Curious about how Blaze(next generation of NumPy) will be like, I tried to install with

pip install Blaze

The tarball blaze-0.1.tar.gz is downloaded, but error raised:

Clang++ is required to build Blaze.

Questions:

What is Clang++? I assume it is not a Python package/module. It seems to be something related to C++.

What to install to meet this requirement? I am using Ubuntu 14.04.

Thanks in advance!

    Clang is a a compiler. It is required probably because blaze wants to compile some of it's files. – RedX Jun 25 '14 at 10:40

Blaze no longer depends on Clang.

@aterrel's answer to use conda is still ideal if you want to install non-Python dependencies like HDF5 or BColz.

conda install blaze  # installs many useful packages on Mac, Linux, Windows

But if you don't need these (or are able to install them via other channels) then Blaze itself can be installed by pip.

pip install blaze --upgrade

Clang++ is a C++ compiler like gcc. Try sudo apt-get install clang to install it.

To install Blaze, you should try to use Anaconda or Miniconda (then conda install blaze), unfortunately the PyPI package is not well-maintained. To use pip try from the development version:

pip install git+https://github.com/ContinuumIO/blaze.git

The requirement of Clang++ has been removed (in v0.4 I believe).

Additionally the development version is quite a bit different from that version.
