# 錯誤1-實際上是缺少readline-devel
configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.
#錯誤2-查看依賴 yum search zlib
configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-zlib to disable zlib support.
