How can I pass an array from perl to inline C++?

I can't tell if this is a bug or what. The following code works with `Inline::C` but not `Inline::CPP` ``` #!/usr/bin/perl use warnings; use Inline C; my @array = (1..10); print findAvLen(\@array), "\n"; __END__ __C__ int findAvLen(AV* arrayIn) { return av_len(arrayIn); } ``` The above runs fine, but replace `C` with `CPP`, and I get the error `Can't locate auto/main/findAvLen.al in @INC...` I can get other inline c++ code to work. It is possible, for instance, to pass a list of variables to inline code with an ellipsis as they do in this example, but I wonder why AV* isn't working! For instance, I will want to use a subroutine to converts perl arrays passed to C++ into vectors, e.g. `void perl2vector(AV* ar, std::vector<T> &v) {...}`, rather than inserting code to perform such conversion into every C++ function I write that takes an array argument. How could I use that example's syntax to pass the perl array to such a converter? This does seem to be a bug, but in the meantime, uesp has found a workaround: ``` int findAvLen(SV* arrRef) { AV * arr = MUTABLE_AV(SvRV(arrRef)); return av_len(arr); } ``` `arr` is now equivalent to the `arrayIn` desired in the example code above.
