## Desktop Apps

Desktop apps created with Xojo have these requirements:

|     |                                                                                                                |                                                                                                                           |                                                                                                                                                                                                                                    |                                                                   |
|-----|----------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------|

## Web Apps

Web apps consist of two parts: user interface and the app itself. Your users can use a web app in one of the following browsers for these platforms:

|         |                                                           |                                           |                             |                  |                       |                 |
|---------|-----------------------------------------------------------|-------------------------------------------|-----------------------------|------------------|-----------------------|-----------------|
| Browser | \- Chrome 37+ - Firefox 17+ - Internet Explorer 9+ - Edge | \- Safari 6.0+ - Chrome 37+ - Firefox 17+ | \- Chrome 37+ - Firefox 17+ | \- Mobile Safari | \- Chrome for Android | \- Raspbian Web |

The apps can be deployed to servers with these requirements:

|            |                                                                                                                                                                      |                                                                                                                           |                                                                                                                                                                                                               |                                                                   |

## Console Apps

Console apps do not have a user interface and run on systems with these requirements (or any of the server requirements listed for Web Apps):

|     |                                                         |                                                                                                                           |                                                                                                                                                                               |                                                                   |

|                                         |                                                                                                                    |

== Linux Information ==

Because various Linux distributions have different libraries installed by default, you may need to install additional libraries installed before your Xojo apps will run on Linux. At a minimum, Xojo requires these Linux libraries:

|                                         |           |                                               |
|-----------------------------------------|-----------|-----------------------------------------------|
| glib 2.0                                | GTK+ 2.20 | libwebkitgtk-1.0.0 or libgtkhtml (HTMLViewer) |
| glibc-2.11 (32-bit) glibc-2.14 (64-bit) |           | libsoup 2.4 (Xojo.Net.HTTPSocket)             |
| libstdc++.so.6.0.13                     |           |                                               |
| libicu 4.2+                             |           |                                               |

## 64-bit Configuration

For best results, create 64-bit Xojo apps for distribution on 64-bit Linux systems. If you have to distribute a 32-bit Xojo app on a Linux distribution, you need to ensure that the 32-bit libraries are installed. They are not installed by default, so you'll have to install them manually. Below are some command that might be helpful.

</div></td>
<td><div class="container computer_code">
<p>yum install libicu.i686</p>
</div></td>
</tr>
</tbody>
</table>

If you are still having trouble identifying necessary libraries, the ldd command might help. You can run from Terminal in the Xojo directory to return a list of libraries required by Xojo and their status on the system:

`ldd Xojo`

## International Components for Unicode (libicu)

Most recent Linux distributions have [libicu](http://site.icu-project.org) installed, but depending on the Linux distribution you may need to install it yourself. These command may be helpful:

<table style="width:7%;">
