0compile 0.14 ("now less annoying")

0compile 0.14 has been released:

  http://0install.net/0compile.html

The normal way of using 0compile has changed. Before, it selected a
set of versions at setup time and stayed with them unless you ran
setup again. That turned out to be quite annoying (and confusing).

Now, it chooses the best versions each time you build. If the versions
have changed since the last build, it will say what has changed and
abort. You can then use:

--clean for a clean build (slow but safe),

--force to use the new versions without cleaning (fast but unsafe), or

you can copy the previous version (the build-environment.xml file)
somewhere safe and tell it to use those versions (set the "selections"
line in 0compile.properties to its path).

The 0compile-env.xml file has gone, replaced by a much simpler
0compile.properties file (.ini-style). A typical file looks like this:

[compile]
interface = http://rox.sourceforge.net/2005/interfaces/ROX-Filer
metadir = 0install
download-base-url =
version-modifier =
selections =

Am trying to use Rox under Linux Mint, am getting the following Python traceback

What is the owner and permissions on that? To find out:

$ ls -l /home/jeb/.cache/0install.net/injector

It should be owned by you (not root, for example).

Ooops. I meant (with -d):

$ ls -ld /home/jeb/.cache/0install.net/injector

Re: assert gui_policy.ready -- error found under Mint

Thanks, Thomas.  It was set to 'root', because this being Mint, I tried to run it all using gksudo.  Does ROX work with sudo?  I fixed the permissions (all of them, there were several), and now when I try to install ROX-Session it asks for my root password...which does not exist   Do I just need to temporarily create a root user?

J.E.B.

Hi Jonathan,

Generally you should run everything as a normal user, and it will
prompt you if it needs root access.

Probably we should add some kind of warning to 0launch in case people
try to run it as root but with $HOME set to a normal user's home
directory.

Try this to set the root password:

$ sudo passwd root

ROX-Session should really be updated to use sudo.

HTH,

I've changed 0launch so that if it is run as root, but $HOME isn't
owned by root, then it gets root's home directory from /etc/passwd and
uses that for the configuration, cache and gpg stuff:

http://repo.or.cz/w/zeroinstall.git?a=commit;h=8fcff7446ffe8d26d87a166039088c7db060f17c

That means you can still use "sudo 0launch" if you really do want to
run a program as root.

Quick work   Thanks!  Query:  Does zi work with both Python 2.4 and 2.5?
