Używam klasy Objective-C poniżej do indeksowania pliku Objective-C. Próbowałem parsować pliki, które używają zarówno #include jak i #import, z plikami nagłówków kątów i cudzysłowami. W żadnym wypadku nie zostanie wykonane wywołanie zwrotne ppIncludedFile. Clang wyraźnie zawiera pliki, ponieważ otrzymuję wywołania zwrotne dla symboli zdefiniowanych w nich. Ale jeśli chodzi o ogólną strukturę, otrzymuję enteredMainFile, wtedy otrzymam również startedTranslationUnit dla głównego pliku. Ale nigdy nie dowiedzieć się, jakie pliki nagłówek to patrząc wIndeksowanie pliku z clang-c nie trafia mojego wywołania zwrotnego ppIncludedFile
Zgodnie z dokumentacją.
/** * \ krótki Wywoływana, gdy plik trafia # włączone/# importowane. */
CXIdxClientFile (* ppIncludedFile) (CXClientData client_data, const CXIdxIncludedFileInfo *);
to się nie dzieje. Czy to błąd, czy też muszę coś zrobić, aby włączyć to oddzwanianie? Wersja libclang, której używam, pochodzi z rdzenia svn r156259.
