How to install Cmake C compiler and CXX compiler

Question

I need some help compiling this project with cmake. Here is the error message.

$ ./build_avida
-- Building for: NMake Makefiles
CMake Warning at CMakeLists.txt:1 (PROJECT):
  To use the NMake generator, cmake must be run from a shell that can use the
  compiler cl from the command line.  This environment does not contain
  INCLUDE, LIB, or LIBPATH, and these must be set for the cl compiler to
  work.


CMake Error: CMake was unable to find a build program corresponding to "NMake Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:

Answer 1

Try to install gcc and gcc-c++, as Cmake works smooth with them.

RedHat-based

yum install gcc gcc-c++

Debian/Ubuntu-based

apt-get install cmake gcc g++

Then,

1. remove 'CMakeCache.txt'
2. run compilation again.

Answer 2

Even though I had gcc already installed, I had to run

sudo apt-get install build-essential

to get rid of that error

Answer 3

The approach I use is to start the "Visual Studio Command Prompt" which can be found in the Start menu. E.g. my visual studio 2010 Express install has a shortcute Visual Studio Command Prompt (2010) at Start Menu\Programs\Microsoft Visual Studio 2010\Visual Studio Tools.

This shortcut prepares an environment by calling a script vcvarsall.bat where the compiler, linker, etc. are setup from the right Visual Studio installation.

Alternatively, if you already have a prompt open, you can prepare the environment by calling a similar script:

:: For x86 (using the VS100COMNTOOLS env-var)
call "%VS100COMNTOOLS%"\..\..\VC\bin\vcvars32.bat

or

:: For amd64 (using the full path)
call C:\Program Files\Microsoft Visual Studio 10.0\VC\bin\amd64\vcvars64.bat

However:

Your output (with the '$' prompt) suggests that you are attempting to run CMake from a MSys shell. In that case it might be better to run CMake for MSys or MinGW, by explicitly specifying a makefile generator:

cmake -G"MSYS Makefiles"
cmake -G"MinGW Makefiles"

Run cmake --help to get a list of all possible generators.
