BF: NETCDFPAR "Error" in build log when option not used (#1651)

TYPE: bug fix KEYWORDS: netcdfpar, Error SOURCE: internal DESCRIPTION OF CHANGES: IMPORTANT: Without these mods, every commit since the parallel netcdf4 IO mods will fail the DA build test in the regression test. For example, at least these commits: ``` fed10f4 Adding the WRF-Solar EPS model (#1547) 0bda5e0 Fix 4dvar build failure after commit 8b5bfe5 (#1652) 8b5bfe5 Thompson AA enhancements: BC aerosol, biomass burning emissions, and … (#1616) 9dc68ca After testing with UFS/GFS/FV-3, some tuning knob changes to Thompson-MP and icloud3 (cloud fraction) scheme (#1626) 96fd889 Update HONO, TERP, and CO2 emissions (#1644) 64fb190 SFCLAY=1, add shallow water roughness calculation (#1543) 609c2fc New module firebrand_spotting for WRF-Fire (#1540) 75bfe6d MYNN PBL clouds in photolysis option 4 (TUV) (#1622) f8c4b13 Fix runtime error when using sf_surface_mosaic = 1 with use_wudapt_lcz = 0 (#1638) b511c70 Run-time option for climate GHG for radiation (#1625) 8194c66 Bug fix for configuration option INTEL:HSW/BDW (#1645) 16c9287 bug fixes for radar_rf_opt=2 (#1642) a82ce24 Sync with NoahMP Github version with all NoahMP updates since v4.3 (#1641) 7b642cc Bug fix for TAMDAR T VarBC (#1632) 92fd706 fix WRFDA build for Parallel netcdf-4 IO (#1634) ``` Problem: With PR #1552 "Parallel netcdf-4 IO option" (SHA1 3cd4713), when then code was built without the new parallel NetCDF4 compression, the build log had an `Error`. ``` > grep Error compile.log Fatal Error: Cannot open module file ‘wrf_data_ncpar.mod’ for reading at (1): No such file or directory make[2]: [diffwrf] Error 1 (ignored) make[2]: [diffwrf] Error 1 (ignored) wrf_io.f:117: Error: Can't open included file 'mpif.h' make[2]: [wrf_io.o] Error 1 (ignored) Fatal Error: Cannot open module file ‘wrf_data_ncpar.mod’ for reading at (1): No such file or directory make[2]: [field_routines.o] Error 1 (ignored) make[2]: [libwrfio_nfpar.a] Error 127 (ignored) make[2]: [libwrfio_nfpar.a] Error 1 (ignored) ``` The problem was related to constructing the object files in the io_netcdfpar directory. When the option is not selected at compile time, then we do not care about errors in the directory that will never be used. Solution: If the NETCDFPAR option is not selected at compile time, then SKIP going into the io_netcdfpar directory all together. LIST OF MODIFIED FILES: m Makefile m arch/Config.pl m arch/configure.defaults m configure TESTS CONDUCTED: 1. Without the NETCDFPAR parameter set, the build for the io_netcdfpar directory is bypassed: ``` cd ../io_netcdfpar ; \ echo SKIPPING make -i -r NETCDFPARPATH="/glade/u/apps/ch/opt/netcdf/4.7.3/gnu/9.1.0" \ cd ../io_netcdfpar ; \ echo SKIPPING make -i -r NETCDFPARPATH="/glade/u/apps/ch/opt/netcdf/4.7.3/gnu/9.1.0" \ ``` 2. When the NETCDFPAR env variable is set, the build includes the io_netcdfpar directory: cd ../io_netcdfpar ; \ make -i -r NETCDFPARPATH="/glade/u/apps/ch/opt/netcdf/4.8.0/gnu/9.1.0" \ cd ../io_netcdfpar ; \ make -i -r NETCDFPARPATH="/glade/u/apps/ch/opt/netcdf/4.8.0/gnu/9.1.0" \ ``` 3. Jenkins tests are all PASS.
