Cmake installation is failing

Question

I'm trying to install CMake in Linux (RHEL). When I run the bootstrap script it throws following error:

---------------------------------------------
CMake 3.5.2, Copyright 2000-2016 Kitware, Inc.
Found GNU toolchain
---------------------------------------------
Error when bootstrapping CMake:
Cannot find appropriate C compiler on this system.
Please specify one using environment variable CC.
See cmake_bootstrap.log for compilers attempted.
---------------------------------------------
Log of errors: /usr/cmake-3.5.2/Bootstrap.cmk/cmake_bootstrap.log


**Contents of the log file are as follows**

I have gcc and g++ installed in the directory /usr/bin/.

Can anyone help me resolve this issue please?

Read the error logs:

cmake_bootstrap_5875_test.c:6:18: error: stdio.h: No such file or directory

Looks like the header files for the C library are not (properly) installed. They should have been installed automatically along with GCC. Did you install GCC manually? Check whether package "glibc-devel" is installed.
