Pelegant error: passed size is not equal to expected size for SDDS_DATASET structure

[duanz]

Dear all,

I've just compiled from source the latest elegant version 2023.4.0 & SDDS.5.6, on a cluster with almalinux 9, the GCC version is 11.4.1 20231218, and the MPICH version is mpich-4.2.1

elegant runs fine. But when I run a simple Pelegant example that computes the elegant example/parallel/DA with mpiexec -np 10 Pelegant parTrack2.ele, I got the following error information:

Error:
passed size is not equal to expected size for SDDS_DATASET structure
Passed size is 2680, library size is 2672

from all the 10 cores.

Does anyone has some clues how to solve this problem? Thanks!

Best,

Zhe

The error comes from the SDDS library. It is saying that the library was compiled with a different SDDS.h file than Pelegant was. The first thing I would do is to run "ldd Pelegant" to see if it is linking to a shared library SDDS1.so. It may be using an older version somehow. Check the timestamp on the SDDS1.so file to see it is the one you recently compiled. Personally, I compile our programs without building SDDS1 as a shared library and only a static library. You could do this by adding SHARED_LIBRARIES=NO to your extensions/configure/CONFIG file at the bottom. But if you do, then you will have to make sure that you clear out all the *.so files that you already built. They would be in extensions/lib/linux-x86_64/

You would then recompile everything.
