新手请教一个cc编译问题，不用－g可以，用了-g就报错？

cc -o -g  test test.c tool.c -lcurses -lisam

我该怎么办，上面的字符我的test.c里面都没有啊？

－g 在编译出可执行档时，附加执行时除错资讯，以供 gdb 读取
错误提示：×××多重定义

编译命令语句错了！正确的应该是
cc -g -o test test.c tool.c -lcurses -lisam

万分感谢，原来参数换以下位置就好了，谢谢！

不是参数换位置的问题,而是因为有的选项"-x" 有子选项,他们不能分开写.
比如"-o test" 是一个整体,表示最终编译生成的可执行文件叫test.

只要理解每个参数代表的意思就不会犯这样的错了.
