Thanks guys for the help. I tried linking statically as described below and it did produce a static library; however, it is still crashing. It is crashing here in asyn-thread.c when it is trying to free the hostname.
/* * destroy_async_data() cleans up async resolver data and thread handle. */ static void destroy_async_data (struct Curl_async *async) { if(async->hostname) free(async->hostname); <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< if(async->os_specific) { struct thread_data *td = (struct thread_data*) async->os_specific; if(td->thread_hnd != curl_thread_t_null) Curl_thread_join(&td->thread_hnd); destroy_thread_sync_data(&td->tsd); free(async->os_specific); } async->hostname = NULL; async->os_specific = NULL; } Here is how I set the hostname (URL) in my code curlStatus = curl_easy_setopt(m_hCurl, CURLOPT_URL, szURL) where szURL is a local char* variable. any help would be greatly appreciated :) I've been stuck on this thing for 2 weeks now.
