centos 安装gmpy2

先安装3个依赖gmp,mpfr,mpc

    1、安装gmp  

        wget https://gmplib.org/download/gmp/gmp-6.1.2.tar.xz
        tar xvf gmp-6.1.2.tar.xz
        cd gmp-6.1.2
        ./configure –prefix=/usr/local/gmp
        make && make install

    2、安装mpfr 

        wget https://www.mpfr.org/mpfr-current/mpfr-4.1.0.tar.gz

        tar -zxvf mpfr-4.1.0.tar.gz

        cd mpfr-4.1.0

        在mpfr 的src下的mpfr.h该行代码下面添加代码

                #define mpfr_add_one_ulp(x,r)
                (mpfr_sgn (x) > 0 ? mpfr_nextabove (x) : mpfr_nextbelow (x))
                #define mpfr_sub_one_ulp(x,r)
                (mpfr_sgn (x) > 0 ? mpfr_nextbelow (x) : mpfr_nextabove (x))

    然后执行

        ./configure --prefix=/usr/local/mpfr --with-gmp=/usr/local/gmp

        make  && make install

    3、安装mpc

        wget ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.3.tar.gz
        tar xvf mpc-1.0.3.tar.gz
        cd mpc-1.0.3

        修改：

                将mul.c内的所有mpfr_fmma函数改名为mpfr_fmma_mul

        ./configure –prefix=/usr/local/mpc –with-gmp=/usr/local/gmp -with-mpfr=/usr/local/mpfr
        make && make install

安装gmpy2 

wget https://github.com/aleaxit/gmpy/releases/download/gmpy2-2.1.0a1/gmpy2-2.1.0a1.tar.gz
tar xf gmpy2-2.1.0a1.tar.gz && cd gmpy2-2.1.0a1
python3 setup.py build_ext --static=$HOME/static install

验证：

命令行进入python模式后，输入import gmpy2没报错就成功了。
