The last time I tested the installation routine, shrec/UltrafastSecp256k1/main was 4.1.0.7 and our codebase wouldn't accept compilation without bitcoin-core/secp256k1/0.7.0. There may be drift in parameterization or change in behavior since then. As your log ends during Ultrafast compilation, I'd guess cuda libraries are missing during linking. it would be a behavior change since last I looked where there was fail-over into silent disabling of cuda. I'd prefer it to be a configuration error if a necessary dependency for configuration isn't found.

Currently working through autotools changes to support ultrafast. Will likely loop back soon after, so hopefully in the next week I have a better story for you.

Any updates? This is the actual error that happens:

Ultrafast builds fine on my other machine w/o nvcc btw
pmienk17:58
I don't have the hardware to test any build options other than CPU. So no, I've got nothing new.

Disabling OpenCL in the build options seems to work, but not sure if that's a valid configuration (i.e. cuda on, opencl off)
pmienk22:46
well, Cuda on doesn't mean it actually built. gotta check the log
pmienk22:46
OpenCL needing to be disabled means it tried to build with OpenCL, and couldn't instead of detecting that it wasn't supported by your environment and autodisabling.
pmienk22:46
it's not ideal from my perspective to do that fallback
pmienk22:47
but if you have Cuda support, then you've got something that should work on your hardware
pmienk22:49
see the cmake configuration output from ultrafast
neillm22:50
Yeah, it finds both cuda and opencl on my machine (because they're both there and working), but it fails on that missing header error above
pmienk22:51
cool! run it yet?
neillm22:51
Haven't tried yet

gonna need @evoskuil for that one
evoskuil22:59
Yep, that's a break in the table verticalization work.
