Thanks for the great help. Compiling with Swig 1.3 did not help (same error).
I figured out, reading at this [1], that the the GeoServer GDAL plugin
must use gdal 1.9.2, as must use imageio-ext-gdal-bindings-1.9.2.jar
(I don't see that .jar available for other versions that 1.9.2).
Therefore I believe the Swig error was caused by using gdal java
bindings mixed between 1.9.2 and 2.1.3 versions.

Therefore, I am trying to compile on Ubuntu 16.04 gdal 1.9.2, but I am
now getting in this error [2].
Is there a workaround for this? The only alternative for me would be
to install Ubuntu 14.04LTS in the server, where I know that gdal 1.9.2
can be compiled correctly.

Thanks
