Run ls ./var/build/*.exe | wc -l to check if 43 executables were successfully compiled.
Run ls ./var/obsproc/src/*.exe to check if obsproc.exe exists.

Note

ADIOS2 have not yet been integrated well into WRFDA 4dvar.

Execute ldd ./var/build/da_wrfvar.exe and check that there is not any libadios2_xxx.so.x linked.
