[R-SIG-Mac] Testing R 3.4.0 RC r72542

[Berend Hasselman]

Most of the problems I mentioned yesterday with R 3.4.0 RC still exist.
(see thread https://stat.ethz.ch/pipermail/r-sig-mac/2017-April/012287.html).

There is now a libc++ in the R framework: /Library/Frameworks/R.framework/Versions/3.4/Resources/lib/libc++.1.dylib

1.

Rcpp was not updated and thus still links to /usr/local/clang4/lib/libc++.1.dylib and not to
/Library/Frameworks/R.framework/Versions/3.4/Resources/lib/libc++.1.dylib

2.

The private  package using C++ still links to Apple's libc++.1.dylib and not the one from clang4.
Nor to the libc++.1.dylib in the R framework.
It is however being built with clang4 using the method suggested by Simon.

Output from otool -L ..:

regts.so:
	regts.so (compatibility version 0.0.0, current version 0.0.0)
	/Library/Frameworks/R.framework/Versions/3.3/Resources/lib/libR.dylib (compatibility version 3.3.0, current version 3.3.3)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1259.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.1.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

3.

The problem with help pages in R.app I mentioned in my second mail still exist.
(using [R.app GUI 1.70 (7334) x86_64-apple-darwin15.6.0]).

For example after ?ls this message appears.

starting httpd help server ... done
2017-04-19 10:14:31.505 R[3447:52508] App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

And the window displaying the help is blank.
Any request for help using ? of help() shows a blank window.
