It appears GHC 7.10.1-rc2 doesn’t support glibc 2.11 — specifically, 2.11.1 (Ubuntu 10.04 LTS) and 2.11.3 (Debian 6). glibc 2.12 (CentOS 6) seems to work fine. Symptoms include:

However, similarly named bindists for GHC 7.8.* work fine with glibc 2.11. In other news, I’m happy to say Halcyon now supports GHC 7.10.1-rc2 on CentOS 6 and 7, Debian 7, Fedora 19, 20, and 21, and Ubuntu 12 and 14. https://halcyon.sh/ $ halcyon install --ghc-version=7.10.1-rc2 --cabal-version=1.22.0.0 Best, -- Miëtek On 2015-01-27, at 00:13, Austin Seipp <aus...@well-typed.com> wrote: > We are pleased to announce the second release candidate for GHC 7.10.1: > > https://downloads.haskell.org/~ghc/7.10.1-rc2/ > > This includes the source tarball and bindists for 64bit/32bit Linux > and Windows.
