Re: Failure to catch C++ exception in Haskell on OS X

Are we talking about Haskell or linking/ calling c plus plus? If the latter, that’s more of a cabal issue I think? If you mean ghc build wise No. The unwind library only supports elf format. Which OS X does not use. Even that issue aside : ghc currently can’t build with any level of dwarf enabled on OS X, eg the system linker complains about exceeding some system section object format limit. I guess my point is : dwarf data for Haskell libraries on OS X have a few challenges between here and there. On Fri, Jan 4, 2019 at 9:29 PM Bas van Dijk wrote:

A ticket which seems to cover the same problem: https://ghc.haskell.org/trac/ghc/ticket/11829

Wonderful! I can confirm[1] that adding the following to the cabal file fixes the problem:

if os(darwin) ld-options: -Wl,-keep_dwarf_unwind

Shouldn't GHC do this by default when linking on OS X?
