WRF-Chem v3.9.1 has trouble compiling on derecho


New member
My WRF-Chem v3.9.1 used to compile successfully on Cheyenne. However, it is encountering compilation issues since the system was changed to Derecho. I have made changes to the WRF-Chem v3.9.1 code, so I cannot use a newer version of WRF. Here are the modules and directories loaded before compiling:

module load intel-classic/2023.2.1
module load ncarcompilers/1.0.0
module load cray-mpich/8.1.27
module load craype/2.7.23
module load netcdf-mpi/4.9.2
module load ncarenv/23.09
module load cray-mpich/8.1.27
module load netcdf/4.9.2
module load ncl/6.6.2
module load hdf5/1.12.2
export WRF_CHEM=1
export WRF_EM_CORE=1
export WRF_KPP=1
export WRF_NMM_CORE=0
export FLEX_LIB_DIR="/glade/work/yingxiao/flex-2.5.3/"
export YACC="/usr/bin/yacc -d"

Then I select option #15/#24 for configuring, but there are always some issues when compiling. Could you help me with this problem? Thank you so much for your help!
