PMR2 base system build instructions for Gentoo

Start the process by either following the base_image build instructions or start from a clone of it.

The following instructions assumes the usage of the root user account.

System level prerequisites

As the man portage tree no longer has the ebuilds for virutoso, and that it is easier just to have this available as a system level dependency, create a portage repository configuration with the following contents at /etc/portage/repos.conf/pmr2-overlay.conf:

[pmr2-overlay]
location = /usr/local/portage/pmr2-overlay
sync-type = git
sync-uri = https://github.com/PMR2/portage.git
priority = 50
auto-sync = Yes

Emerge sync the repo (ensure that dev-vcs/git was already installed) and then

# emerge --sync pmr2-overlay

There are various system level dependencies required for the full build to succeed.

Plone uses the 'Pillow' image library, following are required

media-libs/libjpeg-turbo
the minimum required package.
media-libs/openjpeg
extra package for the jpeg2k support, which also depends on other image libraries that Pillow can use (e.g. png)

For pygit2

dev-python/cffi
the bindings to libgit2 require this

For virtuoso

dev-db/virtuoso-server::pmr2-overlay
the base server.
dev-db/virtuoso-odbc::pmr2-overlay
the virtuoso unix odbc driver
dev-db/unixODBC
provides the actual implementation for the unix odbc.

For CellML API

dev-util/cmake
cmake is the build system
net-misc/omniORB
needed to turn the .idl interface files into .hxx c++ header files.

For build environment isolation

dev-python/virtualenv
for setting up a python virtualenv.

Install the various system level dependencies as specified above so that the buildout command will work for PMR.

# emerge --ask net-misc/omniORB dev-util/cmake dev-db/unixODBC \
    dev-python/cffi media-libs/openjpeg media-libs/libjpeg-turbo \
    dev-python/virtualenv \
    dev-db/virtuoso-odbc::pmr2-overlay \
    dev-db/virtuoso-server::pmr2-overlay

Also ensure that python2 is activated for the duration of the build. This is to ensure that the various naive build scripts that make use of system Python with Python 2 syntax.

# eselect python set python2.7

Installation of the PMR2 application stack.

Need to have zope user added and switch to that for the application stack.

# useradd -m -k /etc/skel zope
# su - zope
$ cd ~

Continue with the build process as the zope user.

Clone the repository and build it normally. As Mercurial support is no longer needed on production, consider using the buildout-git.cfg

$ git clone https://github.com/PMR2/pmr2.buildout
$ cd pmr2.buildout
$ python bootstrap.py
$ bin/buildout -c buildout-git.cfg
