下载源码

可选最新的，接下来执行以下命令：

tar -zxvf gdb-10.2.tar.gzcd gdb-10.2/mkdir buildcd build../configure --with-python=/usr/bin/python3.5 --enable-targets=allmake && make install

make 过程会有点长，一般会出现下面的错误：

WARNING: 'makeinfo' is missing on your system.         You should only need it if you modified a '.texi' file, or         any other file indirectly affecting the aspect of the manual.         You might want to install the Texinfo package:         
            The spurious makeinfo call might also be the consequence of         using a buggy 'make' (AIX, DU, IRIX), in which case you might         want to install GNU make:         
   make[5]: *** [gdb.info] Error 127make[5]: Leaving directory `/root/gcc-6.2.0/contrib/gdb-7.12/gdb/doc'make[4]: *** [subdir_do] Error 1make[4]: Leaving directory `/root/gcc-6.2.0/contrib/gdb-7.12/gdb'make[3]: *** [install-only] Error 2make[3]: Leaving directory `/root/gcc-6.2.0/contrib/gdb-7.12/gdb'make[2]: *** [install] Error 2make[2]: Leaving directory `/root/gcc-6.2.0/contrib/gdb-7.12/gdb'make[1]: *** [install-gdb] Error 2make[1]: Leaving directory `/root/gcc-6.2.0/contrib/gdb-7.12'make: *** [install] Error 2

提示安装Texinfo。

ubuntu直接apt install texinfo

centos直接yum install texinfo

然后接着make && make install 一般就没什么问题了。

接下来就是替换老版本，新生成的gdb二进制文件会在编译目录gdb-10.2/gdb/gdb ，将其拷贝到/usr/bin/，替换原来的，也可以将原来的做个备份，以防出问题，以下命令：

mv /usr/local/bin/gdb /usr/local/bin/gdb_bakcp ~/gdb-10.2/gdb/gdb /usr/local/bin/

查看gdb版本gdb -v

➜ ~/gdb-10.2/gdb$ gdb -v     GNU gdb (GDB) 10.2Copyright (C) 2021 Free Software Foundation, Inc.License GPLv3+: GNU GPL version 3 or later

完成。
