Compilation errors in OSX 10.9

ROOT
1

Hi,

I’ve been having trouble compiling with ROOT since upgrading to OSX 10.9. I’m running ROOT 5.34.14 (using git checkout -b v5.34.14 v5.34.14; also tried with 5.34.12), and the latest Mavericks command line tools (dated 22 Oct 2013), downloaded from developer.apple.com/downloads/index.action (the xcode-select --install command doesn’t seem to work right now). ROOT itself builds without complaining.

Here is the compilation error I’m encountering. I’ve also attached my config.log file. Any ideas? Random googling implicates libc++, but I’m not sure what to do about it.

Without your code or at least fragment mentioned by the compiler (what is this TAccept.cxx???) it’s a useless guess work.

Show at least, what is this m_cutMap (the declaration) and (probably) the declaration of a member function where you have this compilation error.

Ah, apologies, I’m not so familiar with clang, and got confused by the error/note messages. The problem was internal (const incorrectness that was previously ignored). Thanks, and sorry for the noise.
