Installing dealii-8.2.1 in Linux Mint 17.1


I am trying to install dealii-8.2.1 software in Linux Mint using the Virtual Box in a 32-bit windows desktop. But I am getting the error message regarding the CMAKE_CXX_COMPILER. How to get rid of it? Please follow the error message that appears during installation through terminal window.

Code:
-- This is CMake 2.8.12.2 
CMake Error at CMakeLists.txt:61 (INCLUDE): 
  include could not find load file: 

    setup_external_macros 


CMake Error at CMakeLists.txt:86 (INCLUDE): 
  include could not find load file: 

    setup_cached_variables 


-- The CXX compiler identification is unknown 
-- The C compiler identification is GNU 4.8.2 
-- Check for working C compiler: /usr/bin/cc 
-- Check for working C compiler: /usr/bin/cc -- works 
-- Detecting C compiler ABI info

CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name. 
CMake Error at CMakeLists.txt:92 (ENABLE_LANGUAGE_OPTIONAL):

You aren't, by any chance, trying to compile this lib outside of the build directory, are you? If you try to "make" outside the build directory "make install <switches/options> /path/to/build_directory" you anger the compiler gods, and they are a venal bunch.

The reason I'm asking is the only time I can remember seeing this error...

I was engaged in such foolishness.

BTW, did you look in " /home/hasib/Downloads/dealii-8.2.1/build/CMakeFiles/CMakeError.log" to see what make was whining about when it died?

"deal.II" : Latest is https://github.com/dealii/dealii
There may be some updates for version `~8.2.1' ...
$ git clone https://github.com/dealii/dealii


Your issues : Seems to be an incomplete install of "gcc-4.8".
Please do : $ sudo apt-get install g++
