Linker is unable to locate curl_global_init

Question

I am compiling a C++ application on Ubuntu 18.04. The linker is unable to pickup the required functions from the library or it is not locating the right library

I have libcurl.so located at /usr/local/lib

nm -D lists all the functions I need with T prefix . Yet when I compile as follows

g++ -std=c++17  -lcurl  tz.o main.o

I get

/usr/bin/ld: tz.o: in function 'date::curl_global()':
tz.cpp:(.text+0x9aef): undefined reference to 'curl_global_init'

I tried installing openssl-dev . No joy. So I uninstalled it.

Answer 1

try

g++ -std=c++17 tz.o main.o -lcurl

instead... g++ is shit in some ways, like argument ordering. (all i did was to make -lcurl the last argument instead of argument #3)
