[Solved] libcurl – unable to download a file

by


Your code

    curl_easy_setopt(handle,CURLOPT_WRITEFUNCTION,&AZLyricsDownloader::write_data_to_var);

and the following quote from the documentation from libcurl

There’s basically only one thing to keep in mind when using C++
instead of C when interfacing libcurl:

The callbacks CANNOT be non-static class member functions

Example C++ code:

class AClass { static size_t write_data(void *ptr, size_t size, size_t nmemb, void* ourpointer) { /* do what you want with the data */ } }

could be the source of your problem as your function is not a static member. Even if not you are breaking this rule.

This may not solve your problem but given the amount of code you have posted in your example, that was the first thing that immediately came to mind and it is worth changing this as recommended by libcurl. If it does not solve your problem I would suggest identifying the error you are getting in more detail so that you can pose a more specific question next time (with a lot less code displayed).
