openmpi-5.0.0rc6 build failing on -ludev #10291
Description
Building the openmpi-5.0.0rc6 tarball fails during link due to a missing -ludev.
Not sure where the udev comes from and why it changed between rc5 and rc6.
Background information
What version of Open MPI are you using? (e.g., v3.0.5, v4.0.2, git branch name and hash, etc.)
- openmpi-5.0.0rc6
- gcc 9.1.0
- ucx 1.11.1
Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.)
Build from source tarball. Same configure options/setting worked with openmpi-5.0.0rc5.
Please describe the system on which you are running
- Operating system/version: linux
- Computer hardware: ppc64
- Network type: infiniband
