Web-based Installation

Web-based installation from Linux is not yet supported.

If you are running Windows, you are in luck. Replacment of your existing Windows installation with Coyotos takes only a few minutes, but be aware that the desktop edition of Coyotos is still a development operating system that is not yet fully complete. Simply click install to run the installer straight from your web browser.

Setting Up A Coyotos Development Environment

The Coyotos tree is approaching the point where intrepid developers can start to experiment with it. For those of you who are curiosity junkies, here is how to go about obtaining it.

Host Operating System

The Coyotos development environment is currently supported on Fedora Core 6, Fedora 7, and Fedora 8. Some users are using other versions of Linux or BSD, but this involves some extra work and we do not actively support it. This page describes how to set yourself up on Fedora Core.

Step one: join the coyotos-dev mailing list. If you want to be notified when the source base is updated, you should also subscribe to the coyotos-commits mailing list.

Installing the Cross Compilers

The first thing to do is to install the RPM package that adds the Coyotos tool repository to your environment. To do this, you should (as root):

rpm -ivh http://www.eros-os.com/YUM/coyotos/fc8/Coyotos-Repository.fc8.noarch.rpm

If you are running Fedora Core 6 or Fedora 7, change the fc8 to either fc6 or fc7, accordingly.

Once this package is installed, you will be able to install the Coyotos cross tools. We currently provide cross compilation kits for IA-32, Coldfire, and ARM/StrongArm targets [the ARM tools are not tested by us, but are actively used by the CapROS team. Depending on your target of interest, you should run one or more of:

yum install coyotos-i386-xenv
yum install coyotos-m68k-xenv
yum install coyotos-arm-xenv

That may take a while. Be patient. The advantage to installing this way is that you will automatically receive updates. Occasionally we have been known to make changes to the source tree that rely on an update in the cross tools. This is happening less and less often over time, but it still happens once in a while.

If we don't supply packaged tools for your platform, the alternative is to build them yourself. Instructions for this can be found here.

Check Out the Source Code

If you don't already have it, you will need to install mercurial. We use mercurial for our source code management. You can find information about how to use mercurial at the mecurial wiki. There is a pre-packaged version of mercurial in the Fedora repository for all recent versions of Fedora. While you are installing mercurial, you may also find the colordiff package useful.

We recommend enabling the Mercurial "fetch" extension. You can do this by creating a file $HOME/.hgrc, and adding:


Checking out the base Coyotos tree can be done with the following command. You may wish to consider doing this within an empty directory:

hg clone http://dev.eros-os.com/hg/coyotos/trunk coyotos

Once you have the main tree checked out, you may also want to consider checking out the tutorial subtree:

cd coyotos/src
hg clone http://dev.eros-os.com/hg/tutorial/trunk tutorial

The other package that is currently available is the ccs-xenv package. It should also be cloned under coyotos/src if you choose to check it out. You don't need it unless you are actively working on the cross tools (e.g. you are porting to a new target or building for a non-Fedora platform).

Building the Tree

With a bit of luck, you should now be able to build the tree with:

cd coyotos/src
./configure i386-unknown-coyotos

Building the Documents

The default build process does not build the documentation tree. If you want that built:

cd coyotos/src
./configure --enable=docs i386-unknown-coyotos

If you have already configured a target platform, it is sufficient to use:

cd coyotos/src
./configure --enable=docs

You can see the current state of your configuration by:

cd coyotos/src

Documentation probably will not build correctly unless you have a live connection to the internet. The culprit is xsltproc, which will be using the connection to fetch the OSDoc DTD from its canonical location. The current release of OSDoc does not provide a good solution to work around this problem. The next release of OSDoc will include an XML catalog file that will allow local access to the DTD.
