It looks quite easy to find such a tool for Java (Checkstyle, JCSC), but I can't seem to find one for C/C++. I am not looking for a lint-like static code analyzer, I only would like to check against coding standards like variable naming, capitalization, spacing, identation, bracket placement, and so on.
I'm sure this could help to some degree cxx checker. Also this tool seems to be pretty good KWStyle It's from Kitware, the guys who develop Cmake.
Not exactly what you ask for, but I've found it easier to just all agree on a coding standard astyle can generate and then automate the process.
Try nsiqcppstyle. It's a Python based coding style checker for C/C++. It's easy to extend to add your own rules.
