#576 Add case sensitivity for header/source search under case-sensitive systems

[TSM]

For instance, all FLTK headers end with .H and not .h. That makes it impossible for parser to detect those files on GNU/Linux and similar OSes.
Adding "H" into extension list manually doesn't help.

Can you provide more details about the problem?
Because there are plenty of places where headers/sources are searched and it is not clear from your explanation what exactly are you talking about.

[TSM]

It should be easy to reproduce: just create two header files in one of directories defined in the compiler search path (e.g. /usr/include), one with .H extension and another one with .h, make some definitions in them and reparse the project.
You should see that #include autocompletion works with .h file but not with .H; also, if you include .H header manually, code completion won't finish definitions from it.

Some related discussion here: wxFileExists/wxDir::GetAllFiles difference; does this inconsistency is filesystem relative or not?

I just check the CC plugin parser's code, see that it use this function:

wxArrayString ParserBase::FindFileInIncludeDirs(const wxString& file, bool firstonly)
{
    wxArrayString FoundSet;
    for (size_t idxSearch = 0; idxSearch < m_IncludeDirs.GetCount(); ++idxSearch)
    {
        wxString base = m_IncludeDirs[idxSearch];
        wxFileName tmp = file;
        NormalizePath(tmp,base);
        wxString fullname = tmp.GetFullPath();
        if (wxFileExists(fullname))
        {
            FoundSet.Add(fullname);
            if (firstonly)
                break;
        }
    }

    TRACE(_T("ParserBase::FindFileInIncludeDirs(): Searching %s"), file.wx_str());
    TRACE(_T("ParserBase::FindFileInIncludeDirs(): Found %lu"), static_cast<unsigned long>(FoundSet.GetCount()));

    return FoundSet;
}
