I want to compile wkhtmltopdf on Ubuntu Server, but I have a problem with following errors:

/usr/lib/libQtGui.so: undefined reference to `png_read_info@PNG12_0'
/usr/lib/libQtGui.so: undefined reference to `png_set_gAMA@PNG12_0'
/usr/lib/libQtGui.so: undefined reference to `png_set_PLTE@PNG12_0'
...
/usr/lib/libQtGui.so: undefined reference to `png_create_info_struct@PNG12_0'
/usr/lib/libQtGui.so: undefined reference to `png_set_bgr@PNG12_0'
/usr/lib/libQtGui.so: undefined reference to `png_get_valid@PNG12_0'
