When i'm compiling this code:
#include <iostream>
#include <curlpp/cURLpp.hpp>
#include <curlpp/Easy.hpp>
#include <curlpp/Options.hpp>
int main() {
cURLpp :: Cleanup cleanup;
std :: cout << "Hello world" << std :: endl;
return 0;
}
via console:
g++ main.cpp -lcurlpp
there are lot's of errors such as:
/usr/lib/gcc/x86_64-linux-gnu/4.9/../../../x86_64-linux-gnu/libcurlpp.so: undefined reference to `curl_getenv@CURL_OPENSSL_3'
which are connected only with CURL_OPENSSL_3
How can i fix it? Thanks
Ubuntu 15.04, curl version - 7.38.00, curlpp - installed sudo apt-get install libcurlpp-dev
On Mint 17 I was able to compile and run your program using
g++ main.cpp -lcurl -lcurlpp
Looking at a library dump of the program, you may be missing the following libraries which you can install with apt-get:
