Installation problem in Ubuntu 12.04

[galfaroi]

This happens at try to $make
I have the rebar function there any clues?

$ make
Getting dependencies ...
/bin/sh: 1: rebar: not found
make: *** [get-deps] Error 127

Thanks

[oubiwann]

Hrm ... you need the rebar executable file. Do you have rebar in your path?

What is the output of "which rebar" -- could you paste that?

I'm not sure if Ubuntu 12.04 had rebar in its apt archives, but if it did
and you installed it that way, you probably want to uninstall it and use
this instead:

$ wget https://github.com/rebar/rebar/wiki/rebar
$ chmod 755 rebar
$ sudo mv rebar /usr/local/bin

Let me know how that goes ...

Hi Duncan,

Thank you for reply. Now I have the following issue.

...
See git-pull(1) for details.

Updating ./deps/py ...

Already up-to-date.
Cleaning ebin dir ...
Compiling project code and dependencies ...
cp: cannot create regular file `./ebin/lsci.app': No such file or directory
make: *** [proj-compile] Error 1

I realized I don't have installed Python 3, that could be the issue?

Thanks

You will defnitely need Python 3 installed, but that's not this particular
issue.

The update shouldn't be happening -- I'll have edit the Makefile to take
that out. But that's an operation that shouldn't err out the make
execution. Actually, the same was true for the first error you reported:
the make execution should have continued and ignored that error.

Hrm, do you have an environment variable set for make? What is the output
of "echo $MAKEFLAGS"? It sounds like you or something you have installed is
giving make the "--stop" parameter. (Many of the make targets for LFE
projects use the "-" before commands to ignore errors and continue to the
best of their ability, usually when the error to be thrown is no bid deal).

Let me know, and I'll also look at things at this end ...

Hrm, it might be an alias set up, too. Perhaps something created an alias
for make that is "make --stop".

To find out, you can do this in bash:

type make

And see what it returns.

Nope. Hadn't gotten to it yet. Just did.

I already installed Python 3 (but I had numpy in 2.7)

To ensure maximum ease of support, lsci expects that you will let it
install a local Python virtual env, per the instructions on the README:

$ make
$ . ./python/.venv/bin/activate

As such, you won't need to use (or worry about affecting) your system
install or already having NumPy, SciPy, etc., set up. (I'm guessing that
was clear, and you were just giving me extra info above... but better to be
safe with more info than sorry with less :-)).

Okay, I did a fresh install myself, and ran into this same issue. I think I
know what it is ... I'll poke around, and send a long an update.

[oubiwann]

Okay, that did it (missing line in one of the make includes; didn't notice
since the ./ebin directory had been created earlier on during project
development).

Thanks for submitting the bug!

Try it again after a git pull --all ...

Hrm, hang on a sec -- don't update yet.

Looks like there's been a ton of work done on ErlPort in the last week or
so (hurray!), but this introduces some breaking changes.

I will update the dependencies so that it pulls from a known good
configuration. You'll need to rm -rf ./deps/erlport and then re-run make.
I'll let you know when.

Okay!

That worked. I needed to pin ErlPort in LFE py (not lsci), so you'll need
to do the following in your lsci cloned dir:

$ rm -rf deps/py deps/erlport
$ make
$ . python/.venv/bin/activate
$ make repl-no-deps

Then, if you don't see errors after starting up, you should be good to go.
Once at the LFE REPL prompt, make sure you can call into Python, e.g.:

(lsci-math:pi)

Sad news, my friend: your distro may be too old for lsci :-(

As far as I'm aware, Ubuntu 12.04 has packages for Python 3.2. The
Python-native venv support didn't land until 3.3. If you can find more
recent Python packages for 12.04 (ideally, Python 3.4), you may be in luck.
Otherwise, you'll need to run with something more modern :-/

Yes, I manually update to Python3.3. pip3 and venv but still the same, I guess this would be the same until I upgrade. Do you think if only use erlport to load a Python function would be the same issue?, I am new to Erlang, I would be awesome to have the same things that Python has (Numpy, Scipy etc). Well... to be honest Elixir is the thing to tookr mr to research this, I see it very haskelian, in a friendlier way..
