In this issue, the editor will bring you the operation method of upgrading redhat 6.8 default gdb 7.2 to gdb 8.3.1. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Recently, using gdb to debug and analyze the mysql 8.0.18 source code, it is found that the gdb version is too low to effectively track the mysql 8.0.18 source code. In addition, in order to compile and install the mysql 8.0.18 source code, the default gcc version was upgraded to gcc 8.3.1. Thus it can be seen that there is a compatible dependency between gcc and gdb versions.

Textinfo-6.6.tar.gz is installed
