4 | Description of Guile's public config header mechanics: | |
5 | ----------------------------------------------------- | |
6 | ||
7 | Guile has four core headers: | |
8 | ||
9 | config.h: Guile's private automatically generated configuration | |
10 | header -- generated by configure.in and autoheader. *NOT* | |
11 | installed during "make install" and so may not be referred to by | |
12 | any public headers. | |
13 | ||
14 | libguile/_scm.h: Guile's private core header. _scm.h is not | |
15 | installed. It's only visible to the libguile sources | |
16 | themselves, and it includes config.h, the private config header. | |
17 | Among other things this file provides a place to make decisions | |
18 | based on the information gathered in config.h. | |
19 | ||
20 | libguile/scmconfig.h: Guile's public automatically generated | |
21 | configuration header -- generated at build time by concatenating | |
22 | the contents of libguile/scmconfig.h.top with the output from | |
23 | libguile/gen-scmconfig. gen-scmconfig bases its output on the | |
24 | information in the private config.h header, the contents of | |
25 | gen-scmconfig.h (which is created by configure.in from | |
26 | gen-scmconfig.h.in), and the information provided in this file, | |
27 | gen-scmconfig.c. | |
28 | ||
29 | libguile/__scm.h: Guile's public core header. This file is | |
30 | installed and publically visible. It includes | |
31 | libguile/scmconfig.h, the public config header and provides a | |
32 | place to make decisions based on the information gathered in | |
33 | scmconfig.h to define things that other headers can depend on. | |
34 | ||
35 | Notes and guidelines: | |
36 | ||
005f04cd RB |
37 | - use 1 and 0 for public #defines instead of "def and undef", |
38 | i.e. use #define SCM_HAVE_FOO rather than just not defining | |
39 | SCM_HAVE_FOO whenever possible. See GNU Coding Guidelines for | |
40 | rationale. The only notable non-deprecated exceptions to this | |
41 | rule are GUILE_DEBUG and GUILE_DEBUG_FREELIST which do not follow | |
42 | this convention in order to retain backward compatibility. | |
43 | ||
caeef9cb RB |
44 | - in the code below, be *VERY* careful not to use or rely on any |
45 | runtime-dynamic information below. For example, you cannot use | |
46 | sizeof (FOO), but must use static information like SIZEOF_BAR | |
47 | (from config.h) or SCM_SIZEOF_BAZ (from scmconfig.h). This is | |
48 | because the gcc that is compiling gen-scmconfig.c and/or the | |
49 | machine that is running gen-scmconfig may not be the same | |
50 | compiler and/or hardware that will eventually be running Guile. | |
51 | (i.e. keep the cross-compilation case in mind). | |
52 | ||
53 | - try to avoid adding names to the public namespace when possible. | |
54 | Note in the code below, that in a number of cases, we detect a | |
55 | feature and based on that, we decide whether or not to print | |
56 | anything at all. This decreases the extraneous #defines and | |
57 | #ifdefery that we require in scmconfig.h | |
58 | ||
59 | - try to avoid adding any duplicate definitions to config.h and | |
60 | scmconfig.h. i.e. have just SCM_ENABLE_ELISP in scmconfig.h | |
61 | rather than ENABLE_ELISP in config.h and SCM_ENABLE_ELISP in | |
62 | scmconfig.h. | |
63 | ||
64 | - in cases where you need to communicate information from | |
65 | configure.in to gen-scmconfig.c, don't add an AC_DEFINE unless | |
66 | you need it for other purposes. Just add a suitable SCM_I_GSC_* | |
67 | variable to configure.in, set the value, AC_SUBST the value, and | |
68 | add an appropriate line to gen-scmconfig.h.in. All gen-scmconfig | |
69 | related AC_SUBST vars should be prefixed with SCM_I_GSC_. | |
70 | ||
71 | - make sure that anything that we explicitly typedef publically is | |
72 | prefixed with scm_t_. i.e. we used to typedef long to ptrdiff_t | |
73 | if we didn't detect ptrdiff_t, but this has been changed so that | |
74 | we typedef scm_t_ptrdiff instead so that we won't conflict with | |
75 | any non-guile header definitions of the same type. For types | |
76 | like intptr_t and uintptr_t which we just try to detect and don't | |
77 | actually define, it's fine not to have a corresponding scm_t_ | |
78 | type. | |
79 | ||
80 | - we now use SCM_SIZEOF_FOO != 0 rather than SCM_HAVE_FOO for any | |
81 | cases where the size might actually vary. For types where the | |
82 | size is fixed, we use SCM_HAVE_FOO, i.e. you can see us define or | |
83 | not define SCM_HAVE_T_INT64 below when appropriate. | |
84 | ||
85 | Rationales (not finished): | |
86 | ||
87 | Why do we use a C program here rather than AC_OUTPUT_COMMANDS? | |
88 | -------------------------------------------------------------- | |
89 | ||
90 | The main reason is that there are some values we would need | |
91 | access to at AC_OUTPUT_COMMANDs that are determined by configure | |
92 | but are not available at AC_OUTPUT time. The values are *only* | |
93 | available via config.h. We use gen-scmconfig so we can see those | |
94 | values and make decisions based on their settings. | |
95 | ||
96 | Why have gen-scmconfig.h.in? | |
97 | ---------------------------- | |
98 | ||
99 | Without that header, we could end up needing multiple aliases for | |
100 | public settings like SCM_ENABLE_ELISP. We can't define | |
101 | SCM_ENABLE_ELISP in config.h since that header is private and any | |
102 | definition in scmconfig.h would conflict (#ifndef might be | |
103 | possible but runs the risk of conflicting directives), so a | |
104 | likely solution would be to AC_DEFINE([SCM_I_ENABLE_ELISP]), and | |
105 | then use SCM_I_ENABLE_ELISP in gen-scmconfig via config.h to | |
106 | determine whether or not to #define SCM_ENABLE_ELISP, but this | |
107 | leaves us with two #defined symbols for each public setting -- | |
108 | better to just have one value (public or private) that all code | |
109 | uses. | |
110 | ||
111 | Having this header means we can AC_SUBST a value like | |
112 | SCM_I_GSC_ENABLE_ELISP and then set it in here via AC_OUTPUT | |
113 | substitutions, and gen-scmconfig can use that definition to | |
114 | determine whether or not to #define SCM_ENABLE_ELISP when | |
115 | generating scmconfig.h, and we end up with nothing extraneous | |
116 | added to config.h. | |
