cppcheck gives syntax error on "enum class"

[Lieven de Cock]

consider the following header file (it has been completely stripped from other stuff, and the library it belongs too could also be stripped away to reproduce the problem.

foo.h

#ifndef FOO_H
#define FOO_H

namespace Foo
{

enum class Mode
{
    readonly,
    readwrite
};

} // namespace Foo

#endif // FOO_H

call cppcheck (1.69) as :
cppcheck --verbose --enable=all --enable=style --xml -I"." foo.h

==>

<results> Checking foo.h... <error file="foo.h" line="7" id="syntaxError" severity="error" msg="syntax error"/> </results>

It gives an error on the enum class, remove the word class and the problem is gone.

By default cppcheck does not expect C++ code from a header file.
--language=c++ should fix that message.

According to this ticket, running cppcheck on .h files directly is not supported: http://trac.cppcheck.net/ticket/7383

Hi Daniel, Is this issue handled in latest release? i currently use cppcheck1.59 version. I could see similar error reported by cppcheck.

[Alexander Mai]

Please read the answers (and the ticket at trac) above to answer your question.

[Maarten Hoes]

The answer is: 'don't run cppcheck on .h files". So when running cppcheck on an entire project, how do you tell it to skip all the .h files completely ? I cannot find this piece of information on the manual, man page, or command help.

[Vladimir Liubimov]

The problem is cppcheck recognize content of the .h files as C language. You can force it to handle them as C++. Just pass the --language=c++ argument.

Cppcheck will normally skip the header files.

# recursively check all source files in folder (skip headers)
$ cppcheck folder
# check source files in visual studio solution
$ cppcheck --project=MyProject.sln
# check source files according to compile database
$ cppcheck --project=compile_commands.json
