[newbie] miscellaneous on installation and web site

[Marco Maggi]

Ciao,

  I am a  True Beginner taking a look at  O'Caml; I hope not
to  be abusing  by posting  here rather  than  the beginners
list.

  I  think  I   successfully  compiled  ocaml-3.11.2  on  my
i686-pc-linux-gnu, but  there seems to be no  way to install
the package in  a temporary location via the  Linux de facto
standard DESTDIR environment variable;  is there a way to do
it?  (I am used to build custom packages.)

  The  web site[1]  is beautiful  (no  irony) but  a lot  of
informations look outdated, 4/5 years old; I see many O'Caml
related sites on  the Net.  Is there one that  I can take as
reference  for  the latest  news,  for  example about  still
maintained library packages?

TIA

You are a beginner (you told), you know there is a beginner list, and
you apoligize for not using it.

what about installing from your system package management first?
Are you using Debian or Ubuntu? 
"apt-get install ocaml" and you're done.

Are you using Fedora?
"yum install ocaml" and you're done.

Building OCaml from source is definitely not a beginners' question! :o)

I've not come across that way before (by which I mean "you learn a new thing
every day"!), the more usual way, which will work with OCaml, is to specify
a different root for the -prefix option when you run configure. make install
will then install OCaml there. I used to use that when compiling uses OCaml
on a machine for which I didn't have root and I used it just the other day
to compile OCaml 3.12.0 on Maemo so the switch definitely works.

All that said, what distro are you using? Debian and Fedora (and *BSD) all
have native packages for OCaml.

The Caml Hump I believe has up-to-date information as long as it's
submitted. I'm quite lazy and tend only to look for updates to libraries I
use when either I hit a bug or am installing on a new machine ...
www.ocamlcore.org is a pretty good place to start, I think.

If I understand correctly, in autoconf-style setups, the contents of
the DESTDIR variable are prepended to the configured prefix to obtain the
paths used for installation.  Thus you might install to /tmp/usr/bin/ocamlopt
even though the compiler is configured for /usr.

Unfortunately I don't believe the Caml build system supports such a feature.
One possible way of doing it might be to run "make install" inside a chroot,
but you would likely need a lot of additional tools present inside the chroot
for that to work.

As another poster has said, it's probably best to use the distribution
packages if possible, or else just directly write into the installation
location (using ./configure -prefix /path/to/install/dir).

If you are really a beginner, I will really recommend to you using your
distribution OCaml packages, no matter if its ocaml 3.10.2 or 3.11.2.

Debian and Fedora provide packages (apt-get install ocaml on Debian).

caml.inria.fr and the Hump is a pretty good place to start:
http://caml.inria.fr/cgi-bin/hump.fr.cgi

The site available here are also good points to start with:
http://caml.inria.fr/resources/index.fr.html
and especially
http://www.ocaml-tutorial.org/

Then you have ocamlcore.org related websites:
- http://www.ocamlcore.org: entry point of ocamlcore.org
- http://planet.ocamlcore.org: for the latest (general) news of the
  OCaml community
- http://forge.ocamlcore.org: participate to various OCaml projects 
  or create your own

The best way to compile and install OCaml (in my opinion) is via GODI.  The 
GODI installation instructions are clear and allow you to specify where the 
install should go.  Once installed, it's also easy to get all the other 
libraries you might want to use.

Yes.  It worked (it seems) by doing:

$ ./configure -prefix "${prefix}" ...
$ make world
$ make bootstrap
$ make opt
$ ./configure -prefix "${DESTDIR}${prefix}"
$ make install

Slackware.

Understood (IMHO submissions more than 3 years old should be
removed).  So am I correct  in saying that MLGMP is orphaned
and no maintained GMP/MPFR/... package exists?

This is just Debian/Ubuntu people working on the packaging (not the
library). But even if there has been no release for a while, it doesn't
mean that it is orphaned or unmaintained...

Try it to see if it is working.

Why?
How to install GODI?

GODI is a very nice package management system for OCaml, making it trivial
to install both OCaml and most OCaml libraries that are in common use. It
automatically downloads and installs libraries, and checks for
dependencies. I would recommend using it, unless perhaps if you are on one
of the previously mentioned OS's that already have good support for OCaml in
their native package management systems. Follow the link below, download
RocketBoost on the right, and follow the instructions. You can post to the
Beginner's List if you run into any trouble.
