zlib-1.2.3 64位安装

/usr/bin/ld: /usr/local/lib/libz.a(crc32.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC

/usr/local/lib/libz.a: could not read symbols: Bad value

一般是64 位 电脑才会出现。

解决方法如下：

cd zlib-1.2.3 //进入zlib目录

CFLAGS="-O3 -fPIC" ./configure //使用64位元的方法进行编译

make

make install

make clean

上面操作演示结果如下：

[root@unix-server1 zlib-1.2.3]# CFLAGS="-O3 -fPIC" ./configure --prefix=/usr/local/zlib/
