Dear all, I am pleased to announce hmpfr-0.3.2, a new version of Aleš Bizjak's bindings to the MPFR arbitrary precision floating point arithmetic library. The changes in this version are quite small but significant: - support for MPFR 3.0.0 as well as MPFR 2.4.* - dependency on integer-simple instead of integer-gmp The latter is most significant because unfortunately it makes it rather more difficult to install hmpfr. Currently almost all binary distributions of ghc have integer-gmp compiled in to provide the Integer type via the standard GMP library. Also haskell platform 2010.2.0.0 assumes that ghc has been compiled with integer-gmp although it makes no specific use of it. Instructions on how to compile ghc and haskell platform with integer-simple instead of integer-gmp are on: http://code.google.com/p/hmpfr/wiki/GHCWithoutGMP The rationale for this change is the fact that despite much effort hmpfr is very unreliable on ghc that includes integer-gmp due to ghc deallocating GMP data that was allocated by MPFR at unpredictable times. Aleš and I hope that hmpfr can return to using integer-gmp once the proposal http://hackage.haskell.org/trac/ghc/wiki/ReplacingGMPNotes#BinaryDropinRepla... to replace gmp with a modified gmp in ghc is implemented and made the default.
