Distribution.Simple.LocalBuildInfo
Description
Once a package has been configured we have resolved conditionals and
dependencies, configured the compiler and other needed external programs.
The LocalBuildInfo is used to hold all this information. It holds the
install dirs, the compiler, the exact package dependencies, the configured
programs, the package database to use and a bunch of miscellaneous configure
flags. It gets saved and reloaded from a file (dist/setup-config). It gets
passed in to very many subsequent build actions.

type InstallDirTemplates = InstallDirs PathTemplate Source #
The installation directories in terms of PathTemplates that contain
variables.
The defaults for most of the directories are relative to each other, in
particular they are all relative to a single prefix. This makes it
convenient for the user to override the default installation directory
by only having to specify --prefix=... rather than overriding each
individually. This is done by allowing $-style variables in the dirs.
These are expanded by textual substitution (see substPathTemplate).
A few of these installation directories are split into two components, the
dir and subdir. The full installation path is formed by combining the two
together with /. The reason for this is compatibility with other Unix
build systems which also support --libdir and --datadir. We would like
users to be able to configure --libdir=/usr/lib64 for example but
because by default we want to support installing multiple versions of
packages and building the same package for multiple compilers we append the
libsubdir to get: /usr/lib64/$libname/$compiler.
An additional complication is the need to support relocatable packages on systems which support such things, like Windows.
data InstallDirs dir Source #
The directories where we will install files for packages.
We have several different directories for different types of files since many systems have conventions whereby different types of files in a package are installed in different directories. This is particularly the case on Unix style systems.

Instances
combineInstallDirs :: (a -> b -> c) -> InstallDirs a -> InstallDirs b -> InstallDirs c Source #
defaultInstallDirs :: CompilerFlavor -> Bool -> Bool -> IO InstallDirTemplates Source #
defaultInstallDirs' :: Bool -> CompilerFlavor -> Bool -> Bool -> IO InstallDirTemplates Source #
substituteInstallDirTemplates :: PathTemplateEnv -> InstallDirTemplates -> InstallDirTemplates Source #
Substitute the install dir templates into each other.
To prevent cyclic substitutions, only some variables are allowed in particular dir templates. If out of scope vars are present, they are not substituted for. Checking for any remaining unsubstituted vars can be done as a subsequent operation.
The reason it is done this way is so that in prefixRelativeInstallDirs we
can replace prefix with the PrefixVar and get resulting
PathTemplates that still have the PrefixVar in them. Doing this makes it
each to check which paths are relative to the $prefix.
