undefined reference to `main' during building

[raphael10-collab]

I'm trying to build coreHTTP in Ubuntu 23.10 but I'm getting this error:

raphy@raohy:~/libpeer/dependencies/coreHTTP$ gcc -I source/include/ -I source/interface/ -I source/dependency/3rdparty/llhttp/build/ -DHTTP_DO_NOT_USE_CUSTOM_CONFIG source/dependency/3rdparty/llhttp/build/libllhttp.a  source/dependency/3rdparty/llhttp/src/native/api.c source/dependency/3rdparty/llhttp/src/native/http.c -o coreHTT

collect2: error: ld returned 1 exit status

What am I doing wrong? How to make it work?

You are trying to compile a library. The library is supposed to be used in an application and that is why it does not supply main.

You can look at these samples for learning how to use this library in an application - https://github.com/FreeRTOS/FreeRTOS/tree/main/FreeRTOS-Plus/Demo/coreHTTP_Windows_Simulator.
