here is my problem
these days i 'm doing some research with other's code,it's for the linux,
in his code ,he defined a class named ImageLoader,
which worked fine , but i need to transplant it to the windows,lots of problems comes up,
and now ,my problem is eachtime i run the program , there will be an access violatin happened,
i found the violation point is this member function , read(filename),i don't know how to debug this dll further,
i will appreciate it if you can tell me what to do ,THX !!!!!!
here is his original code :
Code: Select all
bool ImageLoader::LoadImage(const string& filename,
Image* out_image, string* out_filename) const {
assert(out_image != NULL);
assert(out_filename != NULL);
cout<<filename<<endl;
out_image->read(filename); //here is the point of an access violation happened
cout<<"t+1"<<endl;
if (AcceptsFormat(out_image->magick())) {
*out_filename = filename;
return true;
} else {
out_image->magick(preferred_format_);
char temp_file_name[1024];
sprintf(temp_file_name, "D:\\tmp\\libpmk_loader.%d.XXXXXX", getpid());
mktemp(temp_file_name);
out_image->write(temp_file_name);
*out_filename = temp_file_name;
return false;
}
}Code: Select all
