[Nix-dev] build question

Hi Roelof,

usually on mailinglists "bottom posting" is used.
This means you copy *only* the text you refer to from emails and then
put your reply below it.

When nix runs the build process it defines a special env var called
$out. Its the store path you should install into.

Goto the setup.sh file I pointed you to in my previous mail. You'll find
this code:

if test -z "$prefix"; then
    prefix="$out";
fi

if prefix is not yet set set it to $out.

Then in the configurePhase the --prefix=$prefix is added using some more
shell magic:

configureFlags="${prefixKey:---prefix=}$prefix $configureFlags"

Also have a look at some existing gnome packages - for example
libgnomeprint:

pkgs/desktops/gnome-2.28/platform/libgnomeprint/default.nix

You'll see that the defaults for configure && make etc work fine because
no special treatment can be found in that file.
