Hello everyone,

I'm trying to "pip3 install" or "python3 setup-install" the python client module pyindi-client on a ubuntu 16.04 LTS machine, but I get an error:

/usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support #for the ISO C++ 2011 standard. This support must be enabled #with the -std=c++11 or -std=gnu++11 compiler options.

cf full log included below.

Indeed, I can solve the error by introducing "-std=c++11" in the compiler. When done, the gcc creates a .o in the ad hoc build/. without any error!
But, I restart the setup.py install, the process is done over again without skiping existing .o, so I need to find where to put this compiler option within the
pyindi-client-0.2.1 distrib. Do you know that?

Any help would be greatly appreciated!

OK, I answer my own topic, because I found a solution in the forum... after a fair number of hours.

The answer to how do I add a compilation option to an existing distribution of pyindi-client is, go in setup.py file and edit the section (red color edit):

pyindi_module = Extension('_PyIndi',
sources=,
language='c++',
extra_compile_args=[ '-std=c++11'],
extra_objects = [join(libindipath, 'libindiclient.a')]

That worked perfectly in my case.

Cheers,

Remi

Hi Rémi,
Thanks for reporting (and for giving the answer), I don't rebuild the package very often.
I just made the update on pypy.org (version 0.2.2).
Jean-Luc.
