#4722: Remove Shared build workaround #4725
Conversation
|
In Jenkins, looks like the OpenMPTarget-Clang build failed due to the compiler crashing. It's seemingly in the front-end, so nothing to do with this as far as I can tell. Same failure appears on https://cloud.cees.ornl.gov/jenkins-ci/blue/organizations/jenkins/Kokkos/detail/Kokkos/7811/pipeline for PR #4724 |

I just tested that this doesn't break shared library builds on Intel 18 either - tests link and pass |

This code was introduced in #2288. We need to make sure removing these lines do not break support for shared libraries.

#4722 (comment) I tested on gcc and Intel with shared libraries

If it works now, I'm very happy without this workaround. It would be interesting what "fixed" it, though.

Likely some subsequent change in how Kokkos defines its targets in CMake, so that the need for PIC actually gets picked up like it's supposed to. It would take combing through the combined history of Kokkos's build files and releases of CMake itself to pinpoint it, though.

The workaround just implements the CMake default for shared libs, so from my side it is ok to drop that.

It seems that there is some testing on the Trilinos side if I read #4722 correctly.
I tested Kokkos with the reproducer @ndellingwood posted with the fix I proposed here, with both Intel and GCC. |

Failure (Clang crash in OpenMPTarget build) is clearly unrelated and under investigation elsewhere. |
Fixes #4722
