Usage example does not work

[kockahonza]

Hi, I've just found this package and would love to use it but I'm having trouble getting it to work. I've tried to exact example as in the README and I get "Aborted" for anything besides the simplest things.

julia> using Symbolics; using SymbolicsMathLink

julia> @variables x;

julia> expr = x^2 + x - 1;

julia> result = wcall("Solve", expr==0)
var"\$Aborted"

I think the wolfram installation was found correctly as

julia> wcall("Sin", x)
sin(x)

seems to work as intended, but anything involving Solve fails.

Unfortunately, as far as I can tell that's something going wrong with MathLink, which handles the interface with Mathematica. I'll do some more testing to figure out for sure if that's the case, but if it is that's not easy for me to fix.

I was thinking it might be, thanks for checking though.

It does seem like the issue is in converting the W"Solve" head into Mathematica. I'll try to fix it ASAP.

Finally got around to this, and the mistake was just a typo in the Readme. For Julia Symbolics, the syntax to create an Equation is expr ~ 0 not expr == 0. I've updated the examples in the readme, so give it a try now.
