GribApi.XP is a friendly fork of the ECMWF's GRIB API. It makes a few changes to improve cross-platform (hence the XP) parity of features and packages. At the moment, that mostly means improving support for Windows, but changes for all platforms are welcome.

To install the GRIB tools from Chocolatey, run

C:\> choco install grib-tools

• PNG compression support
• OMP multi-threading enabled by default
• grib_exit and grib_assert hooks for custom handling of fatal errors (details coming soon)

You can build directly with Visual Studio using ./build/Grib.Api.Master.sln.

To build x86 and x64 libs together, you can run build\build_gribapi.cmd [re|build] [vs tools version] [Debug|Release] [opt: package version], e.g.

C:\> build\build_gribapi.cmd rebuild 14 Debug

Not scripted yet, sorry :(

1. Delete everything in root/grib_api.
2. Download the latest version from https://software.ecmwf.int/wiki/display/GRIB/Download
3. As administrator (ensures symbolic links are created), extract the files files to root/grib_api directory.
4. Commit the vanilla changes to the local repo.
5. Now you need to update the vcproj files. This is the tricky bit. There are 2 ways to do this. The second is hacky, but much easier.

Open a VS Developer Command Prompt.

> powershell
PS > cd root/grib_api/windows
PS > dir -Recurse *.vcproj | ForEach-Object { devenv /upgrade /q $_.FullName}

Copy the preproccors, output directories, etc from the previous GribApi.XP project files to the new ones.

Do not open the VS Developer Command Prompt. Instead, open the vcproj in grib_api/windows in a text editor. Copy/paste the list of files from the vcproj files into GribApi.XP's vcprojx files.
