Installation : libsrtp and libsrtp2 not found

[Mehdi Verfaillie]

Hello and thank you for the time you will devote to this post.

I find myself annoyed by this error after running the last command on this follwing gist:

configure: error: libsrtp and libsrtp2 not found. See README.md for installation instructions

I have read the instructions at this address: https://janus.conf.meetecho.com/docs/README.html 

Here are the steps I performed after creating an EC2 instance on Ubuntu 18.04 : https://gist.github.com/Mehdi-Verfaillie/778e331ae59bccd1a90ddfe62a92757a

When I run this commands : 

whereis libsrtp2 libsrtp

I got the following path :

libsrtp2: /usr/lib64/libsrtp2.so
libsrtp: /usr/lib/x86_64-linux-gnu/libsrtp.so /usr/lib/x86_64-linux-gnu/libsrtp.a /usr/lib64/libsrtp2.so

Did I make a silly mistake?

Thank you for your help and for your work on Janus.

First of all don't install libsrtp-dev and compile libsrtp2.2 from source. Choose one of those steps.

If you distro has <1.5 version then you need to build it from source.

Hope it helps

Also, you reference libdir in your config line (which is NOT) part of the readme.  I build srtp locally and things are fine.

I use checkinstall instead of make install, and checkinstall spits out .deb which you can install or upload to your repo, thou result should be the same.

But i guess newer distros habe proper libsrtp version, I'll see to drop that part and just install official ones

Thank you for your answers.

@Mirko Brankovic 

So, I have re-deploy a new EC2 instance on ubuntu 18.04 by choosing not to install libsrtp-dev (and only libsrtp2.2) but I always arrive at the same result.

Maybe I am wrong, but I do not have the impression that libsrtp is pre-installed on my instance. At least I didn't find it..

A question, when you say: "build it from source" is it about not going through aptitude for installation?

@Brian Koblenz

If you talk about the flag

--libdir=/usr/lib64

, I use it because in the readme asks to use it if I use an x86_64 distribution.

Did I do it the wrong way?

Also, how do you build srtp locally ? (noob question)

Thanks a lot guys! 

[Mirko Brankovic]

Yeah, since you git checkout and make from sources.

Strange, i have tried on 16.04 and debian10 and didn't have this problem

No i also followed docs from github readme

[Brian Koblenz]

Look at ur log. 

After you cd libsrtp2.2.0

You ./configure with a reference to a system library location. That is not what it says in the README, so go back to that step and try again

Ok! You was right. It works now that I have removed

--libdir=/usr/lib64

when I ./configure.

I believe I was confused with this: 

I thought I should use it after the ./configure as when installing usrsctp

hi friends,

# whereis libsrtp2 libsrtp

libsrtp2: /usr/lib/libsrtp2.so /usr/local/lib/libsrtp2.so

libsrtp: /usr/lib/libsrtp2.so /usr/lib64/libsrtp.so /usr/local/lib/libsrtp2.so

Libsrtpe is installed and gives the path like this. But I run ./configure --prefix=/opt/janus

checking for LIBSRTP... no

checking for LIBSRTP... no

configure: error: libsrtp and libsrtp2 not found. See README.md for installation instructions

I am getting the error. I saw the same error on this issue, but I couldn't solve it. Will you help?

Thanks.
