I tried building your latest libev-1.3e with eventxx on Red Hat with:
$ gcc --version
gcc (GCC) 3.4.5 20051201 (Red Hat 3.4.5-2)
with the following flags to workaround a priority event issue:
-Dev_flags=1 -DEVLIST_ACTIVE=1. This both solves a compile error and
actually causes a priority function call to throw an exception.
First I got the following errors:
./eventxx: In destructor `eventxx::dispatcher::~dispatcher()':
./eventxx:794: error: cannot convert `eventxx::internal::event_base*'
to `event_base*' for argument `1' to `void
eventxx::internal::event_base_free(event_base*)'
Very strange, but by declaring struct event_base at the beginning of
event.h, right before the struct event, solved my problem. I suspect
this to be an old gcc bug-I did not see this on OSX gcc
(4.0-something).
I hope you will consider something like the following patch, which
solved my problem. I was able to get a bufferevent read I/O to work
with libev.
$ diff -u ~/libev-1.3e/event.h .
