Are you sure this is a bug in Passenger? Yes

Question 1: What is the problem?

• What is the expected behavior? The nginx Passenger module should compile successfully

• What is the actual behavior? Compilation fails with the following error

• How can we reproduce it? Ubuntu 18.04.3 LTS (comes with OpenSSL 1.1.1) Compile OpenSSL 1.1.1c into /usr/local

sudo mkdir -p /usr/local/openssl/src
curl -sS https://www.openssl.org/source/openssl-1.1.1c.tar.gz | sudo tar -xz --strip 1 -C /usr/local/openssl/src
cd /usr/local/openssl/src
sudo ./config --prefix=/usr/local/openssl --openssldir=/usr/local/ssl --libdir=lib enable-ec_nistp_64_gcc_128 no-nextprotoneg no-weak-ssl-ciphers no-ssl3 -Wl,-rpath=/usr/local/openssl/lib
sudo make -j 16 && sudo make install

Compile the Passenger nginx module

sudo mkdir -p /usr/local/phusion
curl -sSL https://github.com/phusion/passenger/archive/release-6.0.2.tar.gz | sudo tar -xz --strip 1 -C /usr/local/phusion
cd /usr/local/phusion
bundle install
rvmsudo rake nginx CACHING=false EXTRA_PRE_CXXFLAGS="-I/usr/local/openssl/include" EXTRA_PRE_CXX_LDFLAGS="-L/usr/local/openssl/lib -Wl,-rpath=/usr/local/openssl/lib"

Question 2: Passenger version and integration mode: open source 6.0.2

Question 3: OS or Linux distro, platform (including version): Ubuntu 18.04.3 LTS

Question 4: Passenger installation method:

[ ] RubyGems + Gemfile [ ] RubyGems, no Gemfile [ ] Phusion APT repo [ ] Phusion YUM repo [ ] OS X Homebrew [X] source tarball [ ] Other, please specify:

Question 5: Your app's programming language (including any version managers) and framework (including versions): Ruby 2.3.8, installed through RVM 1.29.9

Question 6: Are you using a PaaS and/or containerization? If so which one? Amazon EC2

Question 7: Anything else about your setup that we should know? Identical configuration was used on Amazon Linux 2 and it worked fine

This doesn't seem to happen for me on a fresh 18.04.3, though I stuck with the system openssl 1.1.1.
