Here are some more details about this specific migrator:

The transition to CUDA 12 SDK includes new packages for all CUDA libraries and build tools. Notably, the cudatoolkit package no longer exists, and packages should depend directly on the specific CUDA libraries (libcublas, libcusolver, etc) as needed. For an in-depth overview of the changes and to report problems see this issue. Please feel free to raise any issues encountered there. Thank you! :pray:

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I was debugging the CI failure, and I noticed something interesting. cuQuantum DSOs have a few symbols from libm.so.6@GLIBC_2.27, however on CUDA 11 we were able to patch them out fine (which turns out to be an illusion, read on) but not on CUDA 12.

With the current CUDA 12 migrator, I find out the reason is that the aarch64/ppc64le images in use have different glibc versions:

• quay.io/condaforge/linux-anvil-aarch64-cuda:11.2 (for CUDA 11): glibc 2.28
• quay.io/condaforge/linux-anvil-aarch64 (for CUDA 12): glibc 2.17

These can be checked via either ldd --version or objdump -T /lib64/libm.so.6 (the DSO loaded at the test stage). I believe this contributes to some subtle issues that we (at least I) previously were puzzled about. This is also causing the illusion: we never patched it fully (because patchelf didn’t update .gnu.version_r table), it’s just that in the CF CI the problem is hidden due to the image in use.

Now that it's clear using glibc 2.27 for aarch64/ppc64le is inevitable, some tests have to be skipped due to lack of the infrastructure support (tracked here), which is still WIP. Since tests can't be run anyway, let me merge #36 to here and turn on cross-compilation. At least we get some speedup in CI.
