This file specifies what was known about the C compiler at GHC `./configure` time (whether to pass `-no-pie` etc, the path to the C compiler etc). Fortunately, I can override at least some of the entries of the `settings` file, e.g. to use a different GCC than the one GHC got to know about during the `./configure` phase. This is important because is multi-lingual projects, sometimes the build tool for the C++ part of the code wants a special compiler, which GHC should also be using when compiling C. The problem is that I can't override *everything*. If I supply via `-pgmc` a compiler that doesn't understand `-no-pie`, then I can't tell GHC to not pass `-no-pie`. Because I can't supply my own `settings` file, or (equivalently) there exists no CLI flag that allows me to override that particular entry in the `settings` file. What I'd like is something like: {{{ $ ghc -settings /path/to/settings/file }}} that subsumes `-pgmc` and other such flags. I'd be able to tell GHC in one go which compiler I want to use, and what flags GHC should or should not pass to that compiler depending on the features of the compiler. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15319 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Perhaps it would help if we didn't add `-no-pie` to the compiler command line when it has been specified via `-pgmc`? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15319#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

AFAIU from https://ghc.haskell.org/trac/ghc/ticket/7929#comment:2, clearing the compiler flags is already what GHC does for the other flags. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15319#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
