<a id="Web Apps" name="Web Apps">Web Apps</a>

Web apps consist of two parts: user interface displayed in the web browser and the app itself.

<a id="Web Browser" name="Web Browser">Web Browser</a>

Your users can use a web app in one of the following browsers for these platforms:

<thead> </thead> <tbody> </tbody>

	Windows	Mac OS / Mac OS Server	Linux	iOS	Android	Raspberry Pi
Browser	Chrome 37+ Firefox 17+ Internet Explorer 9+ SSL requires 11+ or <a href="#SSL">settings change for 9+</a> Edge	Safari 6.0+ SSL requires 7.0+ Chrome 37+ Firefox 17+	Chrome 37+ Firefox 17+	Mobile Safari	Chrome for Android	Raspbian Epiphany Web Browser Chromium for Raspbian Pixel

<a id="Security" name="Security">Security</a>

For <a id="SSL" name="SSL">SSL</a> with IE 9 or 10, you may need manually enable TLSv12 with these steps:

1. Select "Tools" ↠ "Internet Options". Depending on your IE settings, the "Tools" menu may be a gear icon in the upper right hand corner.
2. Go to the "Advanced" tab. 
3. Scroll down to the "Security" section. 
4. Locate and check "Use TLS 1.2" in the Security section.
5. Then, press the "OK" button.

You may need to close and reopen all open browser windows in order for these new settings to take effect.

<a href="http://blog.xojo.com/microsoft-is-killing-internet-explorer-8-9-and-10" target="_blank">Microsoft no longer supplies security updates to IE 9 and 10 for most users</a>, so you may want to consider upgrading to IE 11 or using a different browser.

<a id="Web Server" name="Web Server">Web Server / Deployment</a>

Web apps can be deployed to servers with these requirements:

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):

CPU Compatibility

x86 CPUs require the SSE2 instruction set for the IDE and built applications. The vast majority of desktop CPUs in use support this, but some x86 single board computers may not.

ARM CPUs must support the 32-bit ARMv7 architecture.

<a id="iOS Apps" name="iOS Apps">iOS Apps</a>

In order to work on iOS projects, you must be using Xojo on OS X 10.10 and later with Xcode 7.x or Xcode 8.x (required for iOS Simulator).

<a id="Linux Information" name="Linux Information">Linux Information</a>

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

<thead> </thead> <tbody> </tbody>

Always Required	Required for Desktop	Optional
glib 2.0	GTK+ 2.20	libwebkitgtk-1.0.0 or libgtkhtml (HTMLViewer) Ubuntu install command: sudo apt-get install libwebkitgtk-1.0.0:i386
glibc-2.11 (32-bit) glibc-2.14 (64-bit)		libsoup 2.4 (Xojo.Net.HTTPSocket)
libstdc++.so.6.0.13		GTK+ 2.32 for Picture.Open Horizontal and Vertical resolutions.

<a id="64-bit Configuration" name="64-bit Configuration">64-bit Configuration</a>

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 usually installed by default, so you'll have to install them manually. Below are commands you can use to install necessary libraries for some common Linux distributions:

<tbody> </tbody>

Linux Mint 18 (recommended)	Mint includes most of the necessary libraries. This installs the 32-bit WebKit library so HTMLViewer works: sudo apt-get install libwebkitgtk-1.0:i386
Ubuntu 16.10	This installs the necessary 32-bit libraries: sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libglib2.0-0:i386 libsoup2.4-1:i386 libgtk2.0-0:i386 libwebkitgtk-1.0:i386
openSUSE Leap 42.2	Refer to <a href="https://blog.xojo.com/2016/12/15/livin-la-vida-linux/">this blog post</a>.
Fedora 25	This installs the necessary 32-bit libraries: sudo yum install glib2.i686 libgcc.i686 libstdc++.i686 gtk2.i686 webkitgtk.i686
CentOS 7	This installs the necessary 32-bit libraries: sudo yum install glib2.i686 libgcc.i686 libstdc++.i686 gtk2.i686 Note: 32-bit WebKit does not appear to be available for 64-bit CentOS.

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

<a id="International Components for Unicode" name="International Components for Unicode">International Components for Unicode</a> (libicu)

Linux apps made with Xojo 2016 Release 3 or later include the libicu libraries as part of the app package (in the Libs folder). You do not need to install libicu separately.
