Update Readme with new information how to install

[jankatins]

Make installing from the supplied packages the new default and
mention that only IPython 3.1 and above is supported.

Closes: #54 # windows support

[takluyver]

IPython 3.0 does work, as far as I know - the problem you encountered with knitpy only affects other applications starting kernels through the IPython API, not IPython applications. (And it's probably possible to work around, but since 3.1 is already out, I don't think it's worth it).

[takluyver]

Probably? Do we know what happens if you don't?

[jankatins]

I know I have to use it on windows if the repo only has source packages (windows will try binaries first/only and raise something about no packages found if there are no binary packages or the PACKAGE file for binaries is missing). I'm not sure what mac does.

[jankatins]

Anyway: I think the most sensible thing would be to have someone compile the mac packages and install them via drat in that repo...

[takluyver]

On any platforms where we're installing source packages, we will still need to have the ZMQ headers installed, e.g. libzmq3-dev on Debian. Otherwise it won't be possible to compile rzmq.

[jankatins]

Ok, so do we know anybody with with R and a Mac? If so we could include mac packages and the Readme would become "if you are on win/mac, do this, and on linux install the zmq headers and do that." :-)

[flying-sheep]

@noamross from #96 apparently has one :)

[sckott]

i have a mac too - should I test something?

[noamross]

install.packages(c("rzmq","repr","IRkernel","IRdisplay"), repos="http://irkernel.github.io/", type="source") worked for me

[jankatins]

@noamross / @sckott Can you do some package building? Basically checkout all the above packages and then do:

# for g in "rzmq","repr","IRkernel","IRdisplay":
R CMD build %G%
R CMD check %G%_*.tar.gz
R CMD INSTALL --build --compile-both %G%

(Sorry, my bash is rusty, no idea about the loop :-( )

This should produce a lot of *tar.gz (the source packages) and *.tgz (the mac binary packages). The latter could be added to the repo via drat (see here for binary support: eddelbuettel/drat#16)

[noamross]

IRkernel builds, but check gives this error:

* checking package dependencies ... ERROR
Namespace dependencies not required: ‘base64enc’ ‘repr’

IRdisplay and repr give a couple of warnings on check related to naming/documentation. They build fine.

rmzq builds fine when I remember to git clone --recursive.

I have no idea how universal these builds are. I am on OSX 10.10.2.

Where to upload?

[takluyver]

Excellent, thanks. I guess there are a couple of imports we can drop from IRkernel now.

We're just moving towards releasing these packages (#97), so if it's OK, we'll ask you to redo this process in a couple of days with the released versions, and then upload those packages to the repository.

[jankatins]

@noamross Ok, so that works. Would you mind doing a PRs for these files? I will put my drat package somewhere and then you could use that to add your packages to the repo (see #90, which has my initial script to build the R repo: adding to a repo is basically a R --slave -e "drat:::insert('package.tgz', repodir='irkernel.github.io')" with the R which built the package (I use both 3.1 and 3.2)

[takluyver]

Hold off on the PR until we do a release, though - I don't want to make that repo grow ridiculously by adding binaries of unreleased versions.

[flying-sheep]

uh-oh, now this undoes 1a39243. could you change this so it doesn’t?

[jankatins]

@flying-sheep Hopefully i got everything (reduced indention, s/shell/bash/). Not sure if there is more?

[takluyver]

Thanks! If this needs more fixes, we can do them in separate PRs - I'm merging now.

[noamross]

Sure, just ping me when you're ready.
