安装gcc-11.1.0

gcc安装包：https://ftp.gnu.org/gnu/gcc/ g++安装包：https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/

configure（gcc）时缺少GMP库

checking for objdir... .libs

configure: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
https://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

安装GMP

https://gmplib.org/ 一切正常。

GMP是开源免费的高精度数学计算库（GNU Multiple Mrecision arithmetic library），它针对各种型号的CPU编写汇编代码、使用复杂算法实现高效率的高精度计算。GMP原生提供C接口，同时也封装了一层C++接口。

使用GMP之前，必须读一读文档的第三章3 GMP Basics。自己安装GMP，阅读2 Installing GMP。如下我做的笔记。

按官网手册，GMP直接发行的源码，没有预编译安装包。GMP源码原生使用Linux/Unix的autoconfig工具完成编译、安装；不支持CMake。从源码编译安装，Linux平台很方便，Windows平台上可以在Cygwin、DJGPP、MinGW中三种工具中任选一种。而实际上不少Linux发行版在他们的仓库中提供了预编译安装包：Ubuntu和CentOS可以直接使用apt和yum命令安装；Windows平台可以先安装MSYS，然后pacman -S mingw-w64-x86_64-gmp直接安装。

#include <gmpxx.h>
#include <iostream>
#include <stdio.h>
using namespace std;
int main()
{
        mpz_t a,b,c;
        mpz_init(a);
        mpz_init(b);
        mpz_init(c);
        gmp_scanf("%Zd%Zd",a,b);
        mpz_add(c,a,b);
        gmp_printf("c= %Zd\n",c);
        return 0;
}

安装MPFR

https://www.mpfr.org/mpfr-current/ 一切正常。

configure（gcc）时缺少MPC库

提示过MPFR版本过低，由于找的网上教程，给了一个当时的最新版本，下载最新版本成功。

./configure --disable-multilib搞定

安装gcc-11.1.0

不能直接make install，需要先make。然后就GG了。

准备放弃了，可能是版本跨度太大导致的吧，安装一个低版本的吧。

安装gcc-5.4.0

同样是安装失败。。。。。

/media/hankin/vdb/test/gcc-11.1.0/host-x86_64-pc-linux-gnu/gcc/cc1: error while loading shared libraries: libisl.so.23: cannot open shared object file: No such file or directory

发现这样根本没用： ./configure --enable-languages=c,c++ --enable-multilib --enable-obsolete --disable-threads --without-headers --disable-multilib --disable-decimal-float --disable-libgomp --disable-libmudflap --disable-nls --disable-shared --disable-libssp --with-newlib --with-isl=/usr/local/lib

找到文件libisl.so.23在/usr/local/lib目录下，添加： export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

brary.dep -c ../.././libgcc/../libdecnumber/decLibrary.c

发现../.././libgcc/../libdecnumber/目录下确实没有，百度decimal128.h文件也找不到，然后在bing下找到了decimal128.h文件原来在这个目录的dpd文件夹下面，修改头文件引入位置。

结论

我选择放弃，实在找不到怎么解决。应该是版本跨度太大，依赖太多。男上加男。还是使用apt install方便吧。
