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

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.

1 sudo apt-get install binutils gcc make m4 perl tar

1 sudo apt-get install dpkg-dev

• dvipng
• ffmpeg
• ImageMagick
• latex --十分建议安装

1 sudo apt-get install dvipng imagemagick texlive

1 cd ~/sage-6.7    #进入目录
2 export SAGE_FAT_BINATY=‘‘yes‘‘　
3 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

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

./sage --testall
