Logging error in function dlsym_opt

[MathiasMalandain]

Context

I am working on a tool for automatic generation of FMUs from Python code. Bumping from FMI2 to FMI3, I am using FMI.jl to try to load and simulate the generated FMUs; it really helps me know which FMI3 functions are still lacking from my codebase, so that I can implement them one after the other.

Description

Function fmi3GetBinary is not yet implemented on my side. The check for whether this function exists or not on the FMU's side is not performed with dlsym, but with the tailor-made dlsym_opt function (defined in src/FMI2/ext.jl in my version, moved to src/binary.jl since). This is the source code of this function:

function dlsym_opt(libHandle, symbol)
    addr = dlsym(libHandle, symbol; throw_error=false)
    if addr == nothing
        logWarning(fmu, "This FMU does not support function '$symbol'.")
        addr = Ptr{Cvoid}(C_NULL)
    end
    addr
end

As the program enters the if block, this is indeed the error I get:

ERROR: LoadError: UndefVarError: `fmu` not defined

The code is still exactly the same in the current src/binary.jl file.

Thank you ❤️

Thanks! You are right, we will fix that!
