Installation instructions for SML/NJ ------------------------------------ These are instructions for installing recent "working" versions of SML/NJ on Unix-like systems, including MacOX X with the developer tools installed. If you are running MacOS X but don't have the developer tools, you can install the system starting from the disk image that we provide. See MACOSXINSTALL for details. If you are running Win32, see WININSTALL. 1. If you are in a hurry (and you have network connectivity) ... ---------------------------------------------------------------- - Pick a place to do the installation, e.g. $ d=/usr/share/smlnj # or whatever you like $ mkdir $d $ cd $d - Download config.tgz, e.g. $ v=110.38 # or whatever is the version you desire $ wget http://ftp.research.bell-labs.com/dist/smlnj/working/$v/config.tgz - Gunzip and untar, e.g. $ gunzip and should match your host system.) Keep in mind that making selections in config/targets there are dependencies between packages. For example, eXene requires cml and cml-lib. The installer script "knows" about these dependencies and will automatically calculate the transitive closure of the "requires" relation for you. Still, if you do not have network connectivity, then you should have downloaded tarballs for the entire transitive closure. (If you didn't, the installer will kindly remind you.) if you select... | ... you need --------------------------------------------------------------- (always) | boot.-.tgz | runtime.tgz | src-smlnj | MLRISC.tgz | cm.tgz | compiler.tgz | smlnj-lib.tgz | ml-yacc.tgz | system.tgz | ml-yacc | ml-yacc.tgz | ml-lex | ml-lex.tgz | ml-burg | ml-burg.tgz requires: ml-lex | | smlnj-lib | smlnj-lib.tgz | pgraph-util | cm.tgz | cml | cml.tgz requires: smlnj-lib | | cml-lib | cml.tgz | eXene | eXene.tgz requires: cml, cml-lib | | ckit | ckit.tgz | ml-nlffi-lib | ml-nlffi-lib.tgz | ml-nlffigen | ml-nlffigen.tgz requires: smlnj-lib, | ckit | | mlrisc-tools | MLRISC.tgz | nowhere | requires: mlrisc-tools | | doc | - (currently unavailable) 2.2. Tweaking "preloads"... ---------------------------- - Before running the installer (but after unpacking the config directory), you can customize the set of libraries that are pre-loaded (either directly or via CM's "autoload" mechanism). For this, edit config/preloads before running config/new-install.sh (or config/install.sh). 2.3. Using a different ftp server (for a step-1.-like installation) -------------------------------------------------------------------- - If you have a local mirror for ftp.research.bell-labs.com/dist/smlnj, then you can speed up installation by pointing the automatic URL fetch mechanism there. The URL of the repository is stored in config/srcarchiveurl. Edit this file before running config/new-install.sh (or config/install.sh). 2.4. Using locally stored tarballs ----------------------------------- - This is like step 2.3. -- except the URL in config/srcarchiveurl should read something like file:///usr/src/packages/smlnj/working/110.38 (In other words, the URL should spell out the name of the local directory that happens to contain the tarballs. Notice that this method does not seem to work with certain versions of wget which do not understand the file:// scheme.) 2.5. What needs to be on my PATH? ---------------------------------- - You should include $d/bin into your PATH. 2.6. Which of all those files do I really need? ------------------------------------------------ After the installer completes, directory $d will be full of files and subdirectories. Not all of them are actually required if you want to use the system. In particular, if you are not interested in any of the source code, you can DELETE EVERYTHING EXCEPT: $d/bin $d/lib 2.7. Can I move files to another directory after the fact? ----------------------------------------------------------- Yes. Here is the procedure: Suppose you have installed everything under $d and now you want to move things to some other directory $e (e.g., e=/usr/share/smlnj): 1. Move (at least) $d/bin and $d/lib to $e: $ mv $d/{bin,lib} $e 2. Before running the "sml" command, set the environment variable SMLNJ_HOME to point to $e: $ export SMLNJ_HOME=$e If you want to put the contents of $e/lib somewhere else, then point CM_PATHCONFIG to wherever the path configuration file lives. (The default is $SMLNJ_HOME/lib/pathconfig.) You can also scatter around the contents of $e/lib. If you do so, you have to edit the path configuration file itself. See the CM manual for more information on path anchors and path configuration. 2.8 Forcing the installer to use a particular URL getter program ---------------------------------------------------------------- By default, config/new-install.sh (and config/install.sh) will attempt to use wget, curl, and lynx (in that order). If you already know which of these programs you want the installer to use, then set the environment variable URLGETTER to "wget", "curl", or "lynx", respectively. You can also set URLGETTER to any other command "foo" as long as it can be invoked as $ foo where is the URL you want to fetch and is the file name where the result will be stored. 3. Troubleshooting: ------------------- 3.1. You think you have network connectivity, but the installer fails --------------------------------------------------------------------- - You probably do not have any of the following commands available on your system: wget, lynx, curl. Failsafe remedy: Proceed according to step 2.1., using whatever other FTP client you have. Alternative remedy: If you have some other command-line tool to fetch URLs, make a wrapper for it (if necessary) so that it can be invoked with precisely two arguments: and . Then set the environment variable URLGETTER to the name of this (wrapped) tool and try running the installer. Example: Suppose you don't have wget but a wget-lookalike named "xget". You could then make a shell script that wraps xget, e.g. using a shell script "myxget" consisting of the single line: exec xget -nv -O $2 $1 Once you have myxget, simply run: URLGETTER=myxget config/install.sh ---------------------------------------------------------------------------- (*) config/new-install.sh is a newer version of our installer with major parts written in SML rather than as a shell script. Since it is fairly new it may still have some problems -- in which case you can fall back to the old config/install.sh.
