無法構建zpipe.c（Zlib示例程序）

Question

我正在嘗試構建zpipe.c。我已經通過配置安裝了zlib 1.2.5;使;進行安裝。 我已將我的zpipe.c文件移動到其包含zlib.h頭文件的實際zlib-1.2.5目錄中。

這是我所得到的，當我嘗試建立：

[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' 

自述好好嘗試一下說具體談談構建在Linux上任何東西，我看到deflate.h和其他.h文件都位於在目錄...

源頭上zpipe.c是在這裏：http://www.zlib.net/zpipe.c

任何想法？ TIA

問題不在頭文件中，它編譯得很好。問題是鏈接器找不到庫函數。試着用這個編譯：

gcc zpipe.c -lz 

這將libz.a或libz.so（取決於你是否是靜態或動態編譯）編譯，如果正確的話，這些目標文件應包含缺少的功能。
