@gsohler It seems we may be hitting the same error :)

Nice work @gsohler :)

You must specify `CXX=gcc-11`. I got the exact same error when debugging this and that's how you fix it :slightly_smiling_face:

FWIW I'm working on getting things working with GCC12. This involves changes or patches to some dependencies.

Should we maybe reduce the scope of what formats curv should support due to small resources available to maintain it?

@meleano It seems "aligned_alloc" is part of glibc. Your MSYS2 environment is probably not update enough. I would suggest refreshing it and again using gcc-11.

Thank @theohonohan - I've tried such SDFs but they don't work well for the reason of needing to make a closed shape.

It seems a few smart people have come along and figured out some potential SDFs for this! https://www.shadertoy.com/view/3dtBR4

@theohonohan you can't just arbitrarily combine SDFs. There are "proper SDFs" that are necessary for further manipulations. An example is the offset manipulation. If you don't have a proper SDF,...

@doug-moen this issue is apparent because of marching cubes right? Maybe if we forced an external offset on the models (while devving) it'd make this problem more apparent. I'm thinking...
