Question

我正在尝试构建zpipe.c。我通过configure安装了zlib 1.2.5;使; make install。我已将zpipe.c文件移动到实际的zlib-1.2.5目录中，其中包含zlib.h头文件。

这是我在尝试构建时得到的结果：

[sk@lldma zlib-1.2.5]$ gcc zpipe.c 
/tmp/ccZ2OBz0.o: In function `def':
zpipe.c:(.text+0x3c): undefined reference to `deflateInit_'    
zpipe.c:(.text+0x8f): undefined reference to `deflateEnd'
zpipe.c:(.text+0xe2): undefined reference to `deflate'
zpipe.c:(.text+0x163): undefined reference to `deflateEnd'
zpipe.c:(.text+0x1df): undefined reference to `deflateEnd'
/tmp/ccZ2OBz0.o: In function `inf':
zpipe.c:(.text+0x22d): undefined reference to `inflateInit_'
zpipe.c:(.text+0x280): undefined reference to `inflateEnd'
zpipe.c:(.text+0x2c1): undefined reference to `inflate'
zpipe.c:(.text+0x312): undefined reference to `inflateEnd'
zpipe.c:(.text+0x36e): undefined reference to `inflateEnd'
zpipe.c:(.text+0x398): undefined reference to `inflateEnd'

自述文件没有说明在Linux上构建的具体内容，我看到deflate.h和其他.h文件都位于目录中......

zpipe.c的源代码在这里：http://www.zlib.net/zpipe.c

有什么想法吗？ TIA

问题不在标题中，它编译得很好。问题是链接器无法找到库函数。尝试编译：

gcc zpipe.c -lz

这将使用libz.a或libz.so进行编译（取决于您是静态编译还是动态编译），如果正确，这些目标文件应包含缺少的函数。

无法构建zpipe.c（Zlib示例程序）
