i'm having a problem when i perform metgrid.exe in WPS. No errors occured performing geogrid.exe and ubgrib.exe. Here is the error:

[zkq@ustc WPS-4.3.1]$ ./metgrid.exe

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

It shoud be noted that a warning ourred during ./congiure WRF-4.3.3:

NETCDF4 IO features are requested, but this installation of NetCDF
/home/abdul/Build_WRF/LIBRARIES/netcdf
DOES NOT support these IO features.

Please make sure NETCDF version is 4.1.3 or later and was built with
--enable-netcdf4

OR set NETCDF_classic variable
bash/ksh : export NETCDF_classic=1
echo csh : setenv NETCDF_classic 1

Then re-run this configure script

!!! configure.wrf has been REMOVED !!!

I set NETCDF_classic variable using csh : setenv NETCDF_classic 1
An error ocuured during ./compile WPS as well: The metgrid.exe is genertaed
I solved this problem following the instrudtion in this post.
The WRF is version 4.3.3 and the WPS is version 4.3.1. i don't konw if this can cause so many errors.
 
Is this a nested case? can you upload your full namelist.wps for me to take a look? Thanks.

My situation is exactly the same as his, including the previous unsuccessful generation of meogrid, and the solution is also based on his method, but I also ran into the same problem.By the way,No errors occured when performing geogrid.exe and ubgrib.exe.
