Cant' build/load SymEngine package

New to Julia
,
1

I kind of new in programming. I was following the DifferentialEquations.jl tutorial with the next function:

lv! = @ode_def LotkaVolterra begin
    dx = a*x - b*x*y
    dy = -c*y + d*x*y
end a b c d

I noticed I had to install the ParameterizedFunctions.jl package for using the @ode_def macro. So I installed it and got the following:

Resolving package versions...
  Updating `~/.julia/environments/v1.2/Project.toml`
  [65888b18] + ParameterizedFunctions v4.2.1
  Updating `~/.julia/environments/v1.2/Manifest.toml`
  [65888b18] + ParameterizedFunctions v4.2.1
  [123dc426] + SymEngine v0.7.0

So everything seems to be fine. When I try to execute the code for the LotkaVolterra function I get the following:

LoadError: error compiling #ode_def_opts#1: error compiling symbols: error compiling _symbol: could not load library "libsymengine"
dlopen(libsymengine.dylib, 1): image not found

@ode_def(::LineNumberNode, ::Module, ::Any, ::Any, ::Vararg{Any,N} where N) at macros.jl:11

Then I tried to run ] test ParameterizedFunctions and get the following:

Looking for a solution to this problem, I tried building the SymEngine package with ] build SymEngine and get the following:

I’ve tried other solutions I found, so I really don’t know what else can I do. Any suggestions?

If it is of any use, my configuration is:

Where was this tutorial? I am trying to remove all uses of ParameterizedFunctions.jl in docs and tutorials since its build process is too unruly. Standard usage does not require ParameterizedFunctions.jl

I cant’t find the website but I’m working along with the video tutorial Intro to solving differential equations approximately in 30:00. Thanks in advance.

Oh I see. Yeah, the video is old but it all still is surprisingly up to date after about 2 years? I’d open an issue here https://github.com/symengine/SymEngine.jl/issues to help get this fixed, but it’s not really that big of a deal.

Thanks a lot Chris! How will I know is it has been corrected? Or do I have to test it periodically to see if it works? Sorry for the dumb questions, I really don’t know how those GitHub issues work.

If you post in a Github issue you’ll get a response from the SymEngine developer, and they would close the issue when it’s fixed.
