Hi,  
I’m new to Julia and having troubles with the compilation of Singular. was able to add the package but it does not precompile. I am far from beeing a computer expert, so I would really much appreciate your help!  
This is the error message I get when typing “using Singular”:  
[ Info: Regenerating 4ti2 wrappers in /Users/Zineb/.julia/packages/Singular/gc8mN/bin/v1.8  
[ Info: Regenerating /Users/Zineb/.julia/packages/Singular/gc8mN/src/libraryfuncdictionary.jl  
C++ exception while wrapping module libSingular: invalid subtyping in definition of coeffs with supertype Any

I would recommend that you ask questions about Singular.jl and other [OSCAR](https://www.oscar-system.org) packages on the [Oscar Slack](https://www.oscar-system.org/slack), you are much more likely to get a quick answer there. Also, OSCAR itself might be interesting to you as it already contains a lot of functionality for Toric varieties.

Anyway, it seems you are on macOS, which version? And which Julia version (an 1.8 variant – is it 1.8.5?)

Which version of Singular.jl is it? (To find out, check the output of `using Pkg; Pkg.status()`, and perhaps also run `Pkg.update()`)

Do you have any “dangerous” environment variables set like `DYLD_LIBRARY_PATH` ?

I just fixed the problem. It seems that the Singular package was successfully installed, but there was an issue with loading the package due to a C++ exception. I had to update the package Singular.

Thank you however !
