I'm fairly new to C and writing makefiles. I'm trying to compile a C project with the "canonical" structure described here with a makefile. I'm running into a problem where the compilation is failing because it can't find the headers due to using <brackets> instead of "quotes" when including the headers.

How do I tell the compiler where to find the headers in the project?

CodePudding user response：

Usually, you would use the -I option, followed by a relative or absolute path to the directory where the headers are.

For example:

gcc -c src/foo.c -o obj/foo.o -I src

(However, compiler options are not part of the C standard, so it depends on what compiler you are using, and you did not say.)
