c - hiredis "undefined reference to"编译错误

Question

我想用 C 编译 redis 的客户端。我已经下载并安装了 libevent 库和 hiredis 文件。我用过这个命令:

gcc -I/home/tasos/Dropbox/lists/hiredis example-libevent.c -levent

但我得到这些错误:

/tmp/ccxoerYJ.o: In function `redisLibeventReadEvent':
example-libevent.c:(.text+0x28): undefined reference to `redisAsyncHandleRead'
/tmp/ccxoerYJ.o: In function `redisLibeventWriteEvent':
example-libevent.c:(.text+0x56): undefined reference to `redisAsyncHandleWrite'
/tmp/ccxoerYJ.o: In function `getCallback':
example-libevent.c:(.text+0x2d2): undefined reference to `redisAsyncDisconnect'
/tmp/ccxoerYJ.o: In function `main':
example-libevent.c:(.text+0x393): undefined reference to `redisAsyncConnect'
example-libevent.c:(.text+0x3f3): undefined reference to `redisAsyncSetConnectCallback'
example-libevent.c:(.text+0x404): undefined reference to `redisAsyncSetDisconnectCallback'
example-libevent.c:(.text+0x45d): undefined reference to `redisAsyncCommand'
example-libevent.c:(.text+0x47d): undefined reference to `redisAsyncCommand'
collect2: ld returned 1 exit status

为什么这不起作用？

在命令中使用-levent 和-lhiredis 编译选项。
