Setting up the Inno Setup compiler on Debian

Posted on by Andre Beckedorf

I’m currently setting up a nightly build system for Quasar on my Linux box which is running Debian. This system also cross-compiles Quasar for Windows.
The Windows version of Quasar is going to be available in two fashions: one self-contained, portable version and one version that can be installed.
I’m not a huge fan of installers. But when it comes to creating a setup program for a given Windows application I’m quite accustomed to Inno Setup having used it for years. Unfortunately there is no native Linux version of the Inno Setup compiler available for Linux. NSIS exists as package for Debian but I am not fond of using it, largely because I am a Delphi guy. :)
So, here is a small guide on how to get the Inno Setup compiler up and running on Debian:

First step is to install Wine either as super user or by using sudo:

sudo apt-get install wine

As normal user fire up your X server and your favourite terminal application and get the latest Inno Setup QuickStart pack:

mkdir /tmp/innosetup
cd /tmp/innosetup
wget http://files.jrsoftware.org/ispack/ispack-5.2.3.exe
wine ./ispack-5.2.3.exe

This will start the installer in Wine. Note, for the installation you will need a running X11 server since the installer obviously is graphical. If you have not set up Wine before, the default location C:\Program Files\Inno Setup 5 will install to ~/.wine/drive_c/Programme/Inno Setup 5.

Luckily the Inno Setup compiler offers a command line interface, ISCC.exe, which will run in Wine without the necessity of having a X server running. So it is ideally suited for automated runs.

Here is a simple wrapper shell script called iscc:

#!/bin/sh
unset DISPLAY
scriptname=$1
[ -f "$scriptname" ] && scriptname=$(winepath -w "$scriptname")
wine "C:\Program Files\Inno Setup 5\ISCC.exe" "$scriptname" "$2" "$3" "$4" "$5" "$6" "$7" "$8" "$9"

I installed this script in my local bin directory (~/bin) and added it to the PATH environment variable.
This will allow running the Inno Setup compiler from anywhere and it also makes it very easy to integrate into a build script. You can even feed a script via stdin, e.g. something like:

iscc - < ./myscript.iss

vpopmail – maildrop – SqWebMail mailfilter patch

Posted on by Andre Beckedorf

On our production mail server we’re using a so called qmail toaster setup. It’s essentially the same setup as described by shupp.org. However, instead of using SquirrelMail for webmail, we opted for SqWebMail and maildrop. The nice thing about SqWebMail is that it offers a web interface for configuring the maildrop mailfilters. That way, every user can configure their filtering rules individually.

The problem here is that vdelivermail (of vpopmail) doesn’t support those mailfilter files. For that to work we need vdelivermail to call maildrop to process those files on an individual basis. However, this requires to setup the processing instructions for every mail account manually. Of course, this is unbearable on a large setup.

We came up with a patch for vdelivermail that automatically chain-calls maildrop if it finds a mailfilter file in the domain’s account directory. Some parts are based on another patch which source I forgot. I mainly extended it to be less strict and to publish certain internal vpopmail/vdelivermail variables as environment variables that could be used inside the mailfilter – namely username, userdir, domainname, domaindir.

If it finds the file in the domain’s directory, it will delegate the mail to the domain-wide mailfilter.
The domain-wide mailfilter will delegate the mail to the users mailfilter if it exists. If not, it will simply do a standard mail delivery to the account’s INBOX.

If vdelivermail can’t find any domain-wide mailfilter it will simply default to standard mail delivery to the account’s INBOX.

Here is the patch against vpopmail 5.4.17:

vpopmail-5.4.17-vdelivermail.c-maildrop.patch

If you’re too lazy to patch the vpopmail sourcecode yourself, here is the already patched vdelivermail.c:

vdelivermail-5.4.17-maildrop.c

(Rename it to vdelivermail.c and place it in the vpopmail source directory and compile.)
