构建由 C 和 C++ 文件组成的库

Question

I have a .so library where all code was written in plain ANSI C, so compiling it is straightforward. Now, I need to add C++ code in it. What would be the compilation process now?

Do I have to compile C++ files with g++ and the rest with gcc , but what about linking into .so file, do I do this with g++ ?

Thanks!

Answer 1

Yes,

• Compile .c with gcc
• Compile .cpp with g++
• Link with g++

Note:
If a C++ function needs to be invokable from C code, wrap it in extern "C" { ... } .
