Add the following files: + +- android/event2/event-config.h +- bsd/event2/event-config.h +- linux/event2/event-config.h +- mac/event2/event-config.h +- solaris/event2/event-config.h +- evconfig-private.h + +These files are taken from libevent-2.1.12-stable built on the development +environment indicated by the first path component. You have to run +"./configure" and "make" to get all of the pre-processing done. The +event-config.h header can then be found in include/event2/ sub-directory and +evconfig-private.h can be found in the root source directory. + +You then need to modify the EVENT__SIZEOF_* constants in the generated Linux, +Android, and BSD headers to be appropriate for both 32-bit and 64-bit platforms. +Mac doesn't need this since only 64-bit is supported. Use __LP64__ to +distinguish the two cases. If you get something wrong, the CHECK_EVENT_SIZEOF +static assertions in message_pump_libevent.cc will fail. If a new constant is +added, also add a static assertion for it to message_pump_libevent.cc. + +You also need to modify the EVENT__HAVE_ARC4RANDOM and EVENT__HAVE_ARC4RANDOM_BUF +constants in the generated Linux header to account for the results of the arc4random +and arc4random_buf configure checks. + +2. No additional patches are needed at this time, but be careful to avoid +clobbering changes to the various event-config.h files which have been customized +over time to avoid various build bustages. |
