Bug Description

This is new since 9th September. IfcOpenShell has a new rocksdb dependency, I see this error:

That's in the #ifdef USE_MMAP block. I must admit I haven't compiled with that for quite some years. Is that something you rely on?

I don't use it at all, this is for the fedora package where I just enable everything that I can (this also helps shake out bugs like this).

I'll try a build without USE_MMAP

[brunopostle]

(three house later...) yes the build is ok without USE_MMAP.

Thanks for reporting back
