Я получаю ошибку при компиляции qvfb для x11.Ошибка компиляции qvfb - неопределенная ссылка на `png_create_write_struct '
1> Теперь, где это png_create_write_struct объявляется, что я получаю ошибки, связанные с ним ?
2> Есть ли qvbf компиляция для x11 ищет Libpng в файловой системе хоста или он ищет Libpng внутри QT_source_code ?
3> Пожалуйста, предложите Как устранить эту ошибку компиляции успешно ?

===================== ======== EDIT =================
Спасибо всем, что он работает.
создания произведения: мягкое ссылка -
пер -s /lib/i386-linux-gnu/libpng12.so.0 /lib/i386-linux-gnu/libpng.so
это работает: - -
-L/Библиотека/i386-Linux-гну -lpng
Также вы можете напрямую изменить свой qvfb.pro файл, вместо того, чтобы непосредственно в командной строке: --- ЛИЭС = -L/Библиотека/i386-linux-gnu -lpng
, пожалуйста, предложите по этому вопросу любую помощь будет заметна. !! – Katoch
