c - New .h file in /usr/include linux

Question

I developed small c application in linux. For this application i placed .h file in linux standard path (/usr/include). Again i am compiling the same program

Output: FATA ERROR : xyz.h(my own header file) not found

Do i need to update any variable in gcc or way to solve this problem

Thank You

Answer 1

Place the header file in the same directory as your .c file and use -I. when compiling

gcc -I. main.c -o myprog

You shouldn't place your header files in /usr/include that is meant for the system headers.

Note: you don't actually need the -I. because the current directory is searched by default, nevertheless, it doesn't hurt to add it.
