Linux 下 R 源码安装指南

本文主要是介绍Linux 下 R 源码安装指南，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

📢 本文章同步自作者的语雀知识库，请点击这里阅读原文。

如果你使用的 Linux 系统 GCC 版本太低, 又没有 root 权限 (即使有 root 权限又担心升级 GCC 带来的风险) ; 同时你又不想入坑 conda, 但是你又希望安装一个最新版本的 R, 那么恭喜你, 这篇普通用户在 Linux 下源码编译安装 R 的记录刚好满足了你想要的一切.。

📢 说明

本文档以 R-3.6.0 为例, 但对于 R-3.6.x, R-4.0.x 的安装同样适用。

根据本教程，经过测试，以下版本均可以正常安装成功。

R-4.0.3

R-4.1.2

R-4.3.0

本教程在以下的安装环境中，经过测试都可以正常操作：

系统（版本）	GCC 版本
Red Hat Enterprise Linux Server release 6.5 (Santiago), x86_64	gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)
CentOS Linux release 7.6.1810 (Core), x86_64	gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)
openEuler 20.03 (LTS)	gcc (GCC) 7.3.0

1. 安装命令

R 源码编译安装基本命令。

# Rpy：--enable-R-shlib
# download list：https://mirrors.ustc.edu.cn/CRAN/src/base/
$ wget https://mirrors.ustc.edu.cn/CRAN/src/base/R-3/R-3.6.0.tar.gz 
$ tar zxvf R-3.6.0.tar.gz
$ cd R-3.6.0
$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0  --enable-R-shlib --enable-BLAS-shlib  --with-blas   --with-lapack

关于 R 相关的动态库：

R 编译的过程中，如果想要在其他语言中集成 R 就必须选择--enable-R-shlib选项，将 R 编译成 lib 模式，在此模式下，会生成 path-to-R/lib/libR.so库——将 R 编译成动态库(libR.so)，然后 R 的执行程序与之链接；
- 例如，如果不编译生成 libR.so，在安装 rpy2（Python 中的 R 语言接口模块）时就无法正确编译。
同时，确保同目录下 libRblas.so,libRlapack.so 两个链接库也被正确生成，这两个库默认会生成，如果没有，需要添加参数：--enable-BLAS-shlib,--with-blas,--with-lapack；

2. 基础环境

configure: error: No Fortran compiler found

# Ubuntu/Debian
apt install gfortran

# RHEL/openEluer
yum install gcc-gfortran

configure: error: C++ preprocessor "/lib/cpp" fails sanity check

# Ubuntu/Debian
apt install build-essential
apt install g++

# RHEL/openEluer
yum install glibc-headers
yum install gcc-c++

3. 各种库和依赖解决

R 源码编译安装的时候需要的各种依赖库比较多，如果你有 root 的权限，建议使用 yum/apt 等系统命令解决；如果没有 root 权限，可以手动一个个去解决。

3.1 自动处理

针对 RHEL/Debian 一些常见的依赖，使用 yum/apt 自动解决的示例。

configure: error: --with-readline=yes (default) and headers/libs are not available

# Ubuntu/Debian
apt install install libreadline-dev

# RHEL/openEluer
yum install readline-devel

configure: error: --with-x=yes (default) and X11 headers/libs are not available

# Ubuntu/Debian
apt install libx11-dev xorg-dev libcurl4-openssl-dev

# RHEL/openEluer
yum install xorg-x11-server-devel libX11-devel libXt-devel

configure: error: "liblzma library and headers are required"

# Ubuntu/Debian
apt install liblzma-dev

# RHEL/openEluer
yum install lzma-devel xz xz-devel

configure: error: PCRE2 library and headers are required, or use --with-pcre1 and PCRE >= 8.32 with UTF-8 support

# Ubuntu/Debian
apt install libpcre2-dev

# RHEL/openEluer 
yum install pcre pcre-devel			# 安装 PCRE1
yum install pcre2 pcre2-devel		# 安装 PCRE2

configure: error: libcurl >= 7.28.0 library and headers are required with support for https

# Ubuntu/Debian
apt install libcurl4-openssl-dev

# RHEL/openEluer 
yum install libcurl-devel

JPEG

R 安装过程中默认开启 --with-jpeglib（use jpeglib library (if available) [yes]），但是相关的依赖没有，依然可以正常安装（没有任何报错），但最后会提示：Capabilities skipped: JPEG！

# Ubuntu/Debian
yum install libjpeg-dev

# RHEL/openEluer 
yum install libjpeg-devel

TIFF

R 安装过程中默认开启 --with-tifflib（use libtiff library (if available) [yes]），但是相关的依赖没有，依然可以正常安装（没有任何报错），但最后会提示：Capabilities skipped: TIFF！

# Ubuntu/Debian
yum install libtiff-dev

# RHEL/openEluer 
yum install libtiff-devel

cairo

R 安装过程中默认开启 --with-cairo（use cairo (and pango) if available [yes]），但是相关的依赖没有，依然可以正常安装（没有任何报错），但最后会提示：Capabilities skipped: cairo！

# Ubuntu/Debian
apt install libcairo2-dev libxt-dev

# RHEL/openEluer 
yum install cairo-devel

ICU

R 安装过程中默认开启 --with-ICU（use ICU library (if available) [yes]），如果不可用，最后会提示：Capabilities skipped: ICU！

# Ubuntu/Debian
apt install libicu-dev

# RHEL/openEluer 
yum install libicu libicu-devel

3.2 手动处理

以下是一些常见的依赖手动解决的示例，可以参考。

zlib

根据《R Installation and Administration: A.1 Essential programs and libraries》官方文档，zlib (version 1.2.5 or later)，至少需要 1.2.5 及以上版本。

Installations ofzlib(version 1.2.5 or later), libbz2(version 1.0.6 or later: called bzip2-libs/bzip2-devel or libbz2-1.0/libbz2-dev by some Linux distributions) andliblzmaversion 5.0.3 or later are required.

报错：
checking for zlib.h... yes
checking if zlib version >= 1.2.5... no
checking whether zlib support suffices... configure: error: zlib library and headers are required  
## 缺少zlib或者zlib版本过低, 要求 zlib 版本 >= 1.2.5

# download list：http://www.zlib.net/fossils/
$ wget http://www.zlib.net/fossils/zlib-1.2.6.tar.gz
$ tar xvf zlib-1.2.6.tar.gz
$ cd zlib-1.2.6
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/zlib-1.2.6
$ make && make install

接着安装 R-3.6.0:

$ cd ../R-3.6.0
$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0  --enable-R-shlib LDFLAGS="-L/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/lib" CPPFLAGS="-I/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/include"

    报错：
    checking for zlib.h... yes
    checking if zlib version >= 1.2.5... yes
    checking whether zlib support suffices... yes
    checking mmap support for zlib... yes
    checking for BZ2_bzlibVersion in -lbz2... yes
    checking bzlib.h usability... yes
    checking bzlib.h presence... yes
    checking for bzlib.h... yes
    checking if bzip2 version >= 1.0.6... no
    checking whether bzip2 support suffices... configure: error: bzip2 library and headers are required
    ## zlib 版本已经符合要求，bzip2 版本要求 >= 1.0.6

bzip2 or libbz2

根据《R Installation and Administration: A.1 Essential programs and libraries》官方文档, libbz2 (version 1.0.6 or later: called bzip2-libs/bzip2-devel or libbz2-1.0/libbz2-dev by some Linux distributions)，至少需要 1.0.6 及以上版本.

$ wget http://www.bzip.org/1.0.6/bzip2-1.0.6.tar.gz
$ tar zvxf bzip2-1.0.6.tar.gz
$ cd bzip2-1.0.6
$ make -f Makefile-libbz2_so
$ make clean
$ make
$ make install PREFIX=/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6

重新安装 R-3.6.0:

$ cd ../R-3.6.0
$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0  --enable-R-shlib LDFLAGS="-L/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/lib -L/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/lib" CPPFLAGS="-I/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/include -I/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/include"

    报错：
    checking if bzip2 version >= 1.0.6... yes
    checking whether bzip2 support suffices... yes
    checking for lzma_version_number in -llzma... yes
    checking lzma.h usability... yes
    checking lzma.h presence... yes
    checking for lzma.h... yes
    checking if lzma version >= 5.0.3... yes
    checking for pcre_fullinfo in -lpcre... no
    checking whether PCRE support suffices... configure: error: pcre >= 8.10 library and headers are required
    ## 要求 pcre >= 8.10 (同时要求 pcre < 10.0, 否则再次安装 R-3.6.0 时报错)
    
    # 安装 pcre-8.12，configure 编译 R-3.6.0 时报错:
    checking for pcre/pcre.h... no
    checking if PCRE version >= 8.10, < 10.0 and has UTF-8 support... no
    checking whether PCRE support suffices... configure: error: pcre >= 8.10 library and headers are required
    # PCRE 安装需要 --enable-utf8，同时版本 >= 8.10 且 < 10.0

PCRE

在《R Installation and Administration: A.1 Essential programs and libraries》官方文档中要求, PCRE 版本最好在 8.32 及以上.

Either PCRE1 (version 8.32 or later, formerly known as just PCRE) or PCRE2 is required: PCRE2 is preferred and using PCRE1 requires configure option --with-pcre1. Only the 8-bit library and headers are needed if these are packaged separately. JIT support (optional) is desirable for the best performance. For PCRE2 >= 10.30 (which is desirable as matching has been re-written not to use recursion and the Unicode tables were updated to version 10).

# 源码安装 PCRE1
$ wget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz --no-check-certificate
$ tar zvxf pcre-8.40.tar.gz
$ cd pcre-8.40
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/pcre-8.40 --enable-utf8
$ make -j3 && make install

# root 安装 PCRE1
yum install pcre pcre-devel

# 源码的方式安装 PCRE2，这里不介绍，跟源码安装 PCRE1 原理是一样的，自己去谷歌就好
# root 安装 PCRE2
yum install pcre2 pcre2-devel

注意:

R-3.4.2 要求 pcre 版本(>= 8.20, < 10.0)；
R-4.0.1 要求 PCRE >= 8.32 with UTF-8 support；
configure: error: PCRE2 library and headers are required, or use --with-pcre1 and PCRE >= 8.32 with UTF-8 support。R-4.0 以上在 configure 时，需要增加一个 --with-pcre1 参数；或者安装 PCRE2！

重新安装 R-3.6.0:

$ cd ../R-3.6.0
$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0  --enable-R-shlib LDFLAGS="-L/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/lib -L/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/lib -L/Bioinfo/SoftWare/NewLibs/pcre-8.40/lib" CPPFLAGS="-I/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/include -I/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/include -I/Bioinfo/SoftWare/NewLibs/pcre-8.40/include"

    报错：
    checking curl/curl.h usability... yes
    checking curl/curl.h presence... yes
    checking for curl/curl.h... yes
    checking if libcurl is version 7 and >= 7.28.0... no
    configure: error: libcurl >= 7.28.0 library and headers are required with support for https
    # 需要安装 curl >= 7.28.0

curl or libcurl

在《R Installation and Administration: A.1 Essential programs and libraries》要求, libcurl 大于或等于 7.22.0 版本。Library libcurl (version 7.22.0 or later) is required, with at least 7.28.0 being desirable.

$ wget https://curl.haxx.se/download/curl-7.64.1.tar.gz --no-check-certificate
$ tar zvxf curl-7.64.1.tar.gz
$ cd curl-7.64.1

## 不指定证书
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/curl-7.64.1

## 指定证书(推荐)
$ wget https://curl.haxx.se/ca/cacert.pem -O /Bioinfo/SoftWare/certs/ca-bundle.crt --no-check-certificate
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/curl-7.64.1 --with-ca-bundle=/Bioinfo/SoftWare/certs/ca-bundle.crt 

$ make
$ make install

如果你有管理员的权限，你也可以使用 root 的方法直接安装 libcurl：

# CentOS 7.6 自带的 libcurl 最新版本应该是 7.29.0-59.el7_9.1
yum install libcurl libcurl-devel

注意:

有些情况下，R 在链接一些在线数据库，或者下载某些特殊包时，可能导致 SSL certificate problem: unable to get local issuer certificate 异常，这种情况可以通过 --with-ca-bundle 指定证书来解决。
参考下面的内容。

R 语言关于 SSL 证书异常处理笔记

重新安装 R-3.6.0:

$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0  --enable-R-shlib LDFLAGS="-L/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/lib -L/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/lib -L/Bioinfo/SoftWare/NewLibs/pcre-8.40/lib -L/Bioinfo/SoftWare/NewLibs/curl-7.64.1/lib" CPPFLAGS="-I/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/include -I/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/include -I/Bioinfo/SoftWare/NewLibs/pcre-8.40/include -I/Bioinfo/SoftWare/NewLibs/curl-7.64.1/include"

$ make 

    报错：
    /Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/lib/libbz2.a: could not read symbols: Bad value
    collect2: ld returned 1 exit status
    make[3]: *** [libR.so] Error 1
    make[3]: Leaving directory `/home/shenweiyan/inst/R-3.6.0/src/main'
    make[2]: *** [R] Error 2

    make[1]: Leaving directory `/home/shenweiyan/inst/R-3.6.0/src'
    make: *** [R] Error 1
    # 需要使用64位元的方法重新编译 bzip2

重装 bzip2-1.0.6, 如下所示, 首先修改 bzip2-1.0.6 的 Makefile 文件:

CC=gcc -fPIC
AR=ar
RANLIB=ranlib
LDFLAGS=

BIGFILES=-D_FILE_OFFSET_BITS=64

然后, 重新编译 bzip2-1.0.6:

$ make clean
$ make
$ make install PREFIX=/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6

liblzma

在编译过程中发现: "configure: error: "liblzma library and headers are required", 需要安装 xz, 对应主页: https://tukaani.org/xz/, 安装如下:

$ wget https://nchc.dl.sourceforge.net/project/lzmautils/xz-5.2.3.tar.gz
$ tar zvxf xz-5.2.3.tar.gz
$ cd xz-5.2.3/
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/xz-5.2.3
$ make -j3
$ make install

libtiff

R shell 中使用 capabilities() 可以查看 R 已经编译支持的功能, 对于画图可以增加下面几个参数, 使 R 支持对应格式的图片保存, 与此同时要确保对应库已经安装.

--with-cairo            use cairo (and pango) if available [yes]
--with-libpng           use libpng library (if available) [yes]
--with-jpeglib          use jpeglib library (if available) [yes]
--with-libtiff          use libtiff library (if available) [yes]

以 tiff 为例, 需要安装 libtiff 库:

The bitmapped graphics devices jpeg(), png() and tiff() need the appropriate headers and libraries installed: jpeg (version 6b or later, or libjpeg-turbo) or libpng (version 1.2.7 or later) and zlib or libtiff(versions 4.0.[5-10] have been tested) respectively.

$ wget ftp://download.osgeo.org/libtiff/tiff-4.0.9.zip
$ unzip tiff-4.0.9.zip
$ cd tiff-4.0.9
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/tiff-4.0.9
$ make
$ make install

如果你有管理员权限，你也可以直接使用 root 直接安装 libtiff：

# CentOS 7.6 自带的 libcurl 最新版本应该是 4.0.3-35.el7
yum install libtiff libtiff-devel

然后重新编译 R-3.6.0:

$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0 --enable-R-shlib --with-libtiff LDFLAGS="-L/Bioinfo/SoftWare/NewLibs/tiff-4.0.9/lib" CPPFLAGS="-I/Bioinfo/SoftWare/NewLibs/tiff-4.0.9/include"

如果 tiff 无法使用, 可以考虑在 ~/.bashrc 中添加 libtiff 库路径, 然后重新再编译 R .

export LD_LIBRARY_PATH=/Bioinfo/SoftWare/NewLibs/tiff-4.0.9/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/Bioinfo/SoftWare/NewLibs/tiff-4.0.9/lib/pkgconfig:$PKG_CONFIG_PATH

libjpeg and libpng16

R 安装完以后, 使用 plot 进行画图, 如果出现如下错误:

> plot(1:0)
Error in (function (display = "", width, height, pointsize, gamma, bg,  :
  X11 module cannot be loaded
In addition: Warning message:
In (function (display = "", width, height, pointsize, gamma, bg,  :
  unable to load shared object '/Bioinfo/SoftWare/R-3.6.0/lib64/R/modules//R_X11.so':
  libjpeg.so.9: cannot open shared object file: No such file or directory
> quit()
Save workspace image? [y/n/c]: n

使用 ldd 命令如果看到 libjpeg.so.9、libpng16.so.16 not found，则可以考虑手动安装这两个包：

$ /Bioinfo/SoftWare/R-3.6.0/bin/R CMD ldd /Bioinfo/SoftWare/R-3.6.0/lib64/R/modules//R_X11.so
        linux-vdso.so.1 =>  (0x00007fff3c79b000)
        libtiff.so.5 => /Bioinfo/SoftWare/NewLibs/tiff-4.0.9/lib/libtiff.so.5 (0x00007f75369dc000)
        libjpeg.so.9 => not found
        libpng16.so.16 => not found
        libpangocairo-1.0.so.0 => /usr/lib64/libpangocairo-1.0.so.0 (0x00007f75367ba000)
        libpango-1.0.so.0 => /usr/lib64/libpango-1.0.so.0 (0x00007f753656e000)
        libgobject-2.0.so.0 => /lib64/libgobject-2.0.so.0 (0x00007f7536322000)
        ......

libjpeg.so.9, libpng16.so.16 安装步骤如下:

$ wget http://www.ijg.org/files/jpegsrc.v9c.tar.gz
$ tar zvxf jpegsrc.v9c.tar.gz
$ cd jpeg-9c
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/jpeg-9c
$ make
$ make install

$ wget https://download.sourceforge.net/libpng/libpng-1.6.37.tar.gz
$ tar zvxf libpng-1.6.37.tar.gz
$ cd libpng-1.6.37
$ ./configure --prefix=/Bioinfo/SoftWare/NewLibs/libpng-1.6.37
$ make
$ make install

http://libjpeg.sourceforge.net/

4. 完整编译安装命令

如果使用了自定义安装的 gcc/c++ 进行编译, 需要在 configure 时候使用 CC/CXX 进行指定, 否则使用系统默认的 gcc/c++，由于 CentOS-6.5 默认的 gcc==4.4.7, 该版本的 gcc 会导致 R>=3.5.0 编译出现各种错误，非 root 用户手动升级 gcc 可以参考：
非 root 用户手动编译安装 GCC

最后，CentOS 下 R 源码安装的完整 configure 命令如下（同样适用于 Ubuntu/Debian）：

# 粘贴到命令行时，请把 \ 去掉，连成一行命令再回车执行
$ ./configure --prefix=/Bioinfo/SoftWare/R-3.6.0 \
  CC=/Bioinfo/SoftWare/gcc-4.8.5/bin/gcc \
  CXX=/Bioinfo/SoftWare/gcc-4.8.5/bin/c++ \
  --enable-R-shlib --with-libtiff --with-libpng --with-jpeglib \
  --with-x --with-cairo --with-pcre1\
  LDFLAGS="-L/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/lib \

  -L/Bioinfo/SoftWare/NewLibs/jpeg-9c/lib \
  -L/Bioinfo/SoftWare/NewLibs/libpng-1.6.37/lib" \ 
  CPPFLAGS="-I/Bioinfo/SoftWare/NewLibs/zlib-1.2.6/include \ 
  -I/Bioinfo/SoftWare/NewLibs/bzip2-1.0.6/include \ 
  -I/Bioinfo/SoftWare/NewLibs/pcre-8.40/include \
  -I/Bioinfo/SoftWare/NewLibs/curl-7.64.1/include \
  -I/Bioinfo/SoftWare/NewLibs/tiff-4.0.9/include \
  -I/Bioinfo/SoftWare/NewLibs/jpeg-9c/include \
  -I/Bioinfo/SoftWare/NewLibs/libpng-1.6.37/include"

# configure 的所有配置信息，都会保存在 ./Makeconf 文件中

注意：

--with-x，--with-cairo 是开启 X11 图形化的参数，应该增加一下。
R-4.0 以上需要增加一个 --with-pcre1 参数，或者直接使用 PCRE2。
最后关于 HTML 的 WARNING 不会影响 R 的安装和使用，可以忽略。

最后，使用 make 和 make install 完成安装。

$ make 
$ make install

5. 设置环境变量

最后, 把安装完成的 R 添加至环境变量:

export R_HOME=path-to-R
export R_LIBS=$R_HOME/lib64/R/library
export LD_LIBRARY_PATH=$R_HOME/lib:$LD_LIBRARY_PATH
export PATH=$R_HOME/bin:$PATH

R_LIBS 的作用是 python 的 rpy2 调用安装的 R 包时，根据该变量寻找对应的包；
LD_LIBRARY_PATH 则是相关动态依赖库需要查找的路径；
环境变量设置中比较容易漏掉的是 PATH 和 LD_LIBRARY_PATH，如果是用 root 安装，可能会没有问题，如果安装到个人目录下，不添加这两个变量的话，就无法正确寻找需要的动态链接库，如下：

$ python
Python 2.7.14 (default, Mar  9 2018, 08:39:17)
