emcc should also build these libraries if they don't exist already and it should also take care of building these libraries before using them. In this case you are building a SIDE_MODULE, and under emscirpten anyway, these do not require linking with system libraries such as libc. However, you build system (maybe python's build system) has added I see several possible solutions:
To get something working quickly I think (1) is your best bet. In the long term I think maybe (3) is that right thing to do. |

Thank you. I finally got the answer. Because However, due to my exported function, my code needs to be compiled with I also tried to remove Perhaps I should build Anyway, thank you for your answer! |

i.e. you just want one copy of libc in your final program.. so the main module provides all the libc symbols that the side modules need.. at least that how things normally work with emscripten. We don't support libc as a shared library, but a static library that is designed to be linked only into the main module. |

libc-debug.ais the debug version oflibc.a.. the compiler adds this and other standard libraries to the link line for you.emcc should also build these libraries if they don't exist already and it should also take care of building these libraries before using them.
