I'm building a nix environment for dmd, and am having problems 
buiding dmd from source on it.

I'm following the instructions on the wiki:
http://wiki.dlang.org/Building_DMD

The first thing I've run into seems that the X64 instructions are 
out of date? it says to do "make -f posix.mak MODEL=64", but that 
doesn't seem to do anything...
Anyways, that's just minor detail.

I'm hitting a wall at building phobos, because of curl:
make -f posix.mak DMD=../dmd/src/dmd
/usr/bin/ld: cannot find -lcurl

I've isntalled curl via apt-get ("sudo apt-get curl"), and it 
seems to be installed. Just not in ld:
which curl
/usr/bin/curl
cd /usr/bin/ld
bash: cd: /usr/bin/ld: Not a directory

Bit of help on either of these two isues? Then I'll update the 
wiki.

make -f posix MODEL=64

is correct.

I don't use Ubuntu, but my guess is that it has a separate package (probably 
with devel in the name) which includes the static lib. Many distros don't 
include all of the stuff required to build against a library in the main 
package for a library - just the stuff required to dynamically link against it.

Indeed. Looks like I got confused with the message "no cpu

Most awesome. Got it to work installing "libcurl-dev".

I wasted about 30 minutes after trying every flavor of 
"curllib-[dev|devel]", then typoing the work "instal" without

I would have suggested searching the list of packages for anything containing 
curl, in which case, it should have been easy enough to figure out which one 
you needed. I'm sure that Ubuntu has a command for searching the list of 
packages rather than having to try and guess what a package is called.

But libcurl and libcurl-dev are likely different packages. Also apt-get

yes...?? If you type "apt-get install libcurl" and then press

Apt-get manages autoremovals too. Though granted, it's not as obvious
how to operate it. But then again, I'm a CLI type of person, so reading
manpages is second nature to me. YMMV. :)

But yeah, for package management, I say a resounding No to GUI apps...
what happens if, for example, you need to fix a broken X11 installation?
Over an SSH link? I still find CLI most reliable, not demanding on
bandwidth, and still far more expressive than GUIs. (Well, I guess
that's why I'm a programmer. :-P Most "normal" people don't think like
that.)

How do you coax different versions of dmd to pick up a different
dmd.conf file? The last time I tried it, all of them insisted on reading
/etc/dmd.conf, which, of course, only actually works for one.

Didn't know that's where it was. I think it also reads the one
that is in the same directory as it, no?

That's how the zip packages work in any case.

That's what I decided to do anyways, just use the zips, and add a 
simlink to the latest version in /usr/bin

The way i manage this sort of thing is by having symbolic links 
for all the usual dmd things (i.e. dmd, rdmd, catdoc, dmd.conf 
etc.), then have a script dmd_select that switches which versions 
they all point to (which are held in different directories).

Alternatively, you could create separate symbolic links for each 
version, with different names. Or just rename the executables 
(not a good solution).

The advantage of all of these is that you don't have to rewrite 
dmd.conf because the relative paths will be the same for all 
versions.

To quote the website (http://dlang.org/dmd-linux.html):

-------
dmd will look for the ini­tial­iza­tion file dmd.conf in the fol­low­ing
se­
quence of di­rec­to­ries:

1. cur­rent work­ing di­rec­tory
2. di­rec­tory spec­i­fied by the HOME en­vi­ron­ment vari­able
3. di­rec­tory dmd re­sides in
4. /etc/
-------

So, if you put dmd.conf in the same directory with the dmd binary, then it'll 
be specific that particular version.

The bigger problem is your path. If you have multiple versions of dmd in your 
path, the first will always win. If you want to be able to switch between dmd 
binaries, you end either having to explicitly give the path to dmd or having 
to set up some way to switch the version of dmd which is currently in your 
path (probably by having it be a symlink which you change).

Hehe, /usr/bin/ld is the linker. It said that it cannot find
the curl library. E.g. when you say -lcurl, it is prefixed
with "lib" and followed by ".so" and looked up in your
system's library directory which would be usr/lib/.
Now 64-bit made it more complicated. You basically have 2
systems installed. A 32-bit one and a 64-bit one, which cannot
share any libraries of course, since 32-bit code isn't
compatible with 64-bit code.
You will thus find /usr/lib64/ (for which /usr/lib/ is an
alternative name) and /usr/lib32/.

When I type: ls /usr/lib{32,64}/libcurl.so*
I see that I have curl as 32-bit in version 4.2.0 and as
64-bit in version 4.3.0:

/usr/lib32/libcurl.so
/usr/lib32/libcurl.so.4
/usr/lib32/libcurl.so.4.2.0
/usr/lib64/libcurl.so
/usr/lib64/libcurl.so.4
/usr/lib64/libcurl.so.4.3.0

Not that the full version is the corresponding actual file,
while the others are links to it. These "so-names" are used to
link against the library in general, a specific major or even
minor version.

If you do NOT have a 32-bit installation of curl in /usr/lib32
AND compile Phobos in 32-bit, it will fail.

Ok, now you know that "ld" is the linker program and not a
directory. "which" is on the other hand a tool that looks up
the location of a program as it would be found by just typing
its name on the command-line. It doesn't list libraries, just
executables in the directories given in the $PATH environment
variable. You can quickly take a look at it by typing

echo $PATH

The curl library actually comes with a program
(/usr/bin/curl) that is both a nice demo of what the library
can do and useful to download stuff from the command line or
in a shell script.
You may have noticed that all executables are in some */bin/
and all libraries in some */lib/ directory. You can rely on
that convention.
The split between /bin, /lib and /usr/bin, /usr/lib comes from
a time when fast storage was expensive and very limited in
capacity. The fast medium was mounted in the root "/" directory
with only the most commonly used programs and libraries in /bin
and /lib (that you can still find there today) and a magnetic
tape was mounted into /usr which had abundant storage capacity
but terrible seek times.

I hope that made Linux a bit less mysterious.

P.S.: The curl package on Debian and Ubuntu only contains the
executable, not the library. That's why it didn't work:
http://packages.debian.org/wheezy/amd64/curl/filelist

libcurl3 contains the libraries for versions 3 and 4:
http://packages.debian.org/wheezy/amd64/libcurl3/filelist

Also from that list it looks like Debian
uses /usr/lib/x86_64-linux-gnu/ where I said /usr/lib64/
earlier. I'm on Gentoo Linux. Sorry for any confusion. :)
