Ubuntu 14.04 LTS 下使用源码编译安装 Sagemath 6.7 x64 (小结)

1. 下载源码包
2. 系统的最低要求：　６ＧＢ　硬盘　；　２ＧＢ　ＲＡＭ．
3. 命令行工具：
   1. A C/C++ compiler: Since Sage builds its own GCC if needed, a wide variety of C/C++ compilers is supported.
      Many GCC versions work, from as old as version 3.4.3 to the most recent release. Clang also works. On Solaris
      systems, the Sun compiler should also work. See also Using alternative compilers.
   2. make: GNU make, version 3.80 or later. Version 3.82 or later is recommended.
   3. m4: GNU m4 1.4.2 or later (non-GNU or older versions might also work).
   4. perl: version 5.8.0 or later.
   5. ar and ranlib: can be obtained as part of GNU binutils.
   6. tar: GNU tar version 1.17 or later, or BSD tar.
4. 命令行工具安装

   sudo apt-get install binutils gcc make m4 perl tar

5. 系统特殊需求，Debian/Ubuntu需要安装dpkg-dev包

   sudo apt-get install dpkg-dev

6. 可选软件
   • dvipng
   • ffmpeg
   • ImageMagick
   • latex --十分建议安装
7. 安装可选软件．

   sudo apt-get install dvipng imagemagick texlive

8. 安装ffmpeg

   sudo add-apt-repository ppa:samrog131/ppa
   sudo apt-get update
   sudo apt-get install ffmpeg-real
   sudo ln -sf /opt/ffmpeg/bin/ffmpeg /usr/bin/ffmpeg

9. 开始编译

   cd ~/sage-6.7    #进入目录
   export SAGE_FAT_BINATY=''yes''　
   MAKE='make -j4' make　＃不可以使用ｒｏｏｔ

   Warning::系统默认的GCC-4.9.2.p1在会出现问题后，Ｓａｇｅ默认使用自带的ＧＣＣ，由于版本问题导致Ｒ安装不上，出现如下ＥＲＲＯＲ

   /home/user/build/sage/snapperkob/sage_git/build/local/var/tmp/sage/build/r-3.1.1.p0/src/bin/exec/R: /usr/lib/x86_64-linux-gnu/libgomp.so.1: version `GOMP_4.0' not found (required by /home/user/build/sage/snapperkob/sage_git/build/local/var/tmp/sage/build/r-3.1.1.p0/src/lib/libR.so)
   make[7]: *** Error sysdate
   make[6]: *** [all] Error 1
   make[6]: Leaving directory `/home/user/build/sage/snapperkob/sage_git/build/local/var/tmp/sage/build/r-3.1.1.p0/src/src/library/tools'
   make[5]: *** [R] Error 1

   make[4]: Leaving directory `/home/user/build/sage/snapperkob/sage_git/build/local/var/tmp/sage/build/r-3.1.1.p0/src/src'

   make[3]: Leaving directory `/home/user/build/sage/snapperkob/sage_git/build/local/var/tmp/sage/build/r-3.1.1.p0/src'
   Error building R.

   设置第二步可以避免出现错误　SAGE_FAT_BINARY参数的作用：

   to prepare a binary distribution that will run on the widest range of target machines.

   ./sage --bdisk x.y.z-fat  #生成 .tar.gz　包文件

10. 测试

    ./sage --testall

11. 安装可选包
    1. sage -i <package name> 自动下载安装可选包,注意包名含有版本号
    2. Sage Optional Packages 
12. 命令行启动方式
    1. ln -s /path/to/sage-x.y.z/sage /usr/local/bin/sage
    2. 拷贝$SAGE_ROOT/sage至PATH（通常至/usr/local/bin）.编辑拷贝中#SAGE_ROOT=/path/to/sage-version.
13. 时间统计(Intel Core i5 3230m+8GB RAM +Ubuntu 14.04.02 amd64)

    项目	make	./sage --testall
    耗时	约2.5h	约1.2h
