main.cc:5:30: fatal error: folder/file.h: No such file or directory
c++, makefile, ubuntu
Solution
This depends a bit on your C compiler, but "typically" when you include a file using the `< ... >` syntax the compiler will only look for those header files in directories you have specified on the command line with the `-I` flag, plus various built-in system directories.
Notably, it usually will not look in the current working directory, unless you explicitly add `-I.` to the compile line.
Alternatively, if you use the `" ... "` form of `#include`, then it will look in the current working directory as well.
So, either switch to `#include "folder/file.h"`, or else add `-I.` to your compile line.
Problem
When I use type `make` into Ubuntu terminal I get: ``` main.cc:5:30: fatal error: folder/file.h: No such file or directory ``` The folder exists in the working directory and the file.h exists in the specified folder. When I type `ls` it lists the folder and file in my working directory as well. Oddly enough, when I open it in geany and ask it to find the file in the ``` #include <folder/file.h> ``` it finds it without issue but when it builds it I get the error. Is there a flag I need to set so it so it includes the folder? If so, what would that look like exactly?
