Chapter 4. Installation Walk-through

This section assumes you have started the installer as described in either Section 3.1, “Installation on Linux” or Section 3.2, “Installation on Windows”. While root access on Linux is no longer a requirement, you must be logged on as Administrator or a user with Administrator privileges on Windows.

If the eCosPro Developer's Kit is already installed on the host, you will receive a warning pop-up and be asked if you wish to re-install, overwriting any previous installation. For further details of reinstalling components, please read Chapter 9, Reinstalling Components.

Figure 4.1, “eCosPro Installer Introduction Screen” illustrates the first window, the introduction window, of the eCosPro GUI install process.

Figure 4.1. eCosPro Installer Introduction Screen

The software provided in the eCosPro Developer's Kit falls under a number of different licenses. The dialog box illustrated in Figure 4.2, “License Agreement Screen” allows you to read these licenses, also available online at http://www.ecoscentric.com/licensing/ecospro-distribution-licenses.shtml. The installer will not allow you to continue with the installation until you agree to adhere and abide by all of the terms and conditions of all of the licenses. If you agree, select the option marked “I accept the agreement” and press “Next”. You will then proceed to the screen described in Section 4.3, “Select Components”.

Figure 4.2. License Agreement Screen

If you do not agree, select the option marked “I do not accept the agreement” and select “Next”. A pop-up will confirm you wish to exit the installation.

Note

By selecting “Next” you are entering into binding legal agreements between yourself and the licensors of the software being provided to you. Please ensure you are able to comply with the terms and conditions of the licenses before accepting them and understand the penalties of failing to adhere to the licenses. A set of guidelines to follow when releasing products that incorporate software from an eCosPro release may be found at http://www.ecoscentric.com/licensing/license-compliance-guide.shtml

The eCosPro Developer's Kit is made up primarily of four different components, each with its own installer:

Figure 4.3. Select Components

The component selection frame allows you to determine which components or items, along with their default sub-component selections, are to be installed. Naturally, the default sub-components differ between installers. For example:

Normally you would leave all components selected as illustrated in Figure 4.3, “Select Components” and select “Next”.

	Warning
	If you de-select a component, not all parts of the eCosPro developer's kit may function correctly. In this case you are advised to create your own development profile or environment, selecting your own eCosPro host tools, GNU Tools or Eclipse as you require. Please read the section on Profiles in the eCosPro User's Guide for further information on eCospro Profiles.

By default, each component is installed into a separate subdirectory within a main eCosPro installation directory, also known as the base directory. This location may be changed in the frame illustrated in Figure 4.4, “eCosPro component base directory screen”. The default location of this main installation sub-directory is as follows:

For example, eCosPro 4.1.3 will be installed into C:\eCosPro\ecos-4.1.3 on Windows and $HOME/ecospro/ecos-4.1.3 as a regular Linux user.

Figure 4.4. eCosPro component base directory screen

This frame, illustrated in Figure 4.4, “eCosPro component base directory screen”, allows you to select the base directory into which eCosPro components are to be installed by default. Once set, this is used as the parent directory for all subsequent automated eCosPro installations by the primary installer. You will not be shown this frame again.

If you wish to choose a different location for the base directory, select the folder icon called out in Figure 4.4, “eCosPro component base directory screen” to create or browse to the base directory, or simply enter the path to the base directory in the field provided.

Once you have selected or confirmed the base directory, press “Next” to select the installation directory for the curent component.

	Warning
	Do not select an alternative location that contains spaces within any part of the path or the folder name. Spaces cause issues with the GNU Tools, in particular GNU make which uses spaces as separators and is used to build eCosPro and its applications.

The next step of the installation process is to select where you wish to install the eCosPro component, as illustrated in Figure 4.5, “Installation Location Screen”.

Figure 4.5. Installation Location Screen

If you wish to install to a different location, select the folder icon called out in Figure 4.5, “Installation Location Screen” to create or browse to folder into which the component is to be installed, or simply enter the path to the installation directory in the field provided.

Once you have selected or confirmed the installation folder, press “Next”.

	Warning
	Do not select an alternative location that contains spaces within any part of the path or the folder name. Spaces cause issues with the GNU Tools, in particular GNU make which uses spaces as separators and is used to build eCosPro and its applications.

To continue the installation you must have internet access available as well as the username and password used to access the eCosPro developer's kit portal at https://www.ecoscentric.com/cgi/nph-epdk.cgi.

Some corporations only permit access to the internet through proxy servers, some of which also require authentication. If you do not require the use of a proxy server, ensure the box illustrated in Figure 4.6, “Connection Information Screen” is not selected and press “Next”. If you require the use of a proxy server, check the box illustrated in Figure 4.6, “Connection Information Screen”, press “Next”, enter the proxy information as illustrated in Figure 4.7, “Proxy Configuration Screen”, and press “Next”.

Figure 4.6. Connection Information Screen

Figure 4.7. Proxy Configuration Screen

Provide the username and password used to access the eCosPro developer's kit portal, illustrated in Figure 4.8, “Connection Information Screen”.

Figure 4.8. Connection Information Screen

When complete, press “Next” for the installer to fetch the licenses applicable to you and to proceed to the next frame. If you are not licensed for an eCosPro component selected for installation, the installer will display an error message and exit.

The summary page displays the components you have selected for installation, the installation location, as well as the licensee information. This includes the name and address of your company and any other details relevant to your license. Please review the information provided and click “Next” to proceed with the installation.

Figure 4.9. Summary Screen

If you do not satisfy the constraints, click on the Cancel button followed by the YES button of the following pop-up window in order to cancel the installation, and contact eCosCentric.

The eCosPro installer will commence with the installation of the components selected as illustrated in Figure 4.10, “Component Installation Screen”.

Figure 4.10. Component Installation Screen

The primary and Eclipse installers invoke various processes and other installers. As a result, various pop-up windows executing commands and providing the status and progress of the installation will also appear as illustrated in Figure 4.11, “Multiple Installation Screens”

	Warning
	Do not close or interact with these pop-up windows. They will close when the command completes or the external component installer finishes.

Figure 4.11. Multiple Installation Screens

If an error occurs, such as the error illustrated in Figure 4.12, “Missing Java Error Dialog”, you will be prompted whether you wish to continue the installation, ignoring the error or failure, or whether you wish to cancel the installation. If you cancel the installation, components successfully installed by the primary installer will not be uninstalled. Only partial installations will be removed.

Figure 4.12. Missing Java Error Dialog

While every attempt to avoid the use of shared libraries on Linux has been made through the static linking of libraries, the advance of Linux distributions has resulted in the change of format and location of shared files (for example, wxGTK 2.8.18, used by the eCos GUI Configuration tool, is the most commonly affected through its use of common icons). In the wxGTK example, the native shared library libpng12.so is used to prevent such problems arising. The Host Tools installer therefore runs basic checks to determine missing shared libraries and provide a warning dialog if any are detected. If run individually, the Host Tools installer will provide the user the opportunity to install the dependancy and re-test. Otherwise it will continue installation and warn the user towards the end of the installation of the missing shared library. Missing shared libraries must be installed for the tools to run: please use your native package manager to determine which package provides these shared libraries and install them.

When the installation has completed, a frame such as the one illustrated in Figure 4.13, “Setup Complete Screen” is shown. At this point, if there are any documented notes or issues specific to this release, they will be contained in a README file which you can optionally display by selecting the checkbox, before selecting “Finish”. This file is also located at the root installation directory.

The installer will terminate when the README window is closed. If the README is not selected, it will terminate immediately.

	Important
	The documentation index includes links to the documentation of the target platforms for which the eCosPro release was made. This documentation will describe how to set up your embedded hardware for eCosPro development and, if applicable, how to install RedBoot, GDB Stubs and how to debug your application using JTAG. Please ensure you read through this target platform documentation thoroughly.

Figure 4.13. Setup Complete Screen

While eCos and eCosPro releases are provided in source code format, the source code of the eCosPro Host Tools and the GNU Toolchains, can also be installed. To install these you must run each of the eCosPro Host Tools and the GNU Toolchain installers separately from the primary eCosPro installer, ideally prior to running the primary eCosPro installer. The source code will be installed in the src subdirectory of each component. For example, on Linux hosts:

On Windows hosts:

The source code to the Eclipse IDE is not provided.

Notes

You do not need to install the source code for either the eCosPro Host Tools or the GNU Toolchains in order to develop and build eCosPro and eCosPro applications. They are only needed if you wish to re-build the host executables for the eCosPro Host Tools or GNU Toolchains. They may also be installed at a later stage by re-running the individual installer for the relevant component (see Chapter 9, Reinstalling Components). The eCosPro primary installer will not attempt to install a component if it has already been installed. It will not install the source code for the eCosPro Host Tools or the GNU Toolchains.

	Important
	The standard eCosPro support contracts provided by eCosCentric do not include support for rebuilding the host and GNU tools.

The Eclipse instllation requires a Java Runtime Environment (JRE) with a minimum version on 1.8 to be installed on your host system in order to run. This must be installed prior to installing the eCosPro CDT plugin for Eclipse. The Eclipse installer will attempt to locate a JRE on the host system during installation. If it fails to find a suitable candidate, it terminate with an error as illustrated in Figure 4.12, “Missing Java Error Dialog”.

By default, the standard Eclipse CDT installation for your host is installed by the installer, and the eCosPro CDT plugin for Eclipse installed within this installation using the Eclipse p2 installer. If you wish to install the eCosPro CDT plugin for Eclipse into a third-party or existing release of Eclipse, you must run the eCosPro Eclipse installer separately and deselect the Eclipse component. You will still be prompted for the location where Eclipse is to be installed - this is for the location of the accompanying documentation. However, when you progress to the next frame you will also be prompted to provide the path to the eclipse executable for the Eclipse installation into which the plugin is to be installed. The eCosPro CDT plugin for Eclipse installer will then invoke that installation's p2 installer to install the plugin.

	Warning
	Eclipse does not attempt to check whether a JRE or a suitable JRE is installed following its installation. Eclipse will simply fail to start if no JRE is found or will terminate with an error if the first JRE found in its path is unsuitable.

In general, we recommend installing eCosPro from within your graphical desktop environment (GNOME or KDE), but installation is also possible from a text-only console or remote shell, as illustrated in Figure 4.14, “eCosPro Linux Console Installation”. The installation steps are very similar to the graphical installation, with the primary installer spawning the installers of dependent components if they are not already installed. To perform a console installation, run the primary installer with the additional parameters --mode text. Component installers may also be individually executed if you are upgrading specific components of the eCosPro Developer's Kit.

	Note
	The Console installation method is not available for Windows hosts.

Advanced eCosPro users may wish to install eCosPro or its components individually. When doing so users must then set their own build environment to configure and build eCosPro and their applications. For example, the PATH environment variable must be set to include the bin directory of the GNU Toolchain at its installed location (e.g. /opt/ecospro/gnutools-arm-eabi-4.7.3j/bin or C:\eCosPro\gnutools-arm-eabi-4.7.3j\bin) as well as the bin directory of the eCos host tools at their installed location (e.g. /opt/ecospro/ecoshosttools-4.0.2/bin or C:\eCosPro\ecoshosttools-4.0.2\bin). They must also set the ECOS_REPOSITORY environment variable to point to the packages subdirectory of the eCosPro installation (e.g. /opt/ecospro/ecos-4.1.3/packages or C:\eCosPro\ecos-4.1.3\packages). For further information please see Chapter 6, Environment Variables.
