Inno Setup

We use Inno Setup to create Windows installers for Syncany. To completely integrate the exe-generation with the build process, we created a small Gradle task (exe) for it.

1. Download and install Inno Setup

To use the exe task, you must first install Inno Setup and add its program directory to your PATH variable. Especially, the "iscc.exe" must be runnable by Gradle.

1.1. On Windows
  1. Download and install Inno Setup
  2. Add "C:\Program Files\Inno Setup 5" to your PATH variable
1.2. On Linux
  1. Install the Windows emulator Wine
  2. Download Inno Setup and install it via Wine
  3. Copy the wrapper script iscc to /usr/local/bin

In short:

sudo apt-get install wine
wget http://www.jrsoftware.org/download.php/is.exe
wine is.exe
sudo cp iscc /usr/local/bin/iscc

If the machine has no display manager, Inno Setup cannot be installed. Instead, you can extract the is.exe file using innoextract. The innoextract tool is available in many distro repos (e.g. Ubuntu >= 12.10, Debian >= 7). So in most cases, the following commands are enough:

sudo apt-get install innoextract
innoextract is.exe
mkdir ~/".wine/drive_c/Program Files (x86)/Inno Setup 5"
cp -a app/* ~/".wine/drive_c/Program Files (x86)/Inno Setup 5"

In case innoextract is not available, use the author's repo:

sudo apt-get install python-software-properties     (for the add-apt-repository command)
sudo add-apt-repository ppa:arx/release
sudo apt-get update
sudo apt-get install innoextract

2. Create exe-installer with the Gradle "exe" task

The Gradle task "exe" first copies the skeleton input script setup-cli.iss.skel and replaces some variables (application version). It then calls the Inno Setup compiler (ISCC) with this script and generates an exe-file to syncany-cli/build/innosetup.

After all that you should be able to run iscc from the command line; and hence Gradle should also be able to use the iscc compiler. You can run it like this:

gradle exe
