Pytanque installation fails on Ubuntu 14.04 about arybo HOT 11 CLOSED

Okay i've got a solution thanks to @romainthomas !
We can install gcc 6.0 and the associated uptodate libstdc++ under Ubuntu 14.04 using a PPA:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get install g++-6

and then install pytanque like this:

$ CC=gcc-6 CXX=g++-6 pip install pytanque

from arybo.

Hello Sebastien,

"pip install pytanque" will install the stable version of pytanque uploaded on Pypi (this one https://pypi.python.org/pypi/pytanque/0.2.0), which should work with the feature/exprs version of Arybo.

The error you have is thus independent of this experimental branch and seems to be related to your Python installation. Which version of Python are you using ? Is this 32-bit or 64-bit ubuntu ?

Thanks :)

Thanks for you quick reply! I'm using Python 2.7.6 on a 64-bit Ubuntu.

Okay ! Can you please try and reproduce this inside a virtualenv :

$ sudo apt-get install virtualenvwrapper
(reload your terminal then)
$ mkvirtualenv arybo-exp
$ workon arybo-expr
(arybo-exp) $ pip install pytanque
(arybo-exp) $ cd /path/to/arybo && python ./setup.py install

from arybo.

I've reproduced the issue in a virtualenv and attached the log of the last command.

Thanks ! This is a much better error message :)
It seems that the GCC compiler on Ubuntu 14.04 is too old and does not support C++14.

One workaround is to install a recent version of Clang using the official LLVM APT repositories here:
http://apt.llvm.org/ .

In a nutshell, add deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty-3.9 main to your /etc/apt/sources.list , then update apt (sudo apt-get update) and install clang-3.9 (sudo apt-get install clang-3.9).

You can then install pytanque using CC=clang-3.9 CXX=clang++-3.9 pip install pytanque .

Let me know if this solves your problem!

Thanks for your suggestion! Unfortunately, it seems that the following symbols are missing in clang-3.9 gets, insert, emplace (see attached error log). Any other suggestions?

Okay the C++ library (listdc++) is also too old... :/
Try and install the packages libc++-dev and libc++abi-dev and relaunch the installation.

I'm sorry I don't have any 14.04 ubuntu VM right now. If this doesn't work, I'll try to find a way tonight (in a few hours) !

Unfortunately, it doesn't work even after installing the two packages you mentioned. Thanks for your help!

from arybo.

Thanks a lot! That worked! Note that you also have to run sudo apt-get update after the first command.

Okay nice :) I'll keep this one open 'till the documentation is updated!
