hello.c will use the header file plugin.h. If I want to use gcc to compile, can I know how should I write the -LXXX. gcc -o hello hello.c -LXXX
Currently my project structure look like this project directory is (C:\project) project
You don't link the header file, you include it. You link object files and static/shared libraries, which are already compiled files.
But to answer your question, you include your plugin with the -I option.
g++ -O2 examples/hello.c -I include/plugins -o hello
Or if you have a library to link say in lib:
g++ -O2 examples/hello.c -I include/plugins -L lib/plugins -lplugin -o hello
Or if you want to do in two steps (notice the -c)
g++ -O2 -c examples/hello.c -I include/plugins -o hello.o
g++ hello.o -L lib/plugins -lplugin -o hello
