Re: [Bug-gsl] gsl-1.15 fails 'make check' on Mac OS

[Steve Brosnan]

Hi,

A similar problem was reported by Joost Bakker on 12 Nov 2011 (Subject: 
[Bug-gsl] gsl 1.15 on mac osx 10.7.2) except the errors involved convergence of 
singular value decomposition. The full output file was > 6 MB, but here are a 
few snippets from a 'make check' I just did under Mac OSX 10.7.3 (many, many 
cases for different choices for matrix A gave similar failures):

==================
1 of 1 test failed

The issue may involve the newer machines. An older MacBook Pro with Mac OSX 
10.6.8 did not have the problem. But a new iMac (quad-core i5) with 10.7.2 and 
also 10.7.3 fails the tests shown above.

I tried to understand the issue by pulling the test SVD section of code from 
the GSL and compiling it, along with whatever was needed to get it to compile 
and link, in Xcode, but was unable to reproduce the errors.  It ran fine. I 
know that's not very helpful, but I offer it for what it's worth.

Regards,

Steve Brosnan
