Configuration file look up doesn't work since commit 6d7c0b3

[betonniere]

Since commit 6d7c0b3 Security: clear defaults for config file names (cf. #2170). syntastic_<file_type>_config files (syntastic_cpp_config in my case) are ignored.

Please explain what did you do, what did you expect to happen, and what happened instead.

In this tarball you can find a main.cpp file including b.hpp (#include "b.hpp") located in a different folder. To instruct syntastic where to find included files, I've dropped a configuration file (.syntastic_cpp_config) with a -Ib directive in the root folder:

Bug2179
├── a
│   └── main.cpp
├── b
│   └── b.hpp
└── .syntastic_cpp_config

From commit 6d7c0b3, syntastic gets confused and display a syntax error in the Vim's location list:

fatal error: b.hpp: No such file or directory

while this false alert isn't raised prior to this commit.

After the commit you mention the name .syntastic_cpp_config is no longer "magic", you need to set syntastic_cpp_config_file explicitly to the name of the configuration file. To avoid the security problem you are strongly advised to use a different name than .syntastic_cpp_config.

Ok, got it. Your suggestion works.
Sorry for the inconvenience.
