Question

我安装了libCurl，我正在尝试直接在Eclipse中从curl网站构建示例'simple.c'，但是我收到以下错误：

make all 
Building file: ../simple.c
Invoking: Cross GCC Compiler
gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"simple.d" -MT"simple.d" -o "simple.o" "../simple.c"
Finished building: ../simple.c

Building target: Test_SimpleCurl
Invoking: Cross GCC Linker
gcc  -o "Test_SimpleCurl"  ./simple.o   
Undefined symbols for architecture x86_64:
  "_curl_easy_cleanup", referenced from:
      _main in simple.o
  "_curl_easy_init", referenced from:
      _main in simple.o
  "_curl_easy_perform", referenced from:
      _main in simple.o
  "_curl_easy_setopt", referenced from:
      _main in simple.o
  "_curl_easy_strerror", referenced from:
      _main in simple.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Test_SimpleCurl] Error 1

这是Eclipse中一个简单的“新C ++项目＆gt;新文件”。构建时，Eclipse还会在调试文件夹中生成一些文件。这是'Makefile'的内容

-include ../makefile.init

RM := rm -rf

# All of the sources participating in the build are defined here
-include sources.mk
-include subdir.mk
-include objects.mk

ifneq ($(MAKECMDGOALS),clean)
ifneq ($(strip $(C_DEPS)),)
-include $(C_DEPS)
endif
endif

-include ../makefile.defs

# Add inputs and outputs from these tool invocations to the build variables 

# All Target
all: Test_SimpleCurl

# Tool invocations
Test_SimpleCurl: $(OBJS) $(USER_OBJS)
    @echo 'Building target: $@'
    @echo 'Invoking: Cross GCC Linker'
    gcc  -o "Test_SimpleCurl" $(OBJS) $(USER_OBJS) $(LIBS)
    @echo 'Finished building target: $@'
    @echo ' '

# Other Targets
clean:
    -$(RM) $(EXECUTABLES)$(OBJS)$(C_DEPS) Test_SimpleCurl
    -@echo ' '

.PHONY: all clean dependents
.SECONDARY:

-include ../makefile.targets

我会假设我缺少链接器或编译器标志，但我不知道在这个项目中添加这些标志的位置。

有什么建议吗？感谢

Eclipse上的libCurl C ++ - 未定义的符号
