When trying to compile my project, I am getting undefined reference to 'reflex::Input::file_get(char*, unsigned long long)' error.

I exactly know where that function is. It is in a file called input.cpp I have tried my best to link it. But I'm unable. Here is the steps I did:

Compiled input.cpp to input.o. (g++ -isystem..\RE-flex\include -c ..\RE-flex\lib\*.cpp).
Created libreflex.a from input.o. (ar -rcs .\bin\libreflex.a *.o).
Built the project using libreflex.a. (g++ -o myproj.exe -isystem..\RE-flex\include -L.\bin -lreflex myproj.cpp -g -std=c++20).

But still I am getting linker errors. I can't find any solution to this specific case. Please correct me where I gone wrong.
