i compiled this sample code:
#include <stdio.h>
#include <curl/curl.h>

int main(void)
  CURL *curl;
  CURLcode res;
  curl = curl_easy_init();
  if(curl) {
     curl_easy_setopt(curl, CURLOPT_URL, "");
     res = curl_easy_perform(curl);
     /* always cleanup */
   return 0;

debugger output:

whats wrong with wsock32 library?

here my makefile:
# Project: Projekt1

CPP = g++.exe -D__DEBUG__
CC = gcc.exe -D__DEBUG__
WINDRES = windres.exe
OBJ = main.o $(RES)
LINKOBJ = main.o $(RES)
LIBS = -L"C:\c++\mingw\lib" -L"C:/c++/curl/lib" -L"C:\C++\openssl\lib"
-lcurl -lssl -lcrypto -lwsock32 -lgdi32 -lwinmm
INCS = -I"C:\c++\mingw\include" -I"C:/c++/curl/include"
CXXINCS = -I"C:/c++/curl/include"
BIN = Projekt1.exe
RM = del

.PHONY: all all-before all-after clean clean-custom

all: all-before Projekt1.exe all-after

clean: clean-custom
        ${RM} $(OBJ) $(BIN)

$(BIN): $(OBJ)
        $(CPP) $(LINKOBJ) -o "Projekt1.exe" $(LIBS)

main.o: main.cpp
        $(CPP) -c main.cpp -o main.o $(CXXFLAGS)

any idea?
