WRF Version 3.6.1 was released on August 14, 2014.
WRF Version 3.6.1
(Posted 10/15/2014)
Problem: Trouble Building WRFV3 for Various Compilers, and testing on IBM Platforms
Solution: Download this tar file
You will need to place the files in the following directories:
Makefile - in the top WRFV3/ directory
fortran_2003_fflush_test.F - in the WRFV3/tools/ directory
fortran_2003_flush_test.F - in the WRFV3/tools/ directory
configure -in the top WRFV3/ directory
module_wrf_error.F - in the WRFV3/frame/ directory
Once you have these files in the right places, do a 'clean -a', then reconfigure and recompile WRFV3.
Compilation Troubles (Posted 10/15/2014)
Problem: There is an additional space between 'mpi_x_comm_size' and the opening parentheses in one of the if-def lines in the 'module_io_quilt.F' file. This causes the compile to break for some compilations, since the substitution pattern is not found.
Solution:Replace with this newer version of module_io_quilt.F. Place in the WRFV3/frame/ directory and change the name to 'module_io_quilt.F', then recompile code (no need to do a 'clean -a' or to reconfigure).
Building WRF Serially (Posted 10/15/2014)
Problem: WRF is not capable of building serially with no nest.
Solution: Replace with this version of mediation_feedback_domain.F. This has some additional code that will now allow it to build serially with no nest. Place in the WRFV3/share/ directory and rename to 'mediation_feedback_domain.F', then recompile the code (there is no need to do a 'clean -a' or to reconfigure).
IBM Compilers (Posted 10/15/2014)
Problem: Some IBM compilers (particularly older ones) complain that the code is too complex to build (referring specifically to 'module_first_rk_step_part1.o).
Solution: Replace with this version of module_first_rk_step_part1.F, which removes unnecessary code. Place in the WRFV3/dyn_em/ directory and rename to 'module_first_rk_step_part1.F', then recompile the code (there is no need to do a 'clean -a' or to reconfigure).
Restart Issues (Posted 8/14/2014)
Problem: Tests revealed that the following options do not produce correct restart results: TEMF, Thompson aerosol-aware (mp_physics=28), and global runs
Solution: Work will be underway to fix these; a fix will be provided when available
MAC Mavericks OS (Posted 8/14/2014)
Problem: Current WRF/WPS code does not support CLANG, the default c compiler on this Mac OS
Solution: Work is underway to resolve this issue. In the meantime, one can install gcc instead
