SSL certificate verification problem on Mac OS 10.10 Yosemite

[wilkens]

Getting a little ahead of things since Yosemite is still in beta, but ... calls to ngram() fail when running on Yosemite with the following error:

> library(ngramr)
> ngram("programmer")
Error in function (type, msg, asError = TRUE)  : 
  SSL: certificate verification failed (result: 5)

Not a showstopper since I still have 10.9 systems, of course, but thought you might want to know. Thanks for all your work on the package!

Here's information about my setup. Short version: R 3.1.1, RStudio 0.98.1028, Mac OS 10.10, ngramr 1.4.3. Full output of version:

Should have said explicitly: Everything works as expected using the same versions under OS 10.9.

Thanks for letting me know. I'm still on 10.9 myself, so hadn't come across this. Looking here: http://stackoverflow.com/questions/23287685/devtoolsinstall-github-error-in-function-type-msg-aserror-true-not-se suggests it could a libcurl issue. Certainly ngram uses Rcurl.

Thanks, Sean. Don't know if system libcurl info is helpful, but FWIW, Mac OS 10.9.4 appears to use libcurl.4 from curl-78.94.1. My Yosemite machine is at home; will post that version tonight when I have access.

OK, thanks Matthew.

Here's the same info from Yosemite (public beta 2, FYI), pulled via strings /usr/lib/libcurl.dynlib:

PROGRAM:libcurl.4 PROJECT:curl-83.1.1

And for comparison's sake, the output of curl --version on Mavericks:

curl 7.30.0 (x86_64-apple-darwin13.0) libcurl/7.30.0 SecureTransport zlib/1.2.5
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp 
Features: AsynchDNS GSS-Negotiate IPv6 Largefile NTLM NTLM_WB SSL libz 

And on Yosemite:

curl 7.37.1 (x86_64-apple-darwin14.0) libcurl/7.37.1 SecureTransport zlib/1.2.5
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp 
Features: AsynchDNS GSS-Negotiate IPv6 Largefile NTLM NTLM_WB SSL libz 

Alright, will leave you alone on this now. No biggie for me, since I have a workaround, but let me know if you want me to try anything to help chase it down.

Just checking - is this still a problem?
