compile C and C++ code into one binary in Linux

Sometimes you have a project written in C and you want to add some code (may be open source software) which is provided in C++. So you may want to call a function written in C++ from C. For that purpose, you have to change the function prototype of the concerned C++ function like:

The ifdefs are only needed, if you are including the header file containing this code into a C and C++ source file!

When it comes to compiling, use the specific compiler like gcc for C code and g++ for C++ code. Compile each sourcefile(s) into a object file like:

The last line will link the object files together.
