simpleGhcEnvironmentFile :: PackageDBStack -> [UnitId] -> [GhcEnvironmentFileEntry]

Make entries for a GHC environment file based on a PackageDBStack and a bunch of package (unit) ids.

If you need to do anything more complicated then either use this as a basis and add more entries, or just make all the entries directly.

renderGhcEnvironmentFile :: [GhcEnvironmentFileEntry] -> String

Render a bunch of GHC environment file entries

writeGhcEnvironmentFile

Arguments

:: FilePath

directory in which to put it

-> Platform

the GHC target platform

-> Version

the GHC version

-> [GhcEnvironmentFileEntry]

the content

-> IO FilePath

Write a .ghc.environment-$arch-$os-$ver file in the given directory.

The Platform and GHC Version are needed as part of the file name.

Returns the name of the file written.

ghcPlatformAndVersionString :: Platform -> Version -> String

GHC's rendering of its platform and compiler version string as used in certain file locations (such as user package db location). For example x86_64-linux-7.10.4

Version-specific implementation quirks

getImplInfo :: Compiler -> GhcImplInfo

data GhcImplInfo

Information about features and quirks of a GHC-based implementation.

Compiler flavors based on GHC behave similarly enough that some of the support code for them is shared. Every implementation has its own peculiarities, that may or may not be a direct result of the underlying GHC version. This record keeps track of these differences.

All shared code (i.e. everything not in the Distribution.Simple.FLAVOR module) should use implementation info rather than version numbers to test for supported features.
