./configure 不懂?

在安装zlib时做./configure时出现下类出错信息,请问这是什么问题啊
root# ./configure   
Checking for gcc...
Building static library libz.a version 1.2.1 with cc.
Checking for unistd.h... No.
Checking whether to use vs[n]printf() or s[n]printf()... using s[n]printf()
Checking for snprintf() in stdio.h... No.
  WARNING: snprintf() not found, falling back to sprintf(). zlib

  vulnerabilities.

什么叫 string-format security  ?

不行的,下一步make的时候显示如下信息:
root# make
gcc -fast -xcg89 -DNO_snprintf -DHAS_sprintf_void -DNO_ERRNO_H  -c  example.c
sh: gcc: not found
*** Error code 1
make: Fatal error: Command failed for target `example.o'



进行不下去的

race

sh: gcc: not found
gcc的路径没设置对
