CGO: C++ Standard Library (darwin)

Getting Help
1

I am experimenting with mac’s deprecated reflective loading functionalities. I have a go program that invokes the go compiler to create binaries, but apple’s implementation of reflective loading is reliant on C++ for exception handling.

As I understand it, CGO is only for C and requires a C wrapper to use C++ code, but I cannot figure out of it is possible to just link standard libraries. I tried passing -lc++ and -lc++abi as linker flags along with -L /usr/lib, and some other things, but no luck.

What would be the simplest way to do this? Please feel free to ask for elaboration if necessary, I am new to programming, go, and still learning the C toolchain, and playing with software that is slightly above my paygrade, so I might have missed some important concepts.

The simplest method should be:
1.go->c++: go as a launcher
Export your c++ code to a c library, and then go uses cgo to call it.
2.c+±>go: c++ as a launcher
Export your go code to a c library through cgo, and then your c++ code calls it.
3. Find the corresponding go code implementation and learn

Okay, I figured out I was linking the libraries the wrong way. Instead of setting go env to CGO_LDFLAGS=‘-lc++ -lc++abi’ I was trying to set them in the command with the -ldflags flag. Now, I can successfully link the libs, but am still getting the error, which indicates an error with my software. Thank you
