Build failed Xubuntu 13.04

[starlocke]

Given a freshly installed Xubuntu 13.04 64-bit Virtualbox Guest, I also experience the following issue: #40

However, no matter which flavour of libreadline-dev I install onto the system, pyenv can't build the python readline extension.

I also face this issue to install python.

@yyuu I would suggest the installer detect first if required libraries are available and tell the user everything that is needed in order to complete the installation.

Here is what you have to install before trying to install python @starlocke
sudo apt-get install libreadline-dev libbz2-dev zlib1g-dev libssl-dev

It might be that you need something else, but those were all for me.

@alfetopito
pyenv even supports Python flavors other than CPython. Because the dependencies are depending on the Python flavor/version to build, checking dependencies is somewhat complicated.

I wrote pyenv-doctor to check dependencies before actual build. It might help this kind of situations.

@alfetopito -- so, you succeeded, using Xubuntu 13.04, 64-bit, fresh install ? If different, please clarify.

PS. I installed all those packages, too, since I read #40 and its solution was those packages (more or less)... still, didn't work for me... thus this report.

I tried to build 2.6.8 on fresh installation of Ubuntu 13.04 Server amd64, and succeeded. I used following script to setup pyenv.

#!/bin/bash -ex
sudo apt-get update
sudo apt-get install -y git build-essential zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev
git clone https://github.com/yyuu/pyenv.git ~/.pyenv
export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
pyenv install -v 2.6.8

@starlocke
Please gist the output of pyenv install -v 2.6.8 2>&1.

build-essential ! I was lacking that debian package. The issue is resolved, but, I'd like to suggest that pyenv reports on missing pre-requisites and quit before going so far as making an attempt at "magic" (building/testing/installing). There's definitely a whole bunch of us who are unfortunately not very savvy with the whole "compile and install from source" methodology, myself included.

Thank you very much, @yyuu, for your awesome contribution to python ease-of-use! 👍 (PS. I don't think you need the output from the above script, at this point, right?)

@starlocke
Yep, you don't need to gist if you succeed to build.

As you written, the missing build dependencies must be the one of most big pitfall for pyenv users. I'd like to improve pyenv doctor command to notice users what is wrong.

[starlocke]

I haven't tried pyenv doctor, but I'm sure it deserves a mention in the pyenv main project's README.md 😄

[alfetopito]

Mine worked only with those libraries I mentioned because I didn't notice that build-essential was installed by other package.

@yyuu I didn't know about pyenv doctor, thanks for pointing it out.
And I agree with @starlocke that a mention on README would help us all on this.
