ecCodes compiles with GCC instead of NVHPC

Applies to

• Machine: Balfrin
• Build: ICON compiled without emvorado

Symptom

• At runtime, you may see the cryptic error:

  libgomp: TODO
  

  or other strange runtime crashes.

Cause

• Due to a known bug in ICON’s build system (spack), eccodes is compiled with GCC instead of NVHPC if emvorado is not enabled.

Workaround / Fix

• In your spack.yml, explicitly require eccodes to be built with NVHPC:

  - eccodes%nvhpc
  

Status

• Known bug. Workaround required. Not yet fixed Spack.
