Everything is ok
Code 'namespacedummy{' is invalid C code. Use --std or --language to configure the language.".

Sub Category: syntaxError

Please provide any additional information below.
Looks like cppcheck tries to check the .h file as C language instead of C++ as it thinks that the valid c++ keyword "namespace" is invalid. The bot should have an option to add --std or --language.
