[Wien] OMP Error in combination with ELPA during compilation with ifx version higher than 2025.1

[Michael Fechtelkord]

Dear colleagues,


I want to point out to an unresolved issue concerning versions of ifx 
2025.2 and higher. It seems Intel has changed the OMP library and that 
concerns ELPA (currently version 2025.06.002). While compilation and 
check of ELPA works with either version of ifx .. the compilation of 
WIEN2k (seclr4_tmp_.F) leads to the errors shown below. Compiling ELPA 
with ifx and OMP 2025.1 and further compilation of WIEN2k with ifx 
2025.3 does not give any error.

Has somebody an idea how to get rid of the error? It would be nice to 
compile all with the same intel ifx version and not always ELPA 
separately with version 2025.1


Best regards,

Michael

happen if ELPA is compiled with ifx 2025.1)
