Quick installation guide
Here is an example of a list of commands you could use to install ecCodes. It is assumed “>” is the shell prompt.
| Code Block |
|---|
> tar -xzf eccodes-x.y.z-Source.tar.gz > mkdir build ; cd build > cmake –DCMAKE_INSTALL_PREFIX=/path/to/where/you/install/eccodes ../eccodes-x.y.z-Source ... > make > make check > make install |
Note that for the testing step ("make testcheck") you need to be connected to the internet (and set the relevant "http_proxy" environment variable if you must use a proxy) so data files can be downloaded for the tests. You can however download all the data files in one go (See the data tarball link at the top of the Releases page)
