tips：
如果不能科學上網，那么ftp是訪問不了的，可以直接把ftp三個字母換成http，親測有效。
安裝
#su #cd /opt #wget http://ftp.gnu.org/gnu/gcc/gcc-5.3.0/gcc-5.3.0.tar.gz
安裝前置
你的編譯器告訴你還需要GMP啊，等等，就是說你需要前置的三個安裝包。
然后按照：
https://www.cnblogs.com/damonxu/p/6434265.html
的方法把ftp統統改成http進行安裝。
每安裝完一個都要用
make check
看下安裝情況
5.4降到5.3的安裝
../gcc-5.3.0/configure --enable-checking=release --enable-languages=c,c++ --disable-multilib --with-gmp=/usr/local/gmp-4.3.2 --with-mpfr=/usr/local/mpfr-2.4.2 --with-mpc=/usr/local/mpc-0.8.1
這個前面的..請換成你的gcc解壓包的路徑，絕對的或者相對的都可以。
錯誤錦集：
就是之前說的，make check。安裝gmp時，作者提示強烈建議運行sudo make check
- 檢查下有沒有錯誤。然后我就出現了如下錯誤。這句命令以上博客都沒有提到。
1 of 58 tests failed Please report to gmp-bugs@gmplib.org ==================================== Makefile:1004: recipe for target 'check-TESTS' failed make[4]: *** [check-TESTS] Error 1 make[4]: Leaving directory '/usr/local/gmp-4.3.2/tests/mpz' Makefile:1104: recipe for target 'check-am' failed make[3]: *** [check-am] Error 2 make[3]: Leaving directory '/usr/local/gmp-4.3.2/tests/mpz' Makefile:505: recipe for target 'check-recursive' failed make[2]: *** [check-recursive] Error 1 make[2]: Leaving directory '/usr/local/gmp-4.3.2/tests' Makefile:925: recipe for target 'check-recursive' failed make[1]: *** [check-recursive] Error 1 make[1]: Leaving directory '/usr/local/gmp-4.3.2' Makefile:1183: recipe for target 'check' failed make: *** [check] Error 2
相關錯誤只有這里：
https://gmplib.org/list-archives/gmp-bugs/2013-November/003225.html
找到了,鑒於還是安裝上了，所以暫時不管。
- 之后全部走完該安裝gcc了，在make 的時候出現了如下錯誤：

然后我檢查了日志

對於安裝到一半錯了，我的辦法是直接刪除安裝文件夾，然后看看差什么，重新開始
- 首先，整了下路徑：
export LD_LIBRARY_PATH=/opt/gmp-5.0.1/lib:/opt/mpfr-3.1.4/lib/:/opt/mpc-1.0:$LD_LIBRARY_PATH
- 然后看了下
/usr/local/gcc-5.3/missing: 81: /usr/local/gcc-5.3/missing: makeinfo: not found checking for expect... no
解決方法來自：https://stackoverflow.com/questions/338317/what-is-makeinfo-and-how-do-i-get-it
之后再次生成makefile
sudo apt-get install texinfo
sudo /usr/local/gcc-5.3/configure --prefix=/usr/local/gcc-5.3/objdir --enable-languages=c,c++ --enable-threads=posix --disable-multilib --disable-nls --disable-bootstrap --with-gmp=/usr/local/gcc-5.3/gmp-4.3.2 --with-mpfr=/usr/local/gcc-5.3/mpfr-2.4.2 --with-mpc=/usr/local/gcc-5.3/mpc-0.8.1
然后就沒了
- 再次運行
-
sudo make
再次出現了這個問題
-

Round 2
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/gcc-5.3/mpc-0.8.1/lib:/usr/local/gcc-5.3/gmp-4.3.2/lib:/usr/local/gcc-5.3/mpfr-2.4.2/lib/
我再次更改了我路徑的說法，一般情況下，找不到東西，都是應為路徑問題。

還是出現了那個問題
我決定鴿了。應該是版本問題，以前的版本比較頑固
