Modules/Setup - platform/external/python/cpython3 - Gitiles

 # -*- makefile -*-
 # The file Setup is used by the makesetup script to construct the files
 # Makefile and config.c, from Makefile.pre and config.c.in,
 # respectively.  Note that Makefile.pre is created from Makefile.pre.in
 # by the toplevel configure script.

 # (VPATH notes: Setup and Makefile.pre are in the build directory, as
 # are Makefile and config.c; the *.in files are in the source directory.)

 # Each line in this file describes one or more optional modules.
 # Modules configured here will not be compiled by the setup.py script,
 # so the file can be used to override setup.py's behavior.
 # Tag lines containing just the word "*static*", "*shared*" or "*disabled*"
 # (without the quotes but with the stars) are used to tag the following module
 # descriptions. Tag lines may alternate throughout this file.  Modules are
 # built statically when they are preceded by a "*static*" tag line or when
 # there is no tag line between the start of the file and the module
 # description.  Modules are built as a shared library when they are preceded by
 # a "*shared*" tag line.  Modules are not built at all, not by the Makefile,
 # nor by the setup.py script, when they are preceded by a "*disabled*" tag
 # line.

 # Lines have the following structure:
 #
 # <module> ... [<sourcefile> ...] [<cpparg> ...] [<library> ...]
 #
 # <sourcefile> is anything ending in .c (.C, .cc, .c++ are C++ files)
 # <cpparg> is anything starting with -I, -D, -U or -C
 # <library> is anything ending in .a or beginning with -l or -L
 # <module> is anything else but should be a valid Python
 # identifier (letters, digits, underscores, beginning with non-digit)
 #
 # (As the makesetup script changes, it may recognize some other
 # arguments as well, e.g. *.so and *.sl as libraries.  See the big
 # case statement in the makesetup script.)
 #
 # Lines can also have the form
 #
 # <name> = <value>
 #
 # which defines a Make variable definition inserted into Makefile.in
 #
 # The build process works like this:
 #
 # 1. Build all modules that are declared as static in Modules/Setup,
 #    combine them into libpythonxy.a, combine that into python.
 # 2. Build all modules that are listed as shared in Modules/Setup.
 # 3. Invoke setup.py. That builds all modules that
 #    a) are not builtin, and
 #    b) are not listed in Modules/Setup, and
 #    c) can be build on the target
 #
 # Therefore, modules declared to be shared will not be
 # included in the config.c file, nor in the list of objects to be
 # added to the library archive, and their linker options won't be
 # added to the linker options. Rules to create their .o files and
 # their shared libraries will still be added to the Makefile, and
 # their names will be collected in the Make variable SHAREDMODS.  This
 # is used to build modules as shared libraries.  (They can be
 # installed using "make sharedinstall", which is implied by the
 # toplevel "make install" target.)  (For compatibility,
 # *noconfig* has the same effect as *shared*.)
 #
 # NOTE: As a standard policy, as many modules as can be supported by a
 # platform should be present.  The distribution comes with all modules
 # enabled that are supported by most platforms and don't require you
 # to ftp sources from elsewhere.
