WRFDA Compilation Fails - Can't Find Module Files Despite Correct Manual Compilation

[viviq18]

Hi WRF Community,

I'm encountering an issue while compiling WRFDA (v4.2) after successfully building WRF. The error suggests missing .mod files, though I can confirm these files exist in the original WRF directory and can be generated manually. Here are the details:
WRFDA Error:

Fatal Error: Can't open module file 'module_utility.mod' for reading at (1): No such file or directory

When I manually compile module_utility.F90 in WRFDA：

/lib/cpp -P -nostdinc -traditional-cpp -I$WRF_DIR/inc module_utility.F90 > module_utility.f90
mpif90 -c -O2 -fdefault-real-8 -I$WRF_DIR/main -I$WRF_DIR/external/esmf_time_f90 module_utility.f90

This generates module_utility.o and module_utility.mod successfully, but ./compile all_wrfvar still fails.
Then，manually copied .mod/.o files from $WRF_DIR/external/esmf_time_f90/ to $WRFDA_DIR/var/build/ → No effect
