The biggest issue this presents is for users who install and use
OSGeoLive as their desktop as the upgrade path becomes muddled since apt
no longer knows what's installed. Instructions on how to pip upgrade for
end users might help a little.
GOAL: a compelling SciPy / iPython Notebook / matplotlib / IRIS
Specifically for python-scipy, I used
apt-get build-dep python-scipy
to satisfy the math libs dependancies.. I hand-edited the output in
this experiment..
(also adding basic compiler requirements too..) something like this
gfortran gfortran-4.6 html2text libamd2.2.0 libblas-dev libbtf1.1.0
libcamd2.2.0 libccolamd2.7.1 libcholmod1.7.1 libcsparse2.2.3
libcxsparse2.2.3 libklu1.1.0 liblapack-dev libldl2.0.1 libpython3.2
libsuitesparse-dev libumfpack5.4.0 po-debconf python-all python-all-dbg
python-all-dev python-dbg python3-all python3-all-dbg python3-all-dev
python3-dbg python3-dev python3-minimal sharutils swig
NOTE that the current install_iris.sh already uses pip
pip install netCDF4 pyshp
also I used pip install -U pyzmq (seems to be a major component)
I got SciPy 0.13 source and built after the setup.. to see what happens
PROBLEMS:
major python assets are pulled in by other major apps as depndancies,
e.g. python-matplotlib python-numpy etc
So it is unclear what happens if there is a newer pip version in
place already
when the apt requirement is asked for.. apt does not see the existing
install since it
looks at its own record keeping instead of examining the python world..
In some cases (GEOS) the package version goes in /usr/lib while
other installation methods
can put results in /usrlocal/lib .. which is less than ideal but manageable..
I will look into possible clashes a bit, between pip installed
assets and apt installed assets,
to see what really happens.. however, clearly the lesson is the more
up-to-date .debs of
both python and non-python assets we can get, the cleaner this all will be..
One reason this is more than idle inquiry is.. since 12.04 is "old"
the python / iPython / SciPy
has advanced a *lot* while the official apt packages have not changed.
Q. do various Precise-backports repos have different sets of
backports? how different?
> What would really be awesome is something like the cran2deb project
where R package are by script converted into debs so they are always up
to date via apt. So a pypi2deb ppa would be pretty sweet.
This is very much what we need .. as above...
> Also on the Postgis 2.1 topic, all that's needed is to get Ubuntugis to
update their package and all should be good again. Good to know you have
a potential workaround.
honestly, I do not have a complete workaround.. we still need a
PostGIS 2.1 .deb using
libgdal1h
I meant that the apt.postgresql.org repo with PostgreSQL 9.3 is
complete enough to
be a basis for a Pg 9.3 base ..
