Background information
What version of Open MPI are you using? (e.g., v4.1.6, v5.0.1, git branch name and hash, etc.)
v5.0.4, v5.0.5
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 dist tarball for 5.0.4 and 5.0.5 using conda-forge compilers.
Please describe the system on which you are running
- Operating system/version: macOS 14.5
- Computer hardware: m1 (ARM)
- Network type: N/A
Details of the problem
Our builds of openmpi rely on $LDFLAGS to successfully link -lgfortran, at least in the cross compiling configuration. However, #12650 has a typo where LDFLAGS is saved in $LDFLAGS_save_xcode but restored from $LDFLAGS_xcode_save, which is never set, and thus empty. This has the effect that after this bit of configuration is run, $LDFLAGS is lost.
Fixing the variable names to match each other fixes the failing builds, as seen here with this patch.
