I will try to figure out how to cross-compile gsl in 32bit mode on my machine, it might take a few days for me to resolve this. In the mean-time, I don't think there is any problem in using GSL in 32 bit, just that the test tolerances are too tight for 32 bit to pass the tests.

Looking at updating the Fedora gsl package to 2.1, but we're seeing test failures on 32-bit builds:


Just to muddy the waters a bit more, on Windows I'm getting the same failures with gsl-2.0 and gsl-2.1, but only with 32-bit gcc-4.8.2. With 64-bit gcc-4.8.2, 32-bit gcc-4.9.2 and 64-bit gcc-4.9.2 there's no such issue.

This suggests to me that there might be a gcc bug at play here.

(Sorry Patrick - I don't usually use gcc-4.8.2 and didn't discover this problem until a few hours ago.)
