I am building my pure haskell LU solver under FreeBSD. I use the -fllvm compiler option because I need extra numerical performance. When I build, I get (this is the output from GitLab CI, which is in turn running 'stack build') {{{ Running with gitlab-runner 11.2.0 (35e8515d) on stacker.18clay.com a2111f63 Using Shell executor...

The compiler is looking for the datalayout for x86_64-unknown-freebsd; but what is available is amd64-portbld-freebsd. Is this just a simple naming error? The stack resolver was the cutting- edge nightly-2018-10-6; if it is a problem in their packaging rather than ghc itself I will file a report with them (though ghc did panic here, and as the breath ebbed from its ASTs and light faded from the code generator, it pleaded that a bug report be filed). I've attached the .cabal file in case it helps. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15718 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I guess I'll just add the missing triplet. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15718#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
