| # generate a .def file | |
| # | |
| # It does this by parsing the header files and looking for the | |
| # prototyped functions: it then prunes the output. | |
| # | |
| # Intermediary files are created, call libeay.num and ssleay.num,... | |
| # Previously, they had the following format: | |
| # | |
| # routine-name nnnn | |
| # | |
| # But that isn't enough for a number of reasons, the first on being that | |
| # this format is (needlessly) very Win32-centric, and even then... | |
| # One of the biggest problems is that there's no information about what | |
| # routines should actually be used, which varies with what crypto algorithms | |
| # are disabled. Also, some operating systems (for example VMS with VAX C) | |
| # need to keep track of the global variables as well as the functions. | |
| # | |
| # So, a remake of this script is done so as to include information on the | |
| # kind of symbol it is (function or variable) and what algorithms they're | |
| # part of. This will allow easy translating to .def files or the corresponding | |
| # file in other operating systems (a .opt file for VMS, possibly with a .mar | |
| # file). | |
| # | |
| # The format now becomes: | |
| # | |
| # routine-name nnnn info | |
| # | |
| # and the "info" part is actually a colon-separated string of fields with | |
| # the following meaning: | |
| # | |
| # existence:platform:kind:algorithms | |
| # | |
| # - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is | |
| # found somewhere in the source, | |
| # - "platforms" is empty if it exists on all platforms, otherwise it contains | |
| # comma-separated list of the platform, just as they are if the symbol exists | |
| # for those platforms, or prepended with a "!" if not. This helps resolve | |
| # symbol name variants for platforms where the names are too long for the | |
| # compiler or linker, or if the systems is case insensitive and there is a | |
| # clash, or the symbol is implemented differently (see | |
| # EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found | |
| # in the file crypto/symhacks.h. | |
| # The semantics for the platforms is that every item is checked against the | |
| # environment. For the negative items ("!FOO"), if any of them is false | |
| # (i.e. "FOO" is true) in the environment, the corresponding symbol can't be | |
| # used. For the positive itms, if all of them are false in the environment, | |
| # the corresponding symbol can't be used. Any combination of positive and | |
| # negative items are possible, and of course leave room for some redundancy. | |
| # - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious. | |
| # - "algorithms" is a comma-separated list of algorithm names. This helps | |
| # exclude symbols that are part of an algorithm that some user wants to | |
| # exclude. | |
