This is simple tool to generate a C interface from C++ source code using clang libtooling. CPP2C currently is a proof of concept, and only applies to https://github.com/samanbarghi/uThreads, to generate the C interface. The code is explained in details in this blog post.
git clone https://github.com/samanbarghi/CPP2C
cd CPP2C
mkdir build
cmake ..
make
sudo make install
git clone https://github.com/samanbarghi/uThreads
cd uThreads
cpp2c include/uThreads.h -- -x c++ -I./src -I/usr/include/x86_64-linux-gnu/c++/5/ -I/usr/include/c++/5.4.0 -std=c++11
You can find the output in outpu folder: cwrapper.h is the header that should be included in C files, and cwrapper.cpp is in C++ and is responsible to convert C++ pointers to C and vice versa.
