Description Susi Lehtola 2026-01-18 11:17:36 UTC

The log file for the latest OpenBabel build in rawhide shows

-- Eigen3 version .. found in /usr/include/eigen3, but at least version 2.91.0 is required
-- Could NOT find Eigen3 (missing: EIGEN3_VERSION_OK) (Required is at least version "2.91.0")
-- Could NOT find Eigen2 (missing: EIGEN2_INCLUDE_DIR EIGEN2_VERSION_OK) (Required is at least version "2.0.0")


Due to the lack of Eigen, the conformer search code is not built, causing link and install issues in other packages.

Please fix the issue ASAP.
