What's a beta?

Beta means that while the app already runs very well, there could still be a few rough edges when you do something that I haven't expected.

Cauldron is in public beta since April 2013 and will continue to be in beta for a few months after that, but it's stable and has all the important features with more being added every week, so right now is the perfect chance for you to give it a try and use it completely free of charge.

If something doesn't work right, you can report the problem to me on app.net: @chriscolon and I will try to fix the problem as soon as possible.

Generic Linux Installation Instructions

(a .deb for Ubuntu/Debian will be available once the app is out of beta)

Open a terminal and change into the folder where you downloaded the filename.tar.gz

tar xvf filename.tar.gz
cd cauldron

If you want to, you can symlink the executable cauldron somewhere on your path or on your desktop as an icon. If you need an Icon, you can download the image above the download menu on this website.

If you're using Gnome 3, right click on the cauldron executable, choose Make Link. Drag and drop the link to your desktop, right click it and choose properties, then click on the square button in the top left to set an icon.


Arch Linux - Crashes at launch

Due to a bug in the current version of node-webkit, the platform Cauldron runs on top of, you need to install ttf-ms-fonts from the AUR to use Cauldron right now.

Missing library libudev.so.0 on some Linux distributions

Some Linux distributions use a newer version of libudev.so without providing the older one, which breaks some apps, including node-webkit which Cauldron uses.

To solve this problem, copy your version of libudev.so into the cauldron folder and rename it to libudev.so.0, then start Cauldron with:

LD_LIBRARY_PATH=. ./cauldron

Make sure that you copy the version that is right for your architecture. So if you use the 32 bit version of Cauldron, copy the 32 bit libudev.so, if you're using the 64 bit version, use the 64 bit libudev.so.

Where to find libudev.so

If you're using Ubuntu 13.04, you will need to install libudev1 first:

sudo apt-get install libudev1

On Ubuntu 13.04, libudev.so can be found here:

32 bit: /lib/i386-linux-gnu/libudev.so.1.2.2

64 bit: /lib/x86_64-linux-gnu/libudev.so.1.2.2

On Fedora 18, it can be found here:

32 bit: /usr/lib/libudev.so.1.2.1

64 bit: /usr/lib64/libudev.so.1.2.1

If you use Google Chrome to download Cauldron, after the download has finished Chrome might tell you that the file could be dangerous. You can safely ignore that warning, Chrome says this about every unsigned .exe file as a precaution without actually checking the file.

Just click on the little triangle to the right of the download in Chrome once you see the warning and select the option to keep the file.
