checkGhcVersion :: Ghc VersionCheck Source #

Returns True if the run-time version of the ghc package matches the compile-time version For using your own GHC libdir at compile time, inline this logic in your program

compileTimeVersion :: Version Source #

Returns the compile-time version of the ghc package. Uses guessLibdir to find the GHC lib dir

compileTimeVersionFromLibdir :: IO FilePath -> TExpQ Version Source #

Returns the compile-time version of the ghc package given the GHC libdir

runTimeVersion :: Ghc (Maybe Version) Source #

Returns the run-time version of the ghc package by looking up in the package database
