kkaefer / load_curl.cpp

Last active May 28, 2018 12:15

Load cURL dynamically at runtime to avoid CURL_OPENSSL_3 vs. CURL_OPENSSL_4 symbol version mismatches

	#include <curl/curl.h>

	// Dynamically load all cURL functions. Debian-derived systems upgraded the OpenSSL version linked
	// to in https://salsa.debian.org/debian/curl/commit/95c94957bb7e89e36e78b995fed468c42f64d18d
	// They state:
	// Rename libcurl3 to libcurl4, because libcurl exposes an SSL_CTX via
	// CURLOPT_SSL_CTX_FUNCTION, and this object changes incompatibly between
	// openssl 1.0 and openssl 1.1.
	// Since we are not accessing the underlying OpenSSL context, we don't care whether we're linking
	// against libcurl3 or libcurl4; both use the ABI version 4 which hasn't changed since 2006
