You'll find all c-ares details and news here: http://c-ares.haxx.se/ + + +NOTES FOR C-ARES HACKERS + +The following notes apply to c-ares version 7.6.1 and later. + +* The distributed ares_build.h file is only intended to be used on systems + which can not run the also distributed configure script. + +* The distributed ares_build.h file is generated as a copy of ares_build.h.dist + when the c-ares source code distribution archive file is originally created. + +* If you check out from CVS on a non-configure platform, you must run the + appropriate buildconf* script to set up ares_build.h and other local files + before being able of compiling the library. + +* On systems capable of running the configure script, the configure process + will overwrite the distributed ares_build.h file with one that is suitable + and specific to the library being configured and built, this new file is + generated from the ares_build.h.in template file. + +* If you intend to distribute an already compiled c-ares library you _MUST_ + also distribute along with it the generated ares_build.h which has been + used to compile it. Otherwise the library will be of no use for the users of + the library that you have built. It is _your_ responsability to provide this + file. No one at the c-ares project can know how you have built the library. + +* File ares_build.h includes platform and configuration dependant info, + and must not be modified by anyone. Configure script generates it for you. + +* We cannot assume anything else but very basic compiler features being + present. While libcurl requires an ANSI C compiler to build, some of the + earlier ANSI compilers clearly can't deal with some preprocessor operators. + +* Newlines must remain unix-style for older compilers' sake. + +* Comments must be written in the old-style /* unnested C-fashion */ + |
