Welcome to Open Dylan!
Open Dylan is a compiler and a set of libraries for the Dylan programming language. If you're interested in working on the compiler and core libraries then you've come to the right place. If you want to write your own Dylan libraries and use the compiler then you should download a binary release and then read the Getting Started guide.
Open Dylan has two back-ends, HARP (which translates to native x86 code) and a C back-end.
The HARP back-end uses the Memory Pool System (MPS) from Ravenbrook, Limited to do its memory management. The MPS is available from Ravenbrook at http://www.ravenbrook.com/project/mps/ and must be downloaded and built separately.
The C back-end uses Boehm-Demers-Weiser conservative C/C++ garbage collector, available at https://github.com/ivmai/bdwgc
Open Dylan is written in Dylan, thus a Dylan compiler is needed to bootstrap it. Binary releases are available from http://opendylan.org/download/
Once installed, the following command-line will produce a binary in ~/Open-Dylan/bin/hello-world
dylan-compiler -build hello-world
Compilation of the compiler itself
Clone the git repository:
git clone git://github.com/dylan-lang/opendylan.git --recursive
Compilation on UNIX
Please note that on 64 bit Linux we need a big stack, the default stack is too small, please increase with ulimit -s before (safe is to double its value)
- Get MPS or boehm-gc, depending on your platform:
- Linux x86 or FreeBSD x86 (HARP) -> MPS
- Mac OS X and all 64 bit (C) -> boehm-gc
./autogen.sh ./configure \ --with-mps=/path/to/mps-kit \ # if using the HARP back-end --with-gc=/path/to/gc \ # if using the C back-end --prefix=/opt/opendylan-current make sudo make install
The first generation will be in Bootstrap.2/bin/dylan-compiler , and a second generation will be in /opt/opendylan-current/bin/dylan-compiler
Compilation on Windows
Make sure to have required tools installed: namely Debugging tools for Windows, a C compiler (PellesC or VC6) and Microsoft Platform SDK.
Open a shell (windows command processor), there set the environment variable SDK4MEMORY_POOL_SYSTEM to <where you unpacked MPS>.
Please keep in mind that paths with whitespaces are not well supported.
Go to admin\builds and do a:
build-release.bat <target-dir> /sources <git-checkout>sources /internal
This will do a 4-stage bootstrap, in the end there will be a complete IDE in <target-dir>.
- Building an installer:
- Get NSIS from http://nsis.sf.net and the HTML help workshop (from Microsoft, to generate the chm).
- Go to packages\win32-nsis, read Build.txt and follow the instructions. Make sure you are using the same command shell as used for building Open Dylan (to retain environment variables).
Building the MPS
This is not required anymore since it is part of building the runtime.
Go to the 'code' subdirectory in the MPS sources and build the mmdw target:
nmake /k /f w3i3mv.nmk mmdw.lib
make -f lii4gc.gmk mmdw.a mpsplan.a The actual makefile you use may differ depending on your platform. See the readme.txt file in the MPS distribution for a list. glibc >=2.3 and linux kernel >= 2.6 required For MPS 1.106.2 I (cgay) encountered this problem on Ubuntu 7.10: http://www.ravenbrook.com/project/mps/issue/job001637/ The solution was to replace #define _POSIX_C_SOURCE 1 with #define _XOPEN_SOURCE 500 in both prmcli.h and pthrdext.c. The comments in the above URL weren't explicit about that. For MPS 1.106.2 and 1.108.0 I (cgay) encountered this problem on Ubuntu 11.04: cc1: warnings being treated as errors protlii3.c: In function ‘sigHandle’: protlii3.c:115:3: error: case label is not an integer constant expression protlii3.c:116:3: error: case label is not an integer constant expression make: *** [lii4gc/hi/protlii3.o] Error 1 make: *** [target] Error 2 make: *** [mmdw.a] Error 2 To work around it edit gc.gmk to remove -Werror from CFLAGSCOMPILER.
The main point to notice here is that you don't just build the default target, as described in the MPS documentation. You must build mmdw.lib or mmdw.a instead.
The above instructions use the ci, "cool internal" variant of the MPS on Windows. On Linux, MPS_VARIANT=hi is specified in opendylan/sources/lib/run-time/pentium-linux/Makefile.in. The ci variant does quite a lot of sanity checks all over, which heavily impacts performance, up to a factor of three in total application runtime. If you're looking for performance figures, use the hi, "hot internal", or even wi, "white-hot internal" releases.
