Immediately after rebasing from Fedora Silverblue 41 to Fedora Silverblue 42, all my CUDA Fortran kernels failed to launch when running from the host Fedora Silverblue 42 system:
It seems to be related to the upgrade in Fedora from gcc 14 to gcc 15 (which also required a re-installation of the HPC_SDK in order to enable nvfortran to again work).
In order to be able to run my existing CUDA Fortran kernels, I had to launch from a Fedora 41 or lower distrobox (which has gcc 14.2.1). Hopefully the HPC_SDK will be updated in due course to run with gcc 15’s stricter security policies. (the screenshot mentions pygame but the same error occurs with all my CUDA Fortran kernels).
