== Notes ==<br />
<br />
C++ code that use C shared libraries needs to specify this fact to the compiler. This can be defined with the ''extern "C"'' keyword, in this way:<br />
<br />
<source lang="c"><br />
extern "C" <br />
{<br />
#include <grass/gis.h><br />
}<br />
</source><br />
<br />
The C++ compiler will understand that the functions defined in gis.h are coded in C. If it is not specified the linking step will throw an error stating that the symbols for the C functions were not found in the shared library.<br />
