|
2 # The file Setup is used by the makesetup script to construct the files |
|
3 # Makefile and config.c, from Makefile.pre and config.c.in, |
|
4 # respectively. The file Setup itself is initially copied from |
|
5 # Setup.dist; once it exists it will not be overwritten, so you can edit |
|
6 # Setup to your heart's content. Note that Makefile.pre is created |
|
7 # from Makefile.pre.in by the toplevel configure script. |
|
8 |
|
9 # (VPATH notes: Setup and Makefile.pre are in the build directory, as |
|
10 # are Makefile and config.c; the *.in and *.dist files are in the source |
|
11 # directory.) |
|
12 |
|
13 # Each line in this file describes one or more optional modules. |
|
14 # Modules enabled here will not be compiled by the setup.py script, |
|
15 # so the file can be used to override setup.py's behavior. |
|
16 |
|
17 # Lines have the following structure: |
|
18 # |
|
19 # <module> ... [<sourcefile> ...] [<cpparg> ...] [<library> ...] |
|
20 # |
|
21 # <sourcefile> is anything ending in .c (.C, .cc, .c++ are C++ files) |
|
22 # <cpparg> is anything starting with -I, -D, -U or -C |
|
23 # <library> is anything ending in .a or beginning with -l or -L |
|
24 # <module> is anything else but should be a valid Python |
|
25 # identifier (letters, digits, underscores, beginning with non-digit) |
|
26 # |
|
27 # (As the makesetup script changes, it may recognize some other |
|
28 # arguments as well, e.g. *.so and *.sl as libraries. See the big |
|
29 # case statement in the makesetup script.) |
|
30 # |
|
31 # Lines can also have the form |
|
32 # |
|
33 # <name> = <value> |
|
34 # |
|
35 # which defines a Make variable definition inserted into Makefile.in |
|
36 # |
|
37 # Finally, if a line contains just the word "*shared*" (without the |
|
38 # quotes but with the stars), then the following modules will not be |
|
39 # built statically. The build process works like this: |
|
40 # |
|
41 # 1. Build all modules that are declared as static in Modules/Setup, |
|
42 # combine them into libpythonxy.a, combine that into python. |
|
43 # 2. Build all modules that are listed as shared in Modules/Setup. |
|
44 # 3. Invoke setup.py. That builds all modules that |
|
45 # a) are not builtin, and |
|
46 # b) are not listed in Modules/Setup, and |
|
47 # c) can be build on the target |
|
48 # |
|
49 # Therefore, modules declared to be shared will not be |
|
50 # included in the config.c file, nor in the list of objects to be |
|
51 # added to the library archive, and their linker options won't be |
|
52 # added to the linker options. Rules to create their .o files and |
|
53 # their shared libraries will still be added to the Makefile, and |
|
54 # their names will be collected in the Make variable SHAREDMODS. This |
|
55 # is used to build modules as shared libraries. (They can be |
|
56 # installed using "make sharedinstall", which is implied by the |
|
57 # toplevel "make install" target.) (For compatibility, |
|
58 # *noconfig* has the same effect as *shared*.) |
|
59 # |
|
60 # In addition, *static* explicitly declares the following modules to |
|
61 # be static. Lines containing "*static*" and "*shared*" may thus |
|
62 # alternate throughout this file. |
|
63 |
|
64 # NOTE: As a standard policy, as many modules as can be supported by a |
|
65 # platform should be present. The distribution comes with all modules |
