CentOS 6.8 安装 R-3.5.0

1、系统环境 ：CentOS release 6.8 (Final)

2、安装包下载： wget https://cran.r-project.org/src/base/R-3/R-3.5.0.tar.gz

3、解压并安装：
tar xf R-3.5.0.tar.gz
./configure --enable-R-shlib=yes --with-tcltk --prefix=/usr/local/R
（报错）:
checking if bzip2 version >= 1.0.6... no

checking whether bzip2 support suffices... configure: error: bzip2 library and headers are required

（煎熬的过程从此开始，各种依赖，各种报错，R语言是不是不想让大家好好使用，真是服了。）

4、总结安装方法：
4.1 下载依赖包：
bzip2-1.0.6 wget http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
xz-5.2.2 wget http://tukaani.org/xz/xz-5.2.2.tar.gz
pcre-8.38 wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.38.tar.gz
curl-7.47.1 wget --no-check-certificate https://curl.haxx.se/download/curl-7.47.1.tar.gz

4.2 解压安装包：
tar xf bzip2-1.0.6.tar.gz -C /usr/local/
tar xf xz-5.2.2.tar.gz -C /usr/local/
tar xf pcre-8.38.tar.gz -C /usr/local/
tar xf curl-7.47.1.tar.gz -C /usr/local/
tar xf R-3.5.0.tar.gz -C /usr/local/

4.3 创建依赖包安装目录（上面所有的依赖包都要安装到这个目录，这一步很重要）
mkdir /usr/local/packages

4.4 首先安装依赖包，顺序不能乱
cd bzip2-1.0.6/
vim Makefile （修改Makefile，将第24行的CFLAGS=-Wall -Winline -O2 -g $(BIGFILES) 改为 CFLAGS=-fPIC -Wall -Winline -O2 -g $(BIGFILES)，就是在-Wall 前面加上-fPIC ）
make -f Makefile-libbz2_so
make clean
make
make install PREFIX=/usr/local/packages（）

 cd ../xz-5.2.2/
 ./configure --prefix=/usr/local/packages
 make -j4
 make install

 cd ../pcre-8.38/
 ./configure --enable-utf8 --prefix=/usr/local/packages
 make -j4
 make install

 cd ../curl-7.47.1/
 ./configure --prefix=/usr/local/packages
 make -j4
 make install

4.5 修改环境变量（根据实际安装路径修改）
export PATH=/usr/local/packages/bin:$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$LD_LIBRARY_PATH
export CFLAGS="-I/usr/local/packages/include"
export LDFLAGS="-L/usr/local/packages/lib"

4.6 安装R-3.5.0
cd ../R-3.5.0/
mkdir builddir
cd builddir/
mkdir /usr/local/packages/R-3.5.0
../configure --prefix=/usr/local/packages/R-3.5.0
make
make install
make pdf（生成packages的pdf帮助文档，若无linux无图形界面，则不需要进行此步骤）

修改环境变量 （根据实际安装路径修改）
echo 'export PATH=/usr/local/packages/R-3.5.0/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

4.7 测试
