I try to run Nginx, but i have error: eventfd() failed (38: Function not implemented)

I found this patch (https://forum.nginx.org/read.php?29,258676,258685#REPLY) to 1.9.0, i cannot do diff so i do it manualy.

So i found ngx_epoll_init(ngx_cycle_t

And now my file:

static ngx_int_t ngx_epoll_init(ngx_cycle_t *cycle, ngx_msec_t timer);
#if (NGX_HAVE_EVENTFD)
if (ngx_epoll_notify_init(cycle->log) != NGX_OK) {
- return NGX_ERROR;
+ ngx_epoll_module_ctx.actions.notify = NULL;
}
#endif

But i have compiler error

src/event/modules/ngx_epoll_module.c:105: error: expected identifier or '(' before 'if'
make[1]: *** [objs/src/event/modules/ngx_epoll_module.o] Error 1

Any ideas how to make it working?
