我正在尝试在这里构建源代码,以便我可以开始为自己修改它

http://curl.haxx.se/libcurl/c/ftpget.html

我下载文件,然后运行

gcc -o test ftpget.c

得到

Undefined symbols:
  "_curl_global_init",referenced from:
      _main in ccFchguB.o
  "_curl_easy_perform",referenced from:
      _main in ccFchguB.o
  "_curl_easy_setopt",referenced from:

  "_curl_global_cleanup",referenced from:
      _main in ccFchguB.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

这对我没有意义,因为

/usr/local/include/curl/curl.h

存在并具有这些功能.我确定这是我遗漏的一些基本的c编译.

非常感谢任何指针.
