go: call cpp lib example

Example Project. Call C++ Code from go via a C wrapper lib.

libtest.cc and libtest.h

C-Code and C++-Code with a C-wrapper, which is both called by Go.

dynamic.go

compiles to a dynamically linked binary.

static.go

compiles to a statistically linked binary. It is a bit tricky to link external dependency’s statistically. but it is possible.

Mixtures of static and dynamic linking are also possible. Like linking the C-wrapper statistically and the external dependency’s dynamically.

Makefile

compiles and runs both versions. This Makefile is needed to compile the CPP part of the Project and build the C-lib.
