linux installation error

[Xavier Giroux-Bougard]

Hello all,

I am trying to install pyamg from source on a linux mint machine. but I get the following error message:

linux@linux-MacPro ~/Desktop/pyamg-2.1.0 $ sudo python setup.py install

Running from numpy source directory.

I am not quite certain why the compiler is failing, any suggestions?

Thanks fro your time!

It looks like it's having difficulty finding a c++ compiler. 

1. What version of Mac OS X are you running?
2. Have you installed the Mac command-line tools with Xcode (so that you have a compiler)
3. What is the output of running c++ --version?

As an alternative, you could run pip install pyamg but again you'll need a working compiler.
