How do I configure GCC, g++, and gdb in CentOS?

The use of GCC in Linux to compile C programs, using g++ to compile C + + programs, using GDB to debug the program, these tools need to install themselves, then how should you configure these tools?

First, enter VI on the command line to view the VIM information as follows:

Then, enter ls-a to see if there is a configuration file such as. VIMRC and. Viminfo, and the results are as follows:

1. Configure GCC, g++

Using Yum in CentOS to configure GCC and g++, to install GCC, enter on the command line: yum-y install GCC, press ENTER to enable GCC installation, to install g++, you need to enter on the command line: yum-y install gcc-c++ , it is possible to install the g++.

2. Configure GDB

Here are the specific steps to configure GDB:

(1) In the Linux system, open the Web page http://ftp.gnu.org/gnu/gdb/, the following interface will appear:

Here are some of the GDB tool's compressed packages, and then we select one of the versions to download, and here I choose the gdb-7.10 version. After downloading, use the LS command to view the downloaded file as follows:

(2) After downloading, the compressed file must be decompressed, in the command Window input: Tar xzvf gdb-7.10.tar.gz, after extracting, can see a file gdb-7.10:

(3) Enter the extracted directory: CD gdb-7.10

(4) Enter command:./configure, use Dir to view after completion

(5) Input command: make, compile gdb

(6) Then use: Make install, install GDB

(7) Use: Gdb-v view GDB version information to confirm the installation is correct

The above is the configuration of GCC, g++, GDB, the main process, if strictly according to the above steps, generally will not have problems, GDB installation process a little bit of trouble, I hope the reader can be patient.
