This project is superseded by xs-opam and no longer actively maintained as of 20. March 2017.
To build the xapi-project toolstack components from source:
First install common development tools and headers:
apt-get install build-essential libxen-dev libvirt-dev autoconf m4 blktap-dev libsystemd-dev
For some of the dependencies you may also need to install the following:
apt-get install libssl-ocaml-dev
Second install the opam source package manager.
Initialise an opam configuration and add this repo: (note this will install the OCaml compiler from source, so you don't need to worry about distro package versions)
opam init --comp=4.02.3 eval `opam config env` opam remote add xapi-project git://github.com/xapi-project/opam-repo-dev
To build xapi:
opam depext xapi.xapi-project#master opam install xapi
Testing a code change
If you want to change some library code, then you should recompile all the components that depend on that library -- opam handles this for you automatically.
Consider making a change to stdext. First clone the relevant branch and make your change:
git clone git://github.com/xapi-project/stdext
Next tell opam to use the custom version:
opam remove stdext opam pin add stdext stdext
Next install the component you want to test:
opam install xapi
After making new changes to stdext, it sufficies to:
opam update opam upgrade
How does this relate to [xenserver/buildroot]?
The [xenserver/buildroot] repo creates binary packages of released software, easily installable via a distro's native package manager. These binary packages are intended for users.
Source packages built from this repo are intended for developers: quickly making changes, recompiling and testing.
