# glibc 版本低的解决方法 以及升级后遇到的问题解决
|
|
|
|
|
|
centos 升级gcc 环境
|
|
|
|
|
|
```shell
|
|
|
|
|
|
yum -y install centos-release-scl
|
|
|
|
|
|
yum -y install devtoolset-8-gcc devtoolset-8-gcc-c++ devtoolset-8-binutils
|
|
|
|
|
|
scl enable devtoolset-8 bash
|
|
|
|
|
|
echo "source /opt/rh/devtoolset-8/enable" >>/etc/profile
|
|
|
|
|
|
yum install -y bison
|
|
|
|
|
|
```
|
|
|
|
|
|
升级make
|
|
|
|
|
|
```shell
|
|
|
|
|
|
wget http://ftp.gnu.org/gnu/make/make-4.2.tar.gz
|
|
|
|
|
|
tar -xzvf make-4.2.tar.gz
|
|
|
|
|
|
cd make-4.2
|
|
|
|
|
|
sudo ./configure
|
|
|
|
|
|
sudo make
|
|
|
|
|
|
sudo make install
|
|
|
|
|
|
sudo rm -rf /usr/bin/make
|
|
|
|
|
|
sudo cp ./make /usr/bin/
|
|
|
|
|
|
make -v
|
|
|
|
|
|
```
|
|
|
|
|
|
升级glibc
|
|
|
|
|
|
```shell
|
|
|
|
|
|
cd /wanghao/glibc
|
|
|
|
|
|
wget https://mirror.bjtu.edu.cn/gnu/libc/glibc-2.28.tar.xz --no-check-certificate
|
|
|
|
|
|
tar -xf glibc-2.28.tar.xz
|
|
|
|
|
|
cd glibc-2.28/
|
|
|
|
|
|
mkdir build
|
|
|
|
|
|
cd build
|
|
|
|
|
|
sudo ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
|
|
|
|
|
|
make -j 8 #make 运行时间较长 开启多线程任务编译 开启数量 8
|
|
|
|
|
|
make install
|
|
|
|
|
|
```
|
|
|
|
|
|
查看环境中所有GLIBC
|
|
|
|
|
|
```shell
|
|
|
|
|
|
ls -la /lib64/libc.so.6
|
|
|
|
|
|
strings /lib64/libc.so.6 |grep GLIBC
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 问题解决
|
|
|
|

|
### 升级libc后导致中文乱码
|
|
|
|
|
|
如果编译目录没有删除 ，则进入glibc的编译目录，也就是build目录
|
|
|
|
|
|
```
|
|
|
|
|
|
make localedata/install-locales
|
|
|
|
|
|
```
|
|
|
|
|
|
再次执行 locale 这时应该已经正常了
|
|
|
|
|
|
但是如果你已经删除了编译glibc的build目录或者不知道build的目录在哪里
|
|
|
|
|
|
查看 locale-archive 归档文件目录
|
|
|
|
|
|
```
|
|
|
|
|
|
strings /lib64/libc-2.28.so | grep locale-archive
|
|
|
|
|
|
```
|
|
|
|
|
|
查看```目标``` 结果中有没有 locale-archive
|
|
|
|
|
|
|
|
|
|
|
|
没有就将/usr/lib/locale/locale-archive 软连接到目标位置
|
|
|
|
|
|
```
|
|
|
|
|
|
ln -s /usr/lib/locale/locale-archive 目标
|
|
|
|
|
|
```
|
