Error: no BLAS/LAPACK library loaded!

This is on Apple M1 processor. The same code works without problems in the same environment on a Mac with Intel processor.

What does this give

julia> using LinearAlgebra

julia> BLAS.get_config()

before and after including the file ?
Are the errors coming from Loraine or CSDP, which solver is used ?

[kocvara]

Both before and after:

julia> BLAS.get_config()
LinearAlgebra.BLAS.LBTConfig
Libraries: 
└ [ LP64] libopenblasp-r0.3.27.dylib

Error getting with any SDP solver.

Also, whenever I try to include again, SumOfSquares is always precompiling again and giving this message

ERROR: LoadError: Failed to precompile SymbolicWedderburn [858aa9a9-4c7c-4c62-b466-2421203962a2] to "/Users/michal/.julia/compiled/v1.10/SymbolicWedderburn/jl_aEU6JV".

[blegat]

Do you get the error simply by doing using SymbolicWedderburn ?

[kocvara]

Ah, ok, all these BLAS errors also come when I just say using SymbolicWedderburn.

[odow]

This happens when you're using libblastrampoline without providing a default BLAS.

This fix is:
https://github.com/jump-dev/Ipopt.jl/blob/4c156461ef1fda3c9f015520197afda4e8ca3e26/src/Ipopt.jl#L14-L19

But it would be useful to know which dependency is causing it.

[kocvara]

It happens right after opening new REPL:

julia> using SymbolicWedderburn
Precompiling SymbolicWedderburn
        Info Given SymbolicWedderburn was explicitly requested, output will be shown live 
Error: no BLAS/LAPACK library loaded!
Error: no BLAS/LAPACK library loaded!
Error: no BLAS/LAPACK library loaded!

[kocvara]

I even removed all other packages from the environment, the problem is still there:

(@v1.10) pkg> st
Status `~/.julia/environments/v1.10/Project.toml`
  [858aa9a9] SymbolicWedderburn v0.4.0

julia> using SymbolicWedderburn

        Info Given SymbolicWedderburn was explicitly requested, output will be shown live 
Error: no BLAS/LAPACK library loaded!
Error: no BLAS/LAPACK library loaded!

[odow]

Then this issue should probably be closed in favor of kalmarek/SymbolicWedderburn.jl#87

[odow]

I've just seen this issue again.

The issue is because @kocvara has only

Libraries: 
└ [ LP64] libopenblasp-r0.3.27.dylib

and some code is probably looking for an ILP blas.

I can't reproduce on an M4:

julia> using LinearAlgebra

julia> BLAS.get_config()
LinearAlgebra.BLAS.LBTConfig

julia> using SumOfSquares

[odow]

I can't reproduce this, even on an M1 machine.

@kocvara how did you install Julia?

If it's not reproducible, I'm tempted to close this issue.
