environment

Sagittarius depends on the following libraries.

If you are using Linux which supports apt-get, then you can simply execute the following command:

% apt-get install libgc-dev, zlib1g-dev libffi-dev

Manual installation of Boehm GC

For Boehm GC, you need to install it with the option --enable-threads=pthreads. If your CPU is not incredibly old, you can also specify the option --enable-parallel-mark.

If you are too lazy to download the archive file of GC, CMake will download it for you. Make sure to run the following commands from in GC directory:

% ./configure \
      --enable-threads=pthreads   \
      --enable-parallel-mark      \
      --enable-large-config
% make
% make install

Note: most of the Linux distributions already have Boehm GC in their package management system, such as apt-get. I recommend to use it for security reason.

Building on Unix-like environment

After installing CMake and dependent libraries, you are ready to build Sagittarius; type the following command:

% cmake .

Note: The above command assumes you are in the source directory.

It is possible to build Sagittarius in a directory that is not the top source directory of the distributed package (out-of-tree building); for example:

% mkdir build
% cd build
% cmake ${path to Sagittarius' source directory}
% make

To run the tests, specify test target.

% make test

To install Sagittarius non default location, you need to specify CMAKE_INSTALL_PREFIX variable.

% cmake . -DCMAKE_INSTALL_PREFIX=/path/to/install

On some environment, there are 64 bits runtime specific directories such as lib64. To install Sagittarius runtime in the directory, then you can specify LIB_DIR variable as the following:

% cmake . -DLIB_DIR=lib64

Then the runtime install directoy will be CMAKE_INSTALL_PREFIX/LIB_DIR. There are also the variables to specify bin, include and share directories, and the directory for the .pc files; BIN_DIR, INCLUDE_DIR SHARE_DIR, and PKGCONFIG_DIR, respectively.

Since 0.5.6, Sagittarius's REPL is renamed to sagittarius and legacy sash is kept as a symbolic link. If you don't need the symbolic link then you can put the INSTALL_SYMLINK option off as the following:

% cmake . -DINSTALL_SYMLINK=0

After a successful compilation, it is possible to install Sagittarius to the location specified by CMAKE_INSTALL_PREFIX or default system location if it's not specified with the command:

% make install

After installation, you might need to run ldconfig to run Sagittarius properly.

Note: For some reason, you might want to build a 32-bit runtime on a 64-bit platform. The following command can be used for this purpose;

% cmake . \
    -DCMAKE_CXX_COMPILER=${your 32 bit C++ compiler} \
    -DCMAKE_C_COMPILER={your 32 bit C compiler}

Make sure you have all the required 32-bit executables and libraries.

Building on Mac OS X

Only with Homebrew is tested.

Installing libffi, CMake, and Boehm GC.

$ brew install libffi cmake bdw-gc

After installing dependent libraries, the rest of the process are the same as Unix-like environment.

If cmake can't find libffi, then you can specify the location via FFI_LIBRARY_DIR option like the following.

$ cmake . -DFFI_LIBRARY_DIR=/usr/local/Cellar/libffi/3.0.13/lib

Note: some Mac OS X environment may not be able to find ar command because /usr/bin/gcc is identical as /usr/bin/clang. In that case, export CC and CXX environment variable with proper GCC and G++ command path respectively so that CMake can find the command.

Building on FreeBSD

FreeBSD has multiple type of Boehm GC system libraries; gc, gc-threaded and gc-redirect. Sagittarius requires threaded runtime to make thread library works properly. The building process checks if gc has GC_get_parallel() function and if it doesn't then tries to use gc-threaded library. Please make sure your system has gc-threaded or gc built with multi thread option.

NB: If you install gc without build option, then default is without thread support. In such a case, you need to install gc-threaded as well.

Building on Windows (non Cygwin environment)

On Windows, you need to create an installer and Sagittarius is using innosetup for it. Please install it.

You need to install MSVC preferably Visual Studio 2010 or higher. And if you use cmake-gui, it will be much easier. Run Visual Studio Command Prompt and go to the directory which Sagittarius source codes are expanded.

If you prefer to use cmake instead of cmake-gui, then the following command needs to be executed:

% cmake . -Denable_threads=ON -Denable_parallel_mark \
     -G"NMake Makefiles"

Specifying -DDEBUG_VERSION=OFF enables MSVC optimisations.

The final commands are almost the same as in Unix-like environments.

% nmake
% nmake test

After these commands, you move to the win/ directory and double click the file innosetup.iss. Go to [Build] - [Compile], then it will create the installer. For more detail, please see Inno Setup's document.
