Perl5安装

由于CESM运行需要perl5，本来使用的是系统CentOS7自带的perl5，但版本较低，所以这里做一个升级，记录一下。

安装步骤

设置环境：

export CC=icc
export CXX=icpc
export CPP='icc -E'
export CXXCPP='icpc -E'
export CFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'
export CXXFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'
export CPPFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'
export F77=ifort
export FC=ifort
export FFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'
export FCLAGS='-O3 -xHost -ip -no-prec-div -static-intel'

解压源码压缩包

tar -xvf perl-5.38.2.tar.gz

进入源码文件夹

cd perl-5.38.2

./Configure -des -Dusethreads -Dprefix=/home/LIBRARIES/perl

make

make的时候遇到问题

参考Make error when compiling Perl 5.12.1 (RHEL 5.5)找到解决办法：

首先检查一下：

printenv C_INCLUDE_PATH
printenv CPATH

如果有路径输出则设置：

unset C_INCLUDE_PATH
unset CPATH

重新make继续安装可解决问题

make
make test
make install

make install 后设置环境变量：

export PATH=/home/LIBRARIES/perl/bin:$PATH
export LD_LIBRARY_PATH=/home/LIBRARIES/perl/lib/5.38.2:$LD_LIBRARY_PATH
export LIBRARY_PATH=/home/LIBRARIES/perl/lib/5.38.2:$LIBRARY_PATH
export PERL5LIB=/home/LIBRARIES/perl5/lib/perl5
export PERL_LOCAL_LIB_ROOT=/home/LIBRARIES/perl5
export PERL_MB_OPT="--install_base /home/LIBRARIES/perl5"
export PERL_MM_OPT="INSTALL_BASE=/home/LIBRARIES/perl5"

检查版本

perl --version

安装CESM运行必须的perl模块

安装cpanm

wget http://xrl.us/cpanm
chmod +x cpanm

记得改下cpanm里面的：

#!/usr/bin/env perl

改成你自己的目录：

#!/home/LIBRARIES/perl/bin/perl

安装App::cpanminus：

curl -L https://cpanmin.us | perl - App::cpanminus

或者使用

wget -O - https://cpanmin.us | perl - App::cpanminus

安装libxml2

# 下载源码压缩包
wget 'http://xmlsoft.org/sources/libxml2-2.9.10.tar.gz'
# 解压源码压缩包
tar -xf libxml2-2.9.10.tar.gz
# 进入源码文件夹
cd libxml2-2.9.10
./configure --prefix=/home/LIBRARIES/libxml2 --without-python
make
make install

安装cesm运行必须的perl模块

cpanm Alien::LibXML
cpanm Alien::Libxml2
# XML::LibXML依赖于 XML::SAX
cpanm XML::SAX
cpanm XML::LibXML

查看已经安装哪些perl模块

instmodsh
l
q
