1 ## Identifying your system ##
3 We'll assume you're using either Mac OS X, or Windows, or Linux.
5 If you're using **Mac OS X**, take note of what version of the Mac OS you're
6 running: "Tiger" 10.4, or "Leopard" 10.5, or "Snow Leopard" 10.6. Furthermore,
7 you'll be in one of two subgroups:
9 * You'll have Apple's Xcode and the independent MacPorts system
13 <http://developer.apple.com/technologies/tools/xcode.html>.
14 You have to register as an Apple Developer to download it. This
15 is free but requires you to accept a legal agreement with Apple.
16 The latest version of Xcode to work with Leopard is 3.14; more
17 recent versions require Snow Leopard.
19 The MacPorts system is available at
20 <http://www.macports.org/>.
21 This automates the building of Unix-type software on your Mac; it
22 makes it a lot easier to check for dependencies, use more-recent
23 versions of things, and so on.
25 * Or you won't have those installed. (Most Mac users will be in this group.)
26 Then you'll need pre-packaged (and usually pretty GUI) installers for
27 everything. These are great when they're available and kept up-to-date;
28 however those conditions aren't always met.
31 If you're using **Windows**, you'll be in one of two subgroups:
33 * You'll have the Cygwin system
34 <http://www.cygwin.com/> installed.
35 This puts a Unix-like layer on top of your Windows system,
36 and makes it easier for you to use the same software everybody
37 else will be using, without its needing as much special-for-Windows
38 treatment. However, many of you won't have this installed.
40 * You won't have Cygwin installed. You might in theory have
41 a different group of compilers installed (Microsoft Visual C++) but
42 we'll assume that the overwhelming majority of users in this group
43 don't have access to a compiler and need pre-packaged installers
46 If you're using **Linux**, you could be using any one of numerous packaging
49 * We'll give examples using the packaging system shared by Debian and Ubuntu,
50 and we'll assume that those of you using different packaging systems will know
51 how to make the relevant substitutions. You may also want to take note of the
52 output of the "uname -srm" command. On my machine this tells me "Linux
53 2.6.35-ARCH x86\_64". That tells me I'm running the x86\_64 (as opposed to the
54 i686 or i386 or whatever) version of Linux, and that I'm running kernel
59 ## PLEASE REPORT PROBLEMS (AND SOLUTIONS!) ##
61 We haven't tested these instructions ourselves, and they're not explicit
62 step-by-step instructions in any case. If you encounter troubles, please email
63 to let us know so that we can amend the instructions to help others. If you
64 figure out how to fix the problem youself (and please do), please also write
65 with suggestions how we can change these instructions to make the process
66 easier and more straightforward for others.
71 **Scheme** is one of two major dialects of *Lisp*, which is a large family of
72 programming languages. The other dialect is called "CommonLisp." Scheme is the
73 more clean and minimalistic dialect, and is what's mostly used in academic
76 Scheme itself has umpteen different "implementations", which share most of
77 their fundamentals, but have slightly different extensions and interact with
78 the operating system differently. One major implementation used to be called
79 PLT Scheme, and has just in the past few weeks changed their name to Racket.
80 This is what we recommend you use. (If you're already using or comfortable with
81 another Scheme implementation, though, there's no compelling reason to switch.)
83 Since the name change is so recent, you're likely to run across both sets of names.
85 PLT Scheme had several components. The two most visible components for us
86 were the command-line interpreter "mzscheme" and a teaching-friendly editor/front-end "DrScheme". In
87 Racket these have been renamed "racket" and "DrRacket",
91 * **To install in Windows**
93 Go to <http://racket-lang.org/download/>. Download and install the "Windows x86" version.
95 * **To install on Mac without MacPorts**
97 Go to <http://racket-lang.org/download/>. Download and install the option for your system, most likely "Macintosh
100 * **To install on Mac with MacPorts**
102 You can install a command-line version of
103 PLT Scheme (dating from early 2009) by opening a Terminal
106 sudo port install mzscheme
108 If you want the GUI components, I think you'll need to use the
109 "Mac/without MacPorts" installation options above.
111 I recommend also typing:
113 sudo port install rlwrap
115 then if you ever use the command-line program `mzscheme` (or `racket`), you should start it by typing `rlwrap mzscheme`. This gives
116 you a nice history of the commands you've already typed, which you can scroll up and down in with your
119 * **To install on Linux**
121 Use your packaging system, for example, open a Terminal and
124 sudo apt-get install plt-scheme
126 It's very likely that your packaging system has some version of
127 PLT Scheme (or Racket) available, so look for it. However, if you can't find it you
128 can also install a pre-packaged binary from the Racket website at <http://racket-lang.org/download/>.
129 Choose the option for your version of Linux (Ubuntu, Debian, and two
130 varieties of Fedora are available).
132 As above, I recommend you also type:
136 then if you ever use the command-line program `mzscheme` (or `racket`), you should start it by typing `rlwrap mzscheme`. This gives
137 you a nice history of the commands you've already typed, which you can scroll up and down in with your
143 **Caml** is one of two major dialects of *ML*, which is another large family of
144 programming languages. The other dialect is called "SML" and has several
145 implementations. But Caml has only one active implementation, OCaml or
146 Objective Caml, developed by the INRIA academic group in France.
148 It's helpful if in addition to OCaml you also install the Findlib add-on.
149 This will make it easier to install additional add-ons further down the road.
150 However, if you're not able to get that working, don't worry about it much.
153 * **To install in Windows**
155 Go to <http://caml.inria.fr/download.en.html>.
156 You can probably download and install the
157 "Self installer for the port based on the MinGW toolchain"
158 even if you don't know what MinGW or Cygwin are.
159 Some features of this require Cygwin, but it looks like
160 it should mostly work even for users without Cygwin.
161 At the time of this writing, only an installer for the previous
162 version of OCaml (3.11.0, from January 2010) is available.
164 To install the Findlib add-on, you must have the
165 Cygwin system installed. We assume few of you do,
166 so we're not going to try to explain how to do this.
167 If you want to figure it out yourself, go to the
168 Findlib website at <http://projects.camlcity.org/projects/findlib.html>.
170 * **To install on Mac without MacPorts**
172 To install OCaml 3.12 (just released this summer), go to
173 <http://caml.inria.fr/download.en.html>
174 and download and install the "Binary distribution for Mac OS X"
176 To install the Findlib add-on, you'll need the Xcode development tools
177 to compile it yourself. Once you get that far, it's probably easiest
178 for you to install MacPorts and just install things using the MacPorts
179 instructions. (Use the MacPorts version of OCaml, instead of installing
180 the package from the caml.inria.fr website, as described above)
181 However, if you do have Xcode, and want to do without MacPorts, then
182 what you need to do is download Findlib from
183 <http://download.camlcity.org/download/findlib-1.2.6.tar.gz>.
184 Unpack the download, open a Terminal and go into the folder you just
190 This will build an installer package which you should be able to
191 double-click and install.
193 * **To install on Mac with MacPorts**
195 You can install the previous version of OCaml (3.11.2,
196 from January 2010), together with the Findlib add-on, by opening a Terminal
199 sudo port install ocaml caml-findlib
201 As with Scheme, it's helpful to also have rlwrap installed, and to start OCaml as `rlwrap ocaml`. This gives
202 you a nice history of the commands you've already typed, which you can scroll up and down in with your
206 * [More details about installing OCaml on Macs, if needed](http://cocan.org/getting_started_with_ocaml_on_mac_os_x)
208 * **To install on Linux**
210 Use your packaging system, for example, open a Terminal and
213 sudo apt-get install ocaml ocaml-findlib
215 That will install a version of OCaml (probably 3.11.2, from January 2010)
216 and the Findlib add-on.
218 If for some reason you can't get OCaml through your
219 packaging system, you can go to
220 <http://caml.inria.fr/download.en.html>.
221 Pre-packaged binary installers are available for several Linux systems.
223 If you can't get findlib through your packaging system, you'll
224 need to download it from
225 <http://download.camlcity.org/download/findlib-1.2.6.tar.gz>.
226 and use gcc to compile it yourself. If you don't know how to
227 do that, you probably don't want to attempt this.
