The Glorious Glasgow Haskell Compilation System, version 7.10.1- description updated
The problem is that ssh isn't specifying bounds on the 'process' library, and ssh-0.2.11 doesn't compile with the latest process. ssh-0.3 fixes the compile problem, but specifies bounds on other libraries that prevent it compiling with GHC 7.10.
Also, don't use ssh 0.2.11 as it has a serious security flaw: http://joyful.com/blog/2015-04-20-ssh-darcs-hub-vulnerability.html
The GHC 7.10 dependencies are fixed in the source repository, just waiting on one fix to a test-only dependency. If that's not forthcoming soon I'll work around it anyway.
Separate to this I need to go back and fix all the version bounds on old and current versions so that cabal doesn't try to build with unsupported dependencies.
- status set to closed
ssh 0.3.1 has been uploaded now and should work with GHC 7.10
