I use Gio::FileEnumerator to tranverse each file in a directory,but the
call of FileEnumertator::next_file() failed during execution,why?
Glib::RefPtr<Gio::File> file=Gio::File::create_for_path ("./data");
Glib::RefPtr<Gio::FileEnumerator> fileEnum=file->enumerate_children();
Glib::RefPtr<Gio::FileInfo> fileInfo;
while((fileInfo=fileEnum->next_file())!=NULL) //failed
{
Glib::ustring filename="./data"+"/"+fileInfo->get_name();
Glib::ustring suffix=filename.substr(filename.size()-3,3);
if(suffix=="jpg" || suffix=="bmp" || suffix=="png")
filenameArray.push_back(filename);
}
gdb result:
glibmm-WARNING **: Failed to wrap object of type 'GLocalFileEnumerator'.
Hint: this error is commonly caused by failing to call a library init()
function.
Program received signal SIGSEGV, Segmentation fault.
