如何在Linux编译32位库
来源: 互联网 发布时间:2017-02-05
本文导语: 大家好! 我现在有一个cent os 64位的系统,想编译一个32位的静态库,该如何编译呢?我要编译的代码如下: code.google.com/p/spserver ,求大侠指点如何修改这里面的makefile文件 以下是makefile全文: #-------------------...

如果CentOS支持multilib,那么在CFLAGS里加上-m32即可
|
先检测你的gcc,是否支持-m32
支持的话,CFLAGS = $(CFLAGS) -m32
不支持的话,要重新折腾个gcc了

CentOS 64位还得先装32位的运行时库吧
