linux离线安装软件（三）——gcc手动安装依赖包

Centos7源码安装gcc（二）——手动安装依赖包

以gcc-5.5.0编译安装为例：

参考链接：https://www.cnblogs.com/chillax1314/articles/11095950.html

1、前置条件

已安装低版本gcc，gcc-g++

 

2、编译安装

tar -zxf gcc-5.5.0.tar.gz

mkdir /usr/local/gcc-5.5.0/

gcc-5.5.0/configure --prefix=/usr/local/gcc-5.5.0

如果出现如下错误，说明缺少依赖库GMP、MPFR、MPC

1）安装GMP4.3.2

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2

tar jxvf gmp-4.3.2.tar.bz2

mkdir /usr/local/gmp-4.3.2

gmp-4.3.2/configure -prefix=/usr/local/gmp-4.3.2

make -j 32

make install

 

2）安装MPFR2.4.2

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2

tar -jxvf mpfr-2.4.2.tar.bz2

mkdir /usr/local/mpfr-2.4.2

cd /usr/local/mpfr-2.4.2

mpfr-2.4.2/configure --prefix=/usr/local/mpfr-2.4.2 --with-gmp=/usr/local/gmp-4.3.2

make -j 32

make install

 

3）安装MPC0.8.1

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz

tar -zxf mpc-0.8.1.tar.gz

mkdir /usr/local/mpc-0.8.1


mpc-0.8.1/configure --prefix=/usr/local/mpc-0.8.1 --with-gmp=/usr/local/gmp-4.3.2 --with-mpfr=/usr/local/mpfr-2.4.2
make -j 32

make install

 

4）添加环境变量

# vim /etc/profile.d/software.sh，添加以下内容：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib

source /etc/profile.d/software.sh

 

5）再次配置GCC

/opt/gcc-5.3.0/configure --prefix=/usr/local/gcc-5.5.0 -enable-threads=posix -disable-checking -disable-multilib -enable-languages=c,c++ --with-gmp=/usr/local/gmp-4.3.2 --with-mpfr=/usr/local/mpfr-2.4.2 --with-mpc=/usr/local/mpc-0.8.1

 

6）编译

make -j 32

 

7）安装

make install

 

8）制作软链接

请确保PATH中 /usr/local/bin 在原gcc路径之前

ln -s /usr/local/gcc-5.5.0/bin/gcc /usr/local/bin/gcc 
ln -s /usr/local/gcc-5.5.0/bin/g++ /usr/local/bin/g++

 

9）添加环境变量

# vim /etc/profile.d/software.sh

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/gcc-5.5.0/lib:/usr/local/gcc-5.5.0/lib64

 

3、问题解决

1）在make 时报错：configure: error: cannot compute suffix of object files: cannot compile

• vim /etc/profile.d/software.sh，添加以下内容：

  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/mpc-0.8.1/lib:/usr/local/gmp-4.3.2/lib:/usr/local/mpfr-2.4.2/lib
  

• source /etc/profile.d/software.sh

 

2）编译GCC 报错：configure: error: error verifying int64_t uses long long

没有安装g++所致，可在线安装 yum install -y gcc-g++，或离线安装rpm包 yum --downloadonly --downloaddir=./ install -y gcc-c++

 

3）在configure报错：error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons)
说明没有安装m4，使用 yum install m4，然后再执行即可
