Bug Description

Binary package hint: clang

The packages summary for the clang package currently reads:

  "Clang project is a new C, C++, Objective C and Objective C++ front-end
  for the LLVM compiler. Some of its goals include the following:
  .....
   *A single unified parser for C, Objective C, C++, and Objective C++
   * Conformance with C/C++/ObjC and their variants"

But, the c++ front-end is not included, but most would assume from the summary that it would be.

One of the following should happen to fix this issue:

 1) The package summary should specify that the c++ front-end is not included
 2) The front-end should be included in this package
 3) A new package "clang++" should be build

I believe that C++ frontend is definitely included. "clang -x c++" is your friend.

That didn't work, it still gives the same error I've seen when I built
clang from the svn sources and didn't build the c++ frontend or forgot to
tell it where the c++ libraries are. It gives multiple "undefined
reference" to c++ libraries when compiling, even with your suggested -x
c++. Last time I built clang from the svn sources it built a clang++
binary, I can't remember if I had to enable building of the c++ frontend.
Either way, the clang package doesn't seem to compile c++ files. Either the
c++ frontend (clang++) isn't being build or the c++ library setup is not
being configured correctly.

Actually, it seems that a symlink from clang to clang++ would be all that's needed. (And to c++-analyzer fromccc-analyzer.)

I can confirm that the symlink to clang++ works. It compiled my c++
files without library errors.
Can this be added to the official clang package?

Here’s a trivial packaging fix that makes scan-view (bug 574719) and clang++ work. I’ve tested it in my PPA <https://launchpad.net/~anders-kaseorg/+archive/ppa>; I can now compile a C++ program with clang++.
