This issue stems from the nature of case-insensitive systems, such as Mac. Some of the source code files (with file extension “.F”) need to be pre-processed by modifying the original files. This is done by making a copy with the file extension “.f”. For case-insensitive platforms, these new files overwrite the old ones, and do not get created properly, causing the failure.
A handful of modifications can be made in the UPPV4.1 source code to address this issue. These changes have not been extensively tested.
1. Change the file extension from .F to .FTN for 7 files.
sorc/ncep_post.fd/GFSPOST.F → sorc/ncep_post.fd/GFSPOST.FTN
sorc/ncep_post.fd/GFSPOSTSIG.F → sorc/ncep_post.fd/GFSPOSTSIG.FTN
sorc/ncep_post.fd/GRIBIT.F → sorc/ncep_post.fd/GRIBIT.FTN
sorc/ncep_post.fd/INITPOST.F → sorc/ncep_post.fd/INITPOST.FTN
sorc/ncep_post.fd/MICROINIT.F → sorc/ncep_post.fd/MICROINIT.FTN
sorc/ncep_post.fd/kinds_mod.F → sorc/ncep_post.fd/kinds_mod.FTN
sorc/ncep_post.fd/params.F → sorc/ncep_post.fd/params.FTN
2. Modifications to two makefiles for the new file extension naming (Line numbers use the UPPV4.1 release).
sorc/ncep_post.fd/makefile_dtc
