Hey, I just compiled cling on Mac OS X 10.9, but it’s unusable, for some reason #include statements fail.

Following the advice on: [url=https://root-forum.cern.ch/t/problems-compiling-on-os-x-10-9/16774/1 compiling on os x 10.9[/url]
Even though I had already installed the Command Line Tools with:
I then tried reinstalling them the same way, but it didn’t work.
I then did the same thing from Xcode, which in the current version just forwards you to the Apple Developer Download website, and tried downloading the .dmg version, and voilà, no header warnings.
I now have undefined symbol errors, similar (or maybe the same?) to this issue on Jira.
Here’s a sample session:

Edit:
I found [url=https://root-forum.cern.ch/t/rootcling-generates-code-for—gnu-cxx-on-osx-with-libc/16683/1 post[/url], apparently it is the same issue.
Edit 2:
cling -stdlib=libstdc++ behaves exactly has just cling, and cling -stdlib=libc++ has the old not found behavior, so I’m compiling again with “-std=c++11 -stdlib=libc++”, let’s see if that does something. I’m just trying out anything that comes to mind, I don’t really have a plan here.
Edit 3:
Nope, every combination I can think about gives the same results: not found headers if I use libstdc++, undefined symbols if I use libc++… I’m out of ideas
When I compile with libc++ and open cling with libc++, it won’t find C++ header files and most statements segfault, read session I put on my first post, that’s what happens.
In your previous result, you do not have a path for libc++ headers.
I rename my libc++ header path to /usr/include/c++/v11, and get the same not found error, I fix it by cling -I /usr/include/c++/v11 -stdlib=libc++
That’s what you need to do.
Thanks, but I tried adding all versions of the headers I have in my computer, both with the .I command and the -I option, and [url=https://root-forum.cern.ch/t/i-cant-include/16840/1 same thing as this log[/url] happens.
