Building on Ubuntu 16, missing SSL during ./configure I am trying to build bitcoind on Ubuntu 16 64-bit. I have installed the dependencies and have built it fine many times on other machines.

During ./configure, I am getting

checking whether the Boost::Unit_Test_Framework library is available... yes
checking for dynamic linked boost test... yes
checking for mismatched boost c++11 scoped enums... ok
checking for SSL... no
configure: error: openssl  not found.


I have run sudo apt-get install libssl-dev and tried it, also tried brew install openssl, still no dice.

Before, I was getting a missing pkg-config at this point, even though I had installed it. I installed pkgconf and also installed it via brew, and now it's complaining about openssl, which is definitely installed.

$ which openssl
/usr/bin/openssl


Any ideas? Frankly, I'm stumped.

UPDATE:

I built openssl from source, now I'm getting this:

checking for mismatched boost c++11 scoped enums... ok
checking for SSL... yes
checking for CRYPTO... yes
checking for EVENT... no
configure: error: libevent not found.


I'm not sure what is going on... it seems it cannot find packages installed via apt-get for some reason.
I fixed the issue by installing extra libraries, the whole list

sudo apt-get install -y autoconf g++ make openssl libssl-dev libcurl4-openssl-dev

sudo apt-get install -y libcurl4-openssl-dev pkg-config

sudo apt-get install -y libsasl2-dev
