"Linus" configuration gcc, g++, and GDB

Using GCC from Linux to compile C programs, using g++ to compile C + + programs, using GDB to debug programs, which need to be installed on their own, how should you configure these tools?

1. View the VIM information and see if there are any. vimrc and. Viminfo Profiles

2. Configure GCC, g++

Use Yum in CentOS to configure GCC and g++.

To install GCC, on the command line enter: yum-y install GCC, press ENTER to be able to perform GCC installation, to install g++, you need to enter on the command line: yum-y install gcc++, you can do g++ installation.

Note: The following may occur if you enter the above instructions

Therefore, you need to root, enter Su, and then enter the password. Enter the password, the password is not visible, and then enter the above instructions can be used for GCC and g++ installation, as shown, appears complete! Indicates that the installation was successful.

But found in the installation of g++, prompted that there is no relevant g++ package. That's a different order. Yum Install gcc-c++ then enter y to download the g++ installation package, or enter the Yum install gcc-c++ directly. (The virtual machine must have a network, the specific settings can be found online)

3. Configuring 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, here I choose the gdb-7.11 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-7.11.tar.gz, after extracting, can see a file gdb-7.11:

(3) Enter the extracted directory: CD gdb-7.10, enter command:./configure, use Dir to view after completion

(4) Input command: make, compile gdb

(5) Then use: Make install, install GDB

(6) Use: gdb-v, view GDB version information to confirm the installation is correct
