Hey all,

 This is on OpenSolaris.  Simple attempts to build cabal packages give me this error, and I don't know what it means.  Here's an example: [07/25 18:51::lally@sol type-level]$ runghc Setup.hs configure Configuring type-level-0.2.4... Setup.hs: fd:8: hGetContents: resource exhausted (Resource temporarily unavailable) Setup.hs: fd:8: resource exhausted

Does anyone know what this means?  I'm trying to just get the llvm bindings installed (requiring mtl & type-level).

A quick guess: you're running out of filedescriptors.

The error gives the descriptor number as 8, so I don't think that's terribly likely :) Resource temporarily unavailable is the string that corresponds to the EAGAIN error, which is typically presented by operations that would block being used in non-blocking mode. I have no idea what would cause it to be a fatal error in a hGetContents call.

I checked that my ulimit was > 8 :-) It was 256, I knocked it up to 65,535, but that didn't help. I've got my own source build of ghc. Is there anything I can put in to track down what's going on? Thanks for all the help folks, -Lally
