Re: building from urlwrite gives undefined reference to `_errno()' (MinGW build 3.3.50+)

[Tatsuro MATSUOKA]

Hello

In urlwrite, I found 

  std::string lasterror (void) const
    {
      CURLcode errno;

      curl_easy_getinfo (rep->handle(), CURLINFO_OS_ERRNO, &errno);
      
      return std::string (curl_easy_strerror (errno));
    }

Perhaps the link error comes from curl library I am using.

Regards

Tatsuro
