undefined reference to curl_global_init, curl_easy_init and other function(C)
In addition to Joachim Pileborg's answer, it is useful to remember that gcc/g++ linking is sensitive to order and that your linked libraries must follow the things that depend upon them.
$ gcc -lcurl test.c
will fail, missing the same symbols as before. I mention this because I came to this page for forgetting this fact.
I have the same problem, but i use g++ with a make file.This is a linker issue.You need to add option -lcurl on the compiler and on the linker.In my case on the make file:
CC ?= gccCXX ?= g++CXXFLAGS += -I ../src/ -I ./ -DLINUX -lcurl <- compile optionLDFLAGS += -lrt -lpthread -lcurl <- linker option
