@ -5,6 +5,15 @@ how to handle exceptions or other errors
Here is some advice and some tricks to use when dealing with thrown exceptions, error conditions and the like in Sol.
Linker Errors
-------------
There are lots of reasons for compiler linker errors. A common one is not knowing that you've compiled the Lua library as C++: when building with C++, it is important to note that every typical (static or dynamic) library expects the C calling convention to be used and that Sol includes the code using ``extern 'C'`` where applicable.
However, when the target Lua library is compiled with C++, one must change the calling convention and name mangling scheme by getting rid of the ``extern 'C'`` block. This can be achieved by adding ``#define SOL_USING_CXX_LUA`` before including sol2, or by adding it to your compilation's command line.
Catch and CRASH!
