[sage-devel] Trying to fix trac #18488(solve() ignores conjugate)

[Utkarsh Sharma]

I recently came across https://trac.sagemath.org/ticket/18488 and I wanted 
to try fixing the issue. After going through past discussions and the 
solve() method in src/sage/symbolic/relation(which, I believe, is the 
solve() method being referred to here), I figured out that it uses maxima's 
solve() method, so the bug must be in maxima's solve() method.

So how do I go about solving this issue? one obvious solution would be to 
fix the maxima bug, but is there anything else that can be done? I think 
first we could check whether the bug is being encountered or not, and if it 
was encountered, We could provide an alternate solution, like solving for 
the real and imaginary parts separately, or maybe solving for the conjugate 
and then take the conjugate of both sides of the equation. Those are just 
my initial thoughts, I thought it would be best to start a conversation 
here before going any further.

[sage-devel] Re: Error building from source

[Utkarsh Sharma]

Never mind, I tried uninstalling the singular I had downloaded from 
homebrew and ran make again, and sage installed it as an spkg. Now Sage 
works fine on my computer.
