then, i wrote a simple hello world code, and tried to compile it :

[root@server ~]# vim hello.cr

[root@server ~]# crystal build hello.cr

E-vent5858B-ase.o: In function `*Event::Base#new_event<Int32, LibEvent2::EventFlags, Fiber, &Proc(Int32, LibEvent2::EventFlags, Pointer(Void), Nil)>:Event::Event':

it failed, something about "LibEvent2::...", so then i tried to install libevent2-devel, but it conflict with libevent-devel :

# yum install libevent2-devel

Loaded plugins: fastestmirror

.....

Error: libevent2-devel conflicts with libevent-devel-1.4.13-4.el6.x86_64

You could try using --skip-broken to work around the problem

You could try running: rpm -Va --nofiles --nodigest

2. by using tar.gz

the steps were simple: download and extract the released binary, then try to compile :

[root@server ~]# tar xvfz crystal-0.26.1-1-linux-x86_64.tar.gz

...

[root@server ~]# ./crystal-0.26.1-1/bin/crystal build hello.cr

/usr/bin/ld: cannot find -levent (this usually means you need to install the development package for libevent)

collect2: ld returned 1 exit status

Error: execution of command failed with code: 1: `cc "${@}" -o '/root/hello' -rdynamic -lpcre -lgc -lpthread /root/crystal-0.26.1-1/share/crystal/src/ext/libcrystal.a -levent -lrt -ldl -L/usr/lib -L/usr/local/lib`

it failed, so then, libevent2 is required to be installed :

[root@server ~]# yum install libevent2-devel

Loaded plugins: fastestmirror

I didn't notice a git tag for these releases, would that be possible or is it available elsewise?

Thanks.

Somewhat unrelated, but I find that my server (using SSL) seems to sometimes "stop accepting new connections" recently, possibly after the upgrade to 0.26.1. This ring a bell at all to anyone?
