loongnixserver安装lzo

第一步：首先安装编译环境
yum -y install gcc-c++ lzo-devel zlib-devel autoconf automake libtool make
第二步：下载源码包并解压
wget http://www.oberhumer.com/opensource/lzo/download/lzo-2.10.tar.gz
tar -zxvf lzo-2.10.tar.gz
cd lzo-2.10/

编译后可能会遇到以下错误，出现错误的原因是源码中缺少对龙芯loongarch架构的支持：

configure: Configuring LZO 2.10
checking build system type... autoconf/config.guess: unable to guess system type

This script (version 2017-02-07), has failed to recognize the
operating system you are using. If your script is old, overwrite
config.guess and config.sub with the latest versions from:

  http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess
and
  http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub

If autoconf/config.guess has already been updated, send the following data and any
information you think might be pertinent to config-patches@gnu.org to
provide the necessary information to handle your system.

config.guess timestamp = 2017-02-07

uname -m = loongarch64
uname -r = 4.19.190-2.lns8.loongarch64
uname -s = Linux

/usr/bin/uname -p = loongarch64
/bin/uname -X     = 

hostinfo               = 
/bin/universe          = 
/usr/bin/arch -k       =

/usr/bin/oslevel       =

configure: error: cannot guess build type; you must specify one

　　解决以上错误需要修改以下两个文件，在编译配置中增加对loongarch的支持：

第一个：autoconf/config.guess

[root@localhost lzo-2.10]# cd autoconf/
[root@localhost autoconf]# vi config.guess

在行476下添加对loongarch架构的支持：
loongarch64:*:*)
   echo loongarch64
   4exit ;;

在行1000下添加对loongarch64下系统的支持：
loongarch64:Linux:*:*)
  echo ${UNAME_MACHINE}-unknown-linux-${LIBC}
  exit ;;

保存：
：wq

　第二个：autoconf/config.sub

[root@localhost autoconf]# vi config.sub 
在行274下增加CPU的支持语句：
| loongarch64 \
在行400下增加cpu类型的说明：
| loongarch64-* \

保存：
：wq

　　完成以下修改后重新进行配置和编译：

重新配置：
./configure -enable-shared -prefix=/opt/hadoop/lzo/
# 开始编译安装
make 
make install

　　编译成功后，可以在/opt/hadoop/lzo/看到生成编译后的文件
