Does anyone have a good solution to installing both D1 and D2 on the same system?

Possible solutions:

 * Rename the D2 dmd binary to dmd2 and make sure it uses a different config file for each to use the right libs.
 * Install them in different directories and use a script to update your $PATH depending on if you want to use D1 or D2
 * Create a script that uses a different version of dmd depending on what parameters you pass to it (eg dmd -1 or dmd -2).
 * The simplest solution would probably be something like the following (on non-windows OSes):

alias dmd='/path/to/dmd1/binary/here'
alias dmd2='/path/to/dmd2/binary/here'

This will allow you to use dmd to compile D1 and dmd2 for D2.

That's what I was thinking...

but IIRC the last time I tried that it didn't work to well but I seem to recall something being done about that. What is the sugested way to make this bit work?

Of course, using /home/georg/dcompilers/dmd1042 or whatever, would be the same, unless I want others to use D, too.

(The zip files aren't of course needed, but that's as good a place as any to store them if I don't want to delete them after unzipping.)

I don't add the dmd directories to the path, edit dmd.conf, or do anything else. Except, of course chmod +x dmd   :-)

I have... (goes to check) 10 different compilers on my system.  There's \dmd\bin\dmd-default which is the only one on the PATH (and is basically a stable version of Tango and DMD).  If I want to use the others, I use the full path to them.

OR, you can use rebuild and configure it with extra compiler profiles,
then use (for example):

> rebuild -dc=dmd-1.035 stuff

So the dmd.conf in the same dir just works? Sweet, last time I tried it it didn't.

Yeah, this seems to have changed. Now dmd just works without acrobatics.

Naryl made it available on Gentoo. The two versions will get installed into different slots (sepcialtiy of the portgae package manager), and it works great. Switching between different profiles (eg. dmd1-phobos or dmd2-phobos, etc.) is done by the "eselect" Gentoo utility.
