fatal error C1083: Cannot open include file: 'grib_api.h': No such file or directory also tried clone pygrib repo https://jswhit.github.io/pygrib/installing.html but grib_api.h not exists in the path. can anyone help with this issue. I am trying to make an executable using windows. the code running perfect on macos and linux. thank you

grib_api.h is part of the eccodes C-library that pygrib depends on. You can set the ECCODES_DIR env var to the installation path to fix this.

hi @jswhit , here i downloaded EcCodes-win-x64.zip (https://github.com/moonpyk/eccodes-build-windows/releases) file.

unzip and save in C:
set all the paths mentioned here https://github.com/moonpyk/eccodes-build-windows/blob/master/README.md the issue is still same : fatal error C1083: Cannot open include file: 'grib_api.h': No such file or directory here are my path: ECCODES_DEFINATION_PATH : C:\ECMWF ECCODES_DEFINITION_PATH : C:\ECMWF\share\eccodes\definitions ECCODES_DIR : C:\ECMWF\bin Is there anything im missing? I installed vs code build tools and eccodes using pip. thank you
