Cannot find link libraries. Is there a way to not link with the specific libraries that are missing. It's not a system I can configure myself. Thanks,

I am wondering why netcdf-c brings in those 3 unnecessary libraries and is there a way not have link with those 3 libraries by configuring netcdf?

Thanks

I'm not certain where these dependencies are being inherited from, they are not libraries we check for or link against. I would suspect they are dependencies used by mpi, but I cannot say for certain. Linking on my machine (MacOS) does not result in the same dependencies.

What platform are you working on? If it's a standard linux distribution, I can stand up a VM easily enough and see if I can recreate the issue.

Thanks, This is on a Linux HPC machine:
Linux version 4.18.0-425.19.2.el8_7.x86_64 ([email protected]) (gcc version 8.5.0 20210514 (Red Hat 8.5.0-16) (GCC))

I ran into the same 3 library linking issues with either intel or gnu compilers. In my initial message I meant I could manually link if I remove the 3 libraries so the 3 libraries are not essential. I have no idea how configure picked up the 3 libraries either.

Right now I am using gnu 8.5.0 openmpi 4.0.7, here is how I am setting up configure. I can build netcdf-c with this configure on my local linux machine. Let me know if I can provide any other information.
