Build issues

[Sumith1896]

Received a mail today saying the following. I am a bit busy with my end semesters, could somebody check on this? "I am having a lots of problem in installing symengine wrapper for python on a Mac, do you have a guide or something? I have correctly installed the library, or at lest i think, but not the wrapper, i attach the errors:

probably, according with these(http://stackoverflow.com/questions/18565167/non-const-lvalue-references), is a problem of the complier, but i really don’t know haw to solve it, may you kingly help me please? Do you have any solution for these problem?"

This is because of using the latest SymEngine master and Python wrappers don't support that version. There's a file called symengine_version.txt in the root folder with the SymEngine commit supported. This is documented in README.md

Pull request to make the wrappers work with latest SymEngine master is still a work in progress

Thanks @isuruf I have replied to him on the thread. This should be resolved then.

I believe Travis tests this repo on a Mac, so things should work.

Thank you guys, so for what i have understood i should wait for the working version of the wrapper because is not possible find an old version of the library, right?Or maybe I can try to use the Tavis version but I don't know where I can find it.

[isuruf]

While the wrapper is updated you can use the SymEngine version mentioned at https://github.com/symengine/symengine.py/blob/master/symengine_version.txt

After cloning https://github.com/symengine/symengine, do git checkout b5c453f73152dc1b0ec3a39186e5137d48061655 and then install the symengine C++ library.

symengine.py should compile after that

Okok, now it is working, thank you
