Hello. I am interested in the project 'Full fledged calculus module for SymEngine' falling under GSoC 2017. Can someone help me?

@prateeksingh0001, I've no idea why that happens. Can you try cleaning the repo and rebuilding?
@universecoder, that was under GSoC 2016

@isuruf Strange. I am pretty sure it was there until 6 days ago

@isuruf How would I go about 'Implement solvers for SymEngine'
ah no
you'll have to talk with @Sumith1896 for that

@Sumith1896 How would I go about 'Implement solvers for SymEngine' (For GSoC 2017). How should I begin?

@isuruf Regarding symengine/symengine.py#134, how can I check for the SymPy version we are using (and possibly update it)?

@isuruf What is th latest sympy release available? Running conda install sympy install sympy 1.0
Isuru Fernando
@isuruf
Mar 18 2017 16:37
1.0

Can we look at the possibility of installing sympy without conda for travis?
Isuru Fernando
@isuruf
Mar 18 2017 16:45
I think it's better to have symengine's test-suite pass with sympy-1.0
Shikhar Jaiswal
@ShikharJ
Mar 18 2017 16:48
Okay, then the PR will have to be put on hold. There's also a failure in the current builds like here: https://travis-ci.org/ShikharJ/symengine.py/jobs/211715591 , any idea about why cmake is unable to recognise -std=c++11 flag?

@ShikharJ, only run those tests if sympy version > 1.0

@isuruf you missed @universecoder 's question
He wants to implement the solvers for SymEngine (I would be happy to see that :smile: )
Isuru Fernando
@isuruf
Mar 18 2017 17:33
Yes, that's a project proposed by @Sumith1896. I'll let him answer

oh
missed that part before it :smile:

@isuruf The issue is not with the tests. The problem is that the wrapper is unable to recognise that acsch and asech are already implemented in sympy.
Isuru Fernando
@isuruf
Mar 18 2017 18:39
Ah, then use sympy.asech only after checking the sympy version

Thanks! Can you also take a last look here: symengine/symengine.py#131
These are format related changes and hence CI checks are irrelevant.
