[GHC] #15856: GhostScript not available for hp2ps tests
#15856: GhostScript not available for hp2ps tests -------------------------------------+------------------------------------- Reporter: jrp | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Test Suite | Version: 8.6.1 Keywords: ghostscript | Operating System: Linux gs hp2ps testsuite | Architecture: | Type of failure: Incorrect result Unknown/Multiple | at runtime Test Case: T7919 T14761c | Blocked By: Blocking: | Related Tickets: #15736 Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- When I run `validate --slow` a number of tests fail, apparently erroneously, because `GhostScript not available for hp2ps tests`. I don't know why this is the case (Ghostscript is installed on my ubuntu; perhaps there are some developer libraries / headers that also need to be installed, but I don't recall seeing anything in the documentation about that). The message "GhostScript not available for hp2ps tests" seems to come from a Python script that Simon Marlow produced in 2002. Unfortunately, there are two places where the message could have been generated. There are probably 2 ways forward: - a temporary bodge: taking the running of those tests that depend on hp2ps out of validation, in the same way that certain tests are not run when a dependent library is unavailable - figuring out why the python script fails to understand that a ghostscript is actually present and fixing that -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15856 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Could you check if you see "GhostScript available" after applying it? It seems to me that hasn't been working for some time - I think I fixed GhostScript detection but other things might still be broken. One day, I'd like to simplify the Python runner - currently options are set via `-e`, then `config/ghc`, then `--config`; there are possible conflicts. Ideally, there should be one pass that reads the commandline and sets every option. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15856#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
