Invalid "... not found in any directly included header"

[pmconrad]

Maybe I'm doing something wrong, but I don't see what that might be. :-/

Simple test:

• create /tmp/include/test/inc.hpp with this:

#pragma once

#include <vector>
#include <string_view>

namespace test {
        std::vector<char> from_hex(const std::string_view& in);
}

• create /tmp/src/test/hex.cpp with this:

#include <test/inc.hpp>

namespace test {
        std::vector<char> from_hex(const std::string_view& in) {
                std::vector<char> result;
                result.reserve(in.size() / 2 + 1);
                return result;
        }
}

• g++ --std=c++17 -Wall -I /tmp/include/ -c -o /tmp/src/test/hex.o /tmp/src/test/hex.cpp works without warnings
• But cppclean --include-path=/tmp/include /tmp/src/ complains

/tmp/src/test/hex.cpp:4: 'from_hex' not found in any directly #included header

What am I missing?

I ran into the same problem. I found that it was caused by including with angle-brackets instead of double quotes. I found two solutions:

1. Change all angle-bracket includes like #include <mylib/my_file.hpp> to double quotes like #include "mylib/my_file.hpp", or
2. Use the --include-path-non-system option of cppclean: cppclean --include-path-non-system=/tmp/include /tmp/src/

Thanks. I think at the very least the error message is misleading.
