#11201: ghc --make on Haskell and non-Haskell inputs can silently clobber input -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): Here is a real-life example with an added twist: http://stackoverflow.com/questions/34823628/calling-haskell-from-c -getting-multiple-definition-of-main-linker-error On the one hand, seeing occurrences of this confusing people "in the wild" argues towards doing something; but on the other hand, this particular instance illustrates how it is tricky to do something correct. How do we know whether `inc.o` and `Inc.o` are names that refer to the same file? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11201#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
