Here is some advice and some tricks to use when dealing with thrown exceptions, error conditions and the like in Sol. 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! Catch and CRASH!
