Including header files recursively for syntastic

Question

I\'m working with a C++ project and trying to configure it to use syntastic. In my project I have a nested directory structure of header files (The actual nested structure is mu

Answer 1

I've had the same question with little luck. However, I've found that if I use the quotation mark style header includes, syntactic will appropriately check the folders and not issue warnings. For example, if you're working on foo2.cpp,

#include "dir3/foo4.h"
#include "../dir1/foo1.h"

Save bracket includes for standard libs and any libs you feel like hardcoding into vim.

Answer 2

You can include all the directories to be searched for header files per project in the project root directory in a file .syntastic_cpp_config. The format for doing so would the same as providing the -I directives to the compiler.

For your case it means:

• Create a file .syntastic_cpp_config under sources (assuming that's where your code is and sources is at a same depth level in the directory hierarchy as libs).

• Put the following lines in it:

  -Ilibs/dir1

  -Ilibs/dir2

  -Ilibs/dir2/dir3

• Note the the flags are 1 per line.

• This way you don't have to have all the include directories in your .vimrc.

You can have a different file to hold this custom configuration per project, specified by the .vimrc global variable g:syntastic_cpp_config_file, eg

let g:syntastic_cpp_config_file = '.my_custom_include_file_for_syntastic'

Syntastic will check each source directory and upwards until it finds this file and then use it for producing its output.
