#15894: Cannot find symbol during interactive linking using new-repl on Windows --------------------------------------+---------------------------- Reporter: YellPika | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.3 Component: Compiler | Version: 8.6.2 Keywords: | Operating System: Windows Architecture: x86_64 (amd64) | Type of failure: Other Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: --------------------------------------+---------------------------- Originally from https://github.com/haskell/cabal/issues/5683. I get the following error on Windows 10: {{{

See top entry above. ByteCodeLink.lookupCE During interactive linking, GHCi couldn't find the following symbol: ieee754zm0zi8zi0zm7eecc33cf22b0ebf4d3c4dda98cc9f039432a266_NumericziIEEE_infinity_closure This may be due to you not asking GHCi to load extra object files, archives or DLLs needed by your current session. Restart GHCi, specifying the missing library using the -L/path/to/object/dir and -lmissinglibname flags, or simply by naming the relevant files on the GHCi command line. Alternatively, this link failure might indicate a bug in GHCi. If you suspect the latter, please send a bug report to: glasgow-haskell-bugs@haskell.org }}} This occurs with both cabal-install 2.4.0.0 and HEAD. This does not occur if I install ieee754 into a sandbox and use `cabal repl`. It also works correctly on Ubuntu 18.04 (on both WSL and a full installation), so it looks like a Windows-specific problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15894 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
