[Help-gsl] Error in GSL 2.1 Installation on Mac using GCC 5.1.0 compiler

[Ron I. Eytan]

Hello,

I'm running into an error when trying to build and install GSL 2.1 on my
Mac. I'm running Yosemite (10.10.5) and using the GCC 5.1.0 compiler.

I'm consistently running across the following error during "make". It's
happened on two different machines and occurs at the same point in the
"make" process. The error is:

-------------------------------------------------------------------------------------------------------------------------------

I was looking around the internet and it seems like this or a similar error
occurs when making GSL 2.0 using Xcode 7. It seems to get hung up on
"statistics".

Any recommendations here? Is this a bug, or a problem with my compiler or
system OS? Many thanks in advance for the help.

Cheers,
Ron
