gtk+ - błąd kompilacji w pierwszym programie.

Witam, chciałbym zainstalować gtk+ w code blocks.
Więc pobrałem paczkę, stworzyłem nowy projekt w cb i podałem ścieżkę do tej paczki.
Ale niestety moje plany pokrzyżowało coś takiego:

||More errors follow but not being shown.|

Chciałbym się dowiedzieć dlaczego tak się stało, skoro innym udało się to zrobić a u mnie nie...
Będę wdzięczny za pomoc w rozwikłaniu tego problemu.

Mam nadzieję że objętość pręgierza błędów nie zniechęciła Cię: zawsze naprawia się tylko pierwszy błąd, i kompiluje jeszcze raz.

Z tego co widzę wrzucasz nagłowki do folderu kompilatora. Jest to mało elegancka praktyka i powinno się w ustawieniach projektu określać dodatkowe ścieżki nagłówków/bibliotek.

Nie mam pojęcia o gtk+, ale odnoszę wrażenie, że błędnie nawigujesz się po folderach.
Mówiąc w miarę łopatologicznie:
Z podstawowego poziomu dołączania nagłówek gdk-pixbuf/gdk-pixbuf.h powinien być dostępny, u Ciebie natomiast w include jest jeden prawie-na-pewno zbędny podfolder gtk-2.0.
Jeśli brakuje Ci nagłówka zalokowanego w takim folderze to przeszukaj inne paczki developerskie.
