#11748: GHC runtime linker: fatal error: I found a duplicate definition for symbol -------------------------------------+------------------------------------- Reporter: jeiea | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 (Linking) | Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 Type of failure: Compile-time | (amd64) crash | Test Case: Blocked By: | Blocking: Related Tickets: #11223 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jeiea): It is simplified drastically. I found just using foreign imported rgb function from other package emits same error. But I don't know whether its cause is same to original project. {{{
