10 | # generate a .def file | |
11 | # | |
12 | # It does this by parsing the header files and looking for the | |
47339f61 | 13 | # prototyped functions: it then prunes the output. |
d02b48c6 | 14 | # |
6928b617 | 15 | # Intermediary files are created, call libcrypto.num and libssl.num, |
1a53f1d6 | 16 | # The format of these files is: |
948d0125 | 17 | # |
e863d920 | 18 | # routine-name nnnn vers info |
948d0125 | 19 | # |
e863d920 MC |
20 | # The "nnnn" and "vers" fields are the numeric id and version for the symbol |
21 | # respectively. The "info" part is actually a colon-separated string of fields | |
22 | # with the following meaning: | |
948d0125 RL |
23 | # |
24 | # existence:platform:kind:algorithms | |
25 | # | |
26 | # - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is | |
609b0852 | 27 | # found somewhere in the source, |
948d0125 RL |
28 | # - "platforms" is empty if it exists on all platforms, otherwise it contains |
29 | # comma-separated list of the platform, just as they are if the symbol exists | |
30 | # for those platforms, or prepended with a "!" if not. This helps resolve | |
62dc5aad | 31 | # symbol name variants for platforms where the names are too long for the |
948d0125 | 32 | # compiler or linker, or if the systems is case insensitive and there is a |
62dc5aad RL |
33 | # clash, or the symbol is implemented differently (see |
34 | # EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found | |
35 | # in the file crypto/symhacks.h. | |
36 | # The semantics for the platforms is that every item is checked against the | |
5012158a LJ |
37 | # environment. For the negative items ("!FOO"), if any of them is false |
38 | # (i.e. "FOO" is true) in the environment, the corresponding symbol can't be | |
a303e9a6 | 39 | # used. For the positive items, if all of them are false in the environment, |
62dc5aad RL |
40 | # the corresponding symbol can't be used. Any combination of positive and |
41 | # negative items are possible, and of course leave room for some redundancy. | |
948d0125 RL |
42 | # - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious. |
43 | # - "algorithms" is a comma-separated list of algorithm names. This helps | |
44 | # exclude symbols that are part of an algorithm that some user wants to | |
45 | # exclude. | |

56 | # When building a "variant" shared library, with a custom SONAME, also customize |
