flymake: Getting the include directories
5.4 Getting the include directories
===================================
Two sets of include directories are distinguished: system include
directories and project include directories. The former is just the
contents of the ‘INCLUDE’ environment variable. The latter is not so
easy to obtain, and the way it can be obtained can vary greatly for
different projects. Therefore, a customizable variable
‘flymake-get-project-include-dirs-function’ is used to provide the way
to implement the desired behavior.
The default implementation, ‘flymake-get-project-include-dirs-imp’,
uses a ‘make’ call. This requires a correct base directory, that is, a
directory containing a correct ‘Makefile’, to be determined.
As obtaining the project include directories might be a costly
operation, its return value is cached in the hash table. The cache is
cleared in the beginning of every syntax check attempt.
