I already mentioned this in the NG but we still have this weird notification when running dub:

dub: /usr/lib64/libcurl.so.4: no version information available (required by dub)

distro: "CentOS release 6.5 (Final)"
Linux version 2.6.32-358.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 00:31:26 UTC 2013
dmd: 2.065 b3
dub: 0.9.21 RC 4

any ideas ?

A CentOS/RPM based build is in the works (see #245 and the installer scripts in https://github.com/rejectedsoftware/dub/tree/master/installer/rpm). But there is still some setup left to be done for the CI system to build this automatically.

Awesome! Thank you very much! Is it gonna be there on time for the release ?

Yep, that's more or less what is still holding up the release.

Hi

i've tested the RC5 under CentOS 6.5 (64-Bit minimal) on new installed VM. After installing the dependencies (dmd 2.064, libevent, libevent-devel, libevent2 via rpm, gcc and so on) I've tried to build the app_skeleton of vibe.d.
First try has thrown the following output:

[root@localhost app_skeleton]# dub

app-skeleton: ["app-skeleton", "vibe-d", "libevent", "openssl"]

After checking the installation of libevent, libevent2, libevent-devel twice I've made a symlink to fix this issue:

[root@localhost app_skeleton]# ln -s /usr/lib64/libevent_pthreads-2.0.so.5.1.9 /usr/lib64/libevent_pthreads.so

Next try gave me:

Do you have any idea what went wrong?

So there is no way around building libevent from source when one wants to run vibe.d on centos ?

Not sure, actually. There seem to be matching "libevent2-devel" packages
when searching the web [1], but we didn't test them an I have no idea
how trustworthy that repository actually is.

So its not neccessary to built from sources. You can install the rpm (http://rpm.pbone.net/index.php3/stat/4/idpl/21761893/dir/centos6/com/libevent-2.0.13-14.2.x8664.rpm.html) instead.

Good to know. Is pbone.net a trusted source for RPM packages? All those
banners didn't make a very reputable impression to me at first glance.

I usually use Debian based OS so I really don't know if pbone.net is a trusted rpm source. But it is also mentioned in the official Fedora documentation as a useful source for RPMs [1]. I think/hope that they wouldn't recommend this site if its not trustworthy ;-) But if you want to be on the safe side you should built it from the source.
