Postgresql gem install pg 0.18.4 passes, bundle install fails

Question

Mac OS El Capitan

Bundle install fails with:

An error occurred while installing pg (0.18.4), and Bundler cannot continue.

Make sure that `gem install pg -v '0.18.4'` succeeds before bundling.

Running 'gem install pg -v '0.18.4' results in:

Building native extensions.  This could take a while...
Successfully installed pg-0.18.4
Parsing documentation for pg-0.18.4
Done installing documentation for pg after 4 seconds
1 gem installed

Yet running 'bundle install' again fails. Any suggestions? I've tried uninstalling and reinstalling postgresql with homebrew with no luck

I have got a similar error now on macOS Catalina, but I was not able to successfully run

gem install pg -v '0.18.4'

I found this issue in the puma gem (I know this is another gem) that helped me solve the issue: https://github.com/puma/puma/issues/2304.

There, I found this:

Clang now enables -Werror=implicit-function-declaration by default:

Clang now reports an error when you use a function without an explicit declaration when building C or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on). This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets for this diagnostic. (49917738)

And this:

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

So, I was able to build pg with:

gem install pg -v '0.18.1' -- --with-cflags="-Wno-error=implicit-function-declaration"

Spent many hours debugging this and your flag fixed it for me – ohiock Aug 27 '20 at 21:26

This also resolved the issue with pg 0.18.4 in MacOS Big Sur 11.0 Beta – Mike Szyndel Sep 14 '20 at 13:43

The following worked for me: `gem install pg -v '0.18.4' -- --with-cflags="-Wno-error=implicit-function-declaration"` – Martin Sommer Jan 05 '21 at 18:23

Thank You! Another Big Sur user rescued - works for pg 1.2.3. and Postgres 13 – MrAleister May 03 '21 at 17:42
Worked like a charm in Catalina, thank you! – Joseworks Jun 08 '21 at 13:33

The same issue has been faced with all the gems that rely on native extensions such as pg, puma, ffi, etc I have solved them by passing -- --with-cflags="-Wno-error=implicit-function-declaration"

ex:

gem install pg -v '0.18.4' -- --with-cflags="-Wno-error=implicit-function-declaration"
gem install ffi -v '1.12.2' -- --with-cflags="-Wno-error=implicit-function-declaration"
gem install puma -v '4.3.1' -- --with-cflags="-Wno-error=implicit-function-declaration"

this worked for me - changing the `config` value suggested by @haley-mnatzaganian did not work for some reason – subelsky Feb 11 '21 at 15:59
confirmed working on Big Sur with ffi 1.9.23 – Tom Harrison May 28 '21 at 17:40

I had to combine Benito's answer and jasonm's answer like below before running bundle (credit to Unixmonkey):

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

Thanks! I had to make a minor change to get this to work: `bundle config build.pg '--with-cflags="-Wno-error=implicit-function-declaration"'`. The build options needed to be passed in without the additional `-- ` prefix. See https://bundler.io/man/bundle-config.1.html#BUILD-OPTIONS for more info. – amenon Apr 29 '21 at 18:41

on macOs Monterey I had to go into `~/.bundle/config` and change it to `BUNDLE_BUILD__PG: "--with-cflags='-Wno-error=implicit-function-declaration'"` -- the `bundle config` command did not properly escape the quotations. – vinhboy Jan 05 '22 at 04:28

For me this worked after removing single quotes: ```bundle config build.pg --with-cflags="-Wno-error=implicit-function-declaration"``` – Narendra Apr 20 '22 at 10:49

This isn't an an answer, as such, but it may point you in the right direction... If indeed gem pg has successfully compiled, as you have indicated... Then it maybe that your Ruby project isn't referring to the correct gemset, somehow. As it appears it is attempting to install it again when you bundle install, this should not happen if pg has been compiled and installed in your current gemset. Are you using RVM on your system? Can you also provide more output?

Good thought but as far as I can tell they're the same: jmintz-laptop:radar console$ which gem /Users/USER/.rbenv/shims/gem console$ which bundle /Users/USER/.rbenv/shims/bundle – jasonm Apr 06 '16 at 21:32
