[3dprinter-general] Bug#1098270: trimesh: Build fails on s390x due to math errors in autopkgtest

[Gregor Riepl]

Hi Pranav,

> I have started looking at this bug and was able to reproduce it. Continuing my debug, will update further.
Thanks for testing!
I didn't see your message and continued to trace the problem via Qemu.

As far as I can see, it's two exporter modules that incorrectly format float32 values in native endianness instead of converting them to little endian format first.
On import, the values are interpreted correctly, which makes the unit tests fail.

I've pushed a patch to Salsa[1], could you test it and verify that it fixes the issue on real hardware?

Thank you very much,
Gregor
