Hello @marciocamello

Could you run the following command and show me the result?

benjamin:~$ openssl version 
OpenSSL 1.1.0g  2 Nov 2017

benjamin:~$ strings /usr/local/lib/libsrtp2.a | grep HMAC_CTX
HMAC_CTX_free
HMAC_CTX_new

Hi @sfreet

OpenSSL 1.1.0g 2 Nov 2017

HMAC_CTX_cleanup
HMAC_CTX_init

Did you install libressl instead of libssl-dev?

[marciocamello]

no, i am install libssl-dev

libssl-dev is already the newest version (1.1.0g-2ubuntu4.3).
Os seguintes pacotes foram instalados automaticamente e já não são necessários:
g++-5 javascript-common libass5 libboost-filesystem1.58.0 libboost-system1.58.0 libcapnp-0.5.3 libegl1-mesa libfdk-aac0 libgles2-mesa libjs-excanvas libllvm6.0 libprotobuf-lite9v5 libprotobuf9v5 libpython3.5
libtxc-dxtn-s2tc0 libva-drm1 libva-egl1 libva-glx1 libva-tpi1 libva-wayland1 libva-x11-1 libva1 libvpx3 libwayland-egl1-mesa x11proto-dri2-dev x11proto-gl-dev

The message shows that the srtp library refers to a previous version of the ssl library or libressl.

I get the following message now in the following.
(install libressl -> install libsrtp -> uninstall libressl -> install libssl-dev -> compile OvenmediaEngine)

/usr/local/lib/libsrtp2.a(hmac_ossl.o): In function `srtp_hmac_dealloc':
hmac_ossl.c:(.text+0xd9): undefined reference to `HMAC_CTX_cleanup'
/usr/local/lib/libsrtp2.a(hmac_ossl.o): In function `srtp_hmac_alloc':
hmac_ossl.c:(.text+0x235): undefined reference to `HMAC_CTX_init'
collect2: error: ld returned 1 exit status
core/build_executable.mk:7: recipe for target 'bin/DEBUG/OvenMediaEngine' failed

In this situation, I solved it as follow. (recompile and reinstall libsrtp)

$ sudo apt-get install libssl-dev => Try it again to make sure. 
$ (curl -OL https://github.com/cisco/libsrtp/archive/v2.2.0.tar.gz && tar xvfz v2.2.0.tar.gz && cd libsrtp-2.2.0 && ./configure --enable-openssl && make && sudo make install)

If libsrtp installation is finished and the output is as follows, it will work.

$ strings /usr/local/lib/libsrtp2.a | grep HMAC_CTX
HMAC_CTX_free
HMAC_CTX_new

(Try to run again "make clean" and "make" OvenMediaengine source)

If the issue is not resolved, please let me know again.
