Hi, I am having truly weird experiences as follows
1) My library, when statically linked, works fine with libverbs 2) My library, when dynamically linked, provides unpredictable errors with libverbs 3) My test programs, in main(), dynamically linked with libverbs, work OK This has been reproduced in several Centos 7.6 InfiniBand networks. I have done extensive debugging; as more and more functions move into main(), my program runs further. Typically, I either segmentation violate inside libverbs ibv_ calls, or I get errno=9 in my library, depending on how much code has moved into the statically compiled main or library. All my code runs fine with a dynamically built main, a statically built library (my product), and -libverbs dynamically linking. Is there any known set of conditions that produces such a situation with recent libverbs? Any specific things to look out for with readelf that would indicate that libfabrics is not going to link properly with a dynamic library? I've read extensively on inter-dll dependencies and proper linking. What's the best practice according to the developers of this library ? :-) Thank you, Tony Skjellum -- Anthony Skjellum, PhD [email protected] Cell: +1-205-807-4968
