Thin and Puma fail with similar issues - ERROR: Failed to build gem native extension on Mac with [email protected]

Question

Describe the bug I have tried to do a gem install puma and gem install thin and get an error.

I have a brand new Mac that I am setting up: MacOS Catalina 10.15.6 (19G73)

I have worked out that any version <= 4.2.1 works fine on my computer I am using asdf version manager

• Works: gem install puma -v '4.2.1'
• Fails: gem install puma -v '4.3.0' or gem install pumad

Error for Puma

I have tried each of these commands to get this to work

gem install puma

gem install puma -v '4.3.0'  --  --with-ldflags=-L/usr/local/opt/[email protected]/lib  --with-cppflags=-I/usr/local/opt/[email protected]/include

gem install puma -v '4.3.0'  --  --with-ldflags=-L/usr/local/opt/[email protected]/lib  --with-cppflags=-I/usr/local/opt/[email protected]/include --with-opt-dir=/usr/local/opt/[email protected]

I saw on this thread that you need OpenSSL 1.1

I reinstalled openssl

brew reinstall [email protected]

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/[email protected]/certs

and run
  /usr/local/opt/[email protected]/bin/c_rehash

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.

If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc

For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"

For pkg-config to find [email protected] you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"

I tested with these lines in .zshrc

export PATH="/usr/local/opt/[email protected]/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"

Answer 1

The Puma team pointed me to a temporary solution for compiling puma.

gem install puma:4.3.5 -- --with-cflags="-Wno-error=implicit-function-declaration"

I used this variant for the latest version

gem install puma -- --with-cflags="-Wno-error=implicit-function-declaration"

I was also able to use this same technique to with thin, but I have not tested whether the gem works.

gem install thin -- --with-cflags="-Wno-error=implicit-function-declaration"

Lili

This worked for my issue also, and I was also able to specify the version flag so my bundle install succeeded. Just leaving this in case that minor detail has anyone hung up during their app setup process: gem install zipruby -v '0.3.6' -- --with-cflags="-Wno-error=implicit-function-declaration" – Marjie

Answer 2

bundle config build.thin --with-cflags="-Wno-error=implicit-function-declaration"

opened https://github.com/macournoyer/thin/issues/370 to get it fixed or documented in thin
