Installation error: suffix or operands invalid for `movq'

[dimidd]

I tried installing using gem install nmatrix on osx, using gcc 5.2.0.

In file included from nmatrix.cpp:283:0:

I've never tried to install with GCC 5.2, and this is a new one. What happens if you use 4.9?

same error, the warnings are slightly different:

Googling around for this error, it only seems to occur when a project has some inline assembly code, which nmatrix doesn't have, so that's a little puzzling.

It seems like this error sometimes comes from some sort of 32- vs 64-bit incompatibility, but these days I think OS X is always purely 64-bit, so that also doesn't really make sense.

@dimidd, does the .s file in /var/folders still exist after you finish building? You could try to look at it, or upload (a snippet of) it for us to look. Hopefully it will provide some clue as to where this is coming from.

[dimidd]

@wlevine, unfortunately no. Perhaps I should put a breakpoint in ruby_nmatrix.c and inspect the assembly.

[wlevine]

There should be an option to get gcc to output the assembly. gcc -S, not
quite
sure if it would be trivial to get that working in the nmatrix build. This
also looks like it might be useful, to get an annotated version of the
assembly:http://stackoverflow.com/a/19083877/4992690

The makefile has a lots of flags variables, where should I add -S?

[wlevine]

Sorry for the slow response. You can add it to CFLAGS and CPPFLAGS. Then when you run make you should end up with some ".o" files that are actually not object files, but assembly files in disguise. You can run as on them to isolate where the error is.

@dimidd Have you had any luck? I can try this week if you're still struggling.

Sorry for the late response, I had a problem installing ATLAS. I've finally managed to install using macports, and added -L/opt/local/lib in LDFLAGS. Now when running bundle exec rake spec I have a different issue:

This kind of stuff seems to happen when linking between things compiled by different compilers. I'm not sure why I didn't mention that before. I may have only just recognized the error.
