I am currently working with Quantum ESPRESSO version 7.0 and Libxc version 6.0.0. The functional I am using is specified as Input_dft='XC-000I-000I-000L-130L-707L-000I'. For the Meta-GGA exchange, I have selected the TASK exchange functional with id=707. However, I encountered the following error:
Error in routine matching_shortIDs (1):
libxc needed for this functional, but it is not linked
<br></span></p><p style="border: 0px solid rgb(227, 227, 227); box-sizing: border-box;"><span style="font-size: 16px; white-space-collapse: preserve;">I am unsure of the cause of this error. Could you provide guidance on what might be causing this issue?
Additionally, since the TASK functional only provides an exchange functional, I am uncertain about which correlation functional to select. Could you explain the logic behind choosing an appropriate correlation functional in this context?
Thank you for your assistance.
Best regards,
zhouchao</span></p>
