I don't know how to do that. And anyway, I don't have access to the machine on which the customer is reporting this. I do believe the report - there is no compilation going on here, they are only running our GHC-compiled binary. They know nothing about GHC (not even that we are using it). I was hoping that there would be some general knowledge about this so I could just pass it on to our customers. But I see everyone else is as surprised as I am about a supposedly static GHC-compiled binary requiring a libgmp.so to run. > Unless this > program is like xmonad and requires ghc behind the scenes to build > something, in which case you would indeed need everything that ghc requires > (and, of course, ghc itself). No definitely not. Erik de Castro Lopo wrote: >>> I suspect the OP's exectuable is already being compiled static. I compiled it static.

Right. Could a dependent library be causing this? For example, this program depends on direct-sqlite, which in turn links to sqlite via FFI. It also depends on wai, which pulls in quite a few indirect dependencies. If so - how would I investigate this and get a complete list of the system libraries that customers are required to install as prerequisites? Jens Petersen wrote: > You built ghc yourself? No. It is the generic Linux binary tarball from GHC HQ. > And ran ldd on $bindir/ghc or $libdir/ghc-version ? No, in $bindir that's just a shell script. It's in $libdir. The executable is ghc; ghc-version is a directory containing object files compiled from libraries.
