 ====== Frequently Asked Questions ======
-==== Linking with ''g++ -g'' seems to take ages. ====
+Please see the wiki on [[https://github.com/metno/fimex/wiki/FAQ|github]].
-Use ''-gstabs'' or ''-ggdb'' instead of ''-g''. For debugging, this is better suited to c++ code and works with the GNU utils and most other debugger, too. (But unfortunately  not with /valgrind/.
-==== Problems with a short variable ====
-I have problems with a felt-file with a variable of type 'short'. fimex abborts with<code>change in scaling-factor for parameter: 31,2,1000 consider using float or double datatpye</code> What should I do?
-  - While the netcdf-format allows for only 1 scaling-factor per variable, the felt-format can have a scaling-factor per 2d-slice per variable (that are level*time scaling-factors). You should change the //type// of the variable and its //_FillValue// attribute from //short// to //float// in the file felt2nc_variables.xml.
-  - If you want to save disk-space, and you know that all data of the variable can be subscribed sufficently with a packed short data-array, use the cdmWriterConfig.xml as follows: <code>
-<variable name="31,2,1000" newname="air_temperature" type="short">
-  <attribute name="_FillValue" value="-32767" type="short" />
-  <attribute name="scale_factor" value="0.01" type="float" />
-  <attribute name="add_offset" value="273" type="double" />
-</variable>
-</code> In this example, the temperature will be described with an accuracy of 0.01ºC and a range of -327.66ºC (I know thats below 0K) to 327.66ºC
