使用 zLib 放气和充气时出错

Question

我正在尝试使用 gcc 在我的 Linux(Ubuntu 8.04) 中编译 zpipe.c 示例，但出现了一些错误，请查看：

[ubuntu@eeepc:~/Desktop] gcc zpipe.c
/tmp/ccczEQxz.o: In function `def':
zpipe.c:(.text+0x65): undefined reference to `deflateInit_'
zpipe.c:(.text+0xd3): undefined reference to `deflateEnd'
zpipe.c:(.text+0x150): undefined reference to `deflate'
zpipe.c:(.text+0x1e8): undefined reference to `deflateEnd'
zpipe.c:(.text+0x27b): undefined reference to `deflateEnd'
/tmp/ccczEQxz.o: In function `inf':
zpipe.c:(.text+0x314): undefined reference to `inflateInit_'
zpipe.c:(.text+0x382): undefined reference to `inflateEnd'
zpipe.c:(.text+0x3d7): undefined reference to `inflate'
zpipe.c:(.text+0x44b): undefined reference to `inflateEnd'
zpipe.c:(.text+0x4c1): undefined reference to `inflateEnd'
zpipe.c:(.text+0x4f6): undefined reference to `inflateEnd'
collect2: ld returned 1 exit status

记得我已经正确安装了 zLib-dev，但是为什么会出现这个错误？

您还需要将它与 zlib 库链接。只需将 -lz 添加到命令行的末尾即可。
