| Note |
|---|
For the IBM xlc compiler we recommend disabling the creation of 'shared libraries' which is known to cause problems with this version of grib_api. |
In this example, note the use of the '_r' form of the IBM compiler to ensure grib_api is compiled 'thread-safe'. This is important as grib_api will be called by multiple threads with OpenIFS. |
