Honored ContributorDear Kazu,
Finally I have solved the include path problem by setting path to C_INCLUDE_PATH. Thank for you help. However, it still gives these error. I have searched online for the solution. Maybe the project is not linked to the library. Then I tried to set some path to LD_LIBRARY_PATH. However, the error still there. I think I didn't set the correct library path. Do you know where should the library path of SD controller located? Will it be in the Project or Project_BSP folder? Or actually it's due to other problem? Thank you so much for you help.mun@ubuntu:~/Hello$ nios2-linux-gnu-gcc hello_world.c -o hello
