gcc is definitely available in the RHEL channels. However, whether or not it is installed would depend on the packages selected for the installation. Use yum to install gcc:

Raw

# yum install gcc

And if you would like to install development tools such as autoconf, automake, flex, c++ compiler, etc:

Raw

# yum grouplist

Available Groups:
   Backup Client

诊断步骤

How to verify your gcc installation:

Raw

$ whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz

How to see gcc compiler version:

Raw

$ gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)
Copyright (C) 2010 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

Let's create a little program to test if gcc is working:

Raw

$ vi redhat.c

Raw

#include<stdio.h>
int main(void){
    printf("Hello Red Hat!\n");
    return 0;
}

Now, let's compile to generate an executable file:

Raw

$ gcc redhat.c -o redhat

Execute the program:

Raw

$ ./redhat
Hello Red Hat!
