Found some articles that seem to provide a solution… unfortunately, I lack the skills to apply it :-)

@hwschuur hello, simply wrap this and the other occurrences in #ifndef __APPLE__ and #endif respectively before and after the offending line, like so (example taken from tensor-convo.cc):

#ifndef __APPLE__
  feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
#endif

Be careful, the line that contains feenableexcept might be different in each file, so add the #ifndef __APPLE__ and #endif combo by hand, don't copy/paste the whole block with 3 lines!

Files that need to be adapted:

first-convo.cc:  feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
mnistposter.cc:  feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
tensor-convo.cc:  feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
tensor-relu.cc:  feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
try-convo.cc:  feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );

Note that tensor-convo-par.cc also contains the line, but it is commented out and thefore can be left as is:

// feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );
