On what platform does this occur?

This other error is unrelated to the original error; there's another issue related to that, please post more details there. Given that the build error is happening on an old distro that's not even supported by the original maintainers anymore, though, it's unlikely I'll spend time addressing it.

I might be able to fix the original issue regarding the fcntl call. Please don't hold your breath, though, as I'm taking a break from open source.

I pushed a fix for the readahead/fnctl issue. Could you please build a new version and confirm it's working?

[dreamsxin]

It's working fine.
