This project demonstrates how to call C++ code from Go program without the need of using SWIG.

The basic idea is to write a C wrapper of C++ code, and use cgo to call this C wrapper.

git clone -b develop https://github.com/wangkuiyi/go-cpp
cd go-cpp/c++
scons
cd ../go
export GOPATH=`pwd`
cd src/go_prog
go install
DYLD_LIBRARY_PATH=$GOPATH/../c++/ $GOPATH/bin/go_prog

Note that you need to install SCons to build the C++ part. In order to install SCons on Mac OS X, you can use Homebrew.

If you are using Linux, the last command to run the demo program is:

LD_LIBRARY_PATH=$GOPATH/../c++/ $GOPATH/bin/go_prog
