As of R 3.6.0 we get the following error on `osx_image: xcode7.3` (El Capitan):

```auto
clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -I/usr/local/include -fPIC -Wall -g -O2 -c reassign.c -o reassign.o
clang: warning: no such sysroot directory: '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk'
In file included from reassign.c:2:
/Library/Frameworks/R.framework/Resources/include/R.h:55:11: fatal error: 'stdlib.h' file not found
# include <stdlib.h> /* Not used by R itself, but widely assumed in packages */
          ^
1 error generated.

```

On my local El-Capitan however `/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk` seems to be available and all works. How do we install this? I tried `before_install: xcode-select --install` but that didn’t help.

That image is old and will not be updated. I suggest dropping it.

I know, it is not our primary platform, but we would still like to test on El Capitan because this is the version of MacOS that CRAN is targeting. Perhaps there is something we can run in `before_install` to get the missing directory `/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk`.

OK I found a workaround, simply remove the `-sysroot` from the compiler flags:

```auto
    - os: osx
      osx_image: xcode7.3
      latex: false
      before_script: sed -i.bak 's/-isysroot /-I/g' $(R RHOME)/etc/Makeconf

```

Only use this workaround for El-Capitain, because `-isysroot` is actually needed on Mojave.

Even if this works, now I’m getting,

```
Installing OS X binary package for MacTeX
$ sudo installer -pkg "/tmp/BasicTeX.pkg" -target /
installer: Error - This package requires Sierra (mac OS 10.12) or higher.

```

Looks like checkmate?

What are the proper incantations to get a working build environment similar to CRAN?

You can add `latex: false` to your El Capitain build to disable latex.

Otherwise just upgrade your `osx_image`.

Yay! It works again, [https://travis-ci.org/OpenMx/OpenMx/jobs/526810159](https://travis-ci.org/OpenMx/OpenMx/jobs/526810159)
