Using clang compiler
|
|
==========================
|
|
|
|
clang++ compiler is **highly recommended** for anyone developing in C++ since :
|
|
|
|
* It has very nice and useful error messages, much nicer than intel or gcc.
|
|
* It implements most of the new C++11 standard.
|
|
|
|
clang/llvm is now the standard compiler on OS X, but it is open source
|
|
and works very well on linux too.
|
|
|
|
Version
|
|
---------
|
|
|
|
* TRIQS compiles on clang, version 3.0 and later.
|
|
|
|
* Recommended version is 3.1 (latest stable).
|

|
Get and install clang
|
|
------------------------
|
|
|
|
If you have precompiled version in the `LLVM dowload page <http://llvm.org/releases/download.html>`_,
|
|
use it. E.g. on Ubuntu 12.04 LTS ::
|
|
|
|
wget http://llvm.org/releases/3.1/clang+llvm-3.1-x86_64-linux-ubuntu_12.04.tar.gz
|
|
tar xzf clang+llvm-3.1-x86_64-linux-ubuntu_12.04
|
|
sudo mv clang+llvm-3.1-x86_64-linux-ubuntu_12.04 /opt/clang
|
|
# add /opt/clang/bin to your path
|
|
# use clang++...
|
|
|
|
Otherwise, it is in fact quite easy to compile clang from source, just follow the
|
|
`instructions <http://clang.llvm.org/get_started.html#build>`_.
|
|
|
|
Usage
|
|
--------------
|
|
|
|
In the current version, when compiling with clang, say (provided clang++ is your path of course) ::
|
|
|
|
CXX=clang++ cmake path_to_TRIQS_source_directory .... others options ...
