For future reference, I opened and closed issue 17016 <https://github.com/numpy/numpy/issues/17016#issue-673841413> on github.
The culprit was a `Broken Toolchain` due to a mismatch between Arch's newer ld and conda's older ld. Solution was to move the default ~/conda/envs/doc-build-38/compiler_compat/ld to ~/conda/envs/doc-build-38/compiler_compat/bak_ld Then, the build went smoothly. -- Sent from: http://numpy-discussion.10968.n7.nabble.com/ _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@python.org https://mail.python.org/mailman/listinfo/numpy-discussion
