Fix Missing Headers Compiling on macOS Mojave
Update
It would appear that the latest version of Xcode has removed the macOS_SDK_headers_for_macOS_10.14.pkg file. I am currently searching for alternative solutions.
While trying to compile PHP extensions after installing macOS Mojave, I was butting up against a ton of missing header file errors including php.h and zlib.
After several hours of beating my head against my desk and Googling/Stack Overflowing I found the solution.
Ends up you just need to force re-install the header files. Special thanks to @sfdye for the solution!
$ sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /If you get an error about that file not existing, you probably simply don't have the Xcode command line tools installed which can be remedied simply as follows:
$ xcode-select --installComment by: Matthew Koski on Oct. 6, 2018
Thank you so much for this! Google please make this the number one result when someone is having trouble with headers suddenly on Mojave. For me it was ctypes.h.

```cd /Library/Developer/CommandLineTools/Packages
open macOS_SDK_headers_for_macOS_xx.pgk
```
Try this if you still missing C headers.

I get :installer: Error - the package path specified was invalid: '/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg'.
whats wrong?

I found a solution that works for me. With 10.14.5, the '/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg' package is removed.
Instead you have to point it to where the headers are in the Xcode package. In my .bash_profile I added this:
export CPATH="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include"

bundle config --local build.mysql2 "--with-ldflags=-L/usr/local/opt/openssl/lib"

Thanks for posting this! A gotcha I ran into is xcode-select was already installed but without header files. To correct this remove the old command line tools with:
$ (sudo) rm -rf /Library/Developer/CommandLineTools
Then install command line tooks ala:
$ xcode-select --install
Then finally your header file line.

@Brian EngI love you, Thank you. This worked for me.

This file does not exist! Why is this working for so many people but not me???

@z Knight I had the same issue with mine - I went to https://developer.apple.com/download/more/ and downloaded the Command Line Tools (macOS 10.14) for Xcode 10.3 June 22, 2019.This added the .pkg to the file. however it didn't fix the issue I was having (being told I need to install development tools first).

When usingsudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target / -allowUntrusted
i get the error:
installer: The install failed (The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.)
Mac OS 10.14.6
If I don't add "-allowUntrusted", it states "Certificate used to sign package is not trusted.".
Does anybody else have the same problem?
Comment by: Micha on Nov. 1, 2019
removing and reinstalling the CLT solved the issue...

I found this page Googling a similar problem for Nokogiri so I thought I would share another hard-won lesson on macOS gembuilding.On macOS Catalina, while trying to bundle install a Gemfile with a Nokogiri dependency, I kept hitting:
> libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.
Solution:
brew install libiconv
bundle config build.nokogiri --with-iconv-dir=/usr/local/opt/libiconv
bundle install --path vendor/bundle
Cheers!

Im using MacOS 10.14.5For me, the solution was:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
cd /Library/Developer/CommandLineTools/Packages/
open macOS_SDK_headers_for_macOS_10.14.pkg
Cheers!

4-liner above worked for me, posted by MacrossEO on Nov. 28, 2019my own context was for local ruby build for heroku app,
in which ruby.h was not found because mac os xcode upgrade
dropped its default install of (some? all?) include files;
in order to get a successful
bundle install
and specifically
sudo gem install nokogiri -v '1.10.4' --source 'https://rubygems.org/'

May be because I use DuckDuckGo -- this came up in the first few links! Thanks, helped me sort out why 'gem <> install --user-install'
Comment by: annoporci on May. 18, 2020
Tried MacrossEO's suggestion, but to begin with I have no `Packages` subdirectory under `CommandLineTools`, instead I have:/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk
Is there anything I could try next? Thanks.
Comment by: João on May. 24, 2020
I have the same issue. No Packages folder,, just:/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk
/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk
macOS 10.15 (Catalina)
I keep getting this error when compiling: fatal error: 'string.h' file not found...
Thanks

I'm fighting with same problem.`export CPATH="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include"`
not helped, and after reinstall xcode old version (MacOSX10.14.sdk) is gone
Comment by: Yujuan Gui on Sep. 24, 2020

Comment by: Valera on Oct. 22, 2020
With Catalina 10.15 I've added the line below to my ~/.bash_profile:export CPATH="/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include"
Check twice, that this path exists. There are might be some variants, e.g. MacOSX10.14.sdk or MacOSX10.15.sdk
