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  CMAKE C COMPILER ENV VAR CMake Error  Error required internal CMake variable not set  cmake may be not be built correctly  Missing variable is  CMAKE C COMPILER CMake Error  Could not find cmake module file C  Users Desk Dropbox 2012-2013 BCB504 AvidaProject avidagit avida CMakeFiles 2 8 10 2 CMakeCCompiler cmake CMake Error  Error required internal CMake variable not set  cmake may be not be built correctly  Missing variable is  CMAKE CXX COMPILER ENV VAR CMake Error  Error required internal CMake variable not set  cmake may be not be built correctly  Missing variable is  CMAKE CXX COMPILER CMake Error  Could not find cmake module file C  Users Desk Dropbox 2012-2013 BCB504 AvidaProject avidagit avida CMakeFiles 2 8 10 2 CMakeCXXCompiler cmake CMake Error  CMAKE C COMPILER not set  after EnableLanguage CMake Error  CMAKE CXX COMPILER not set  after EnableLanguage -- Configuring incomplete  errors occurred  make      No rule to make target  install    Stop

Those errors     CMake Error  CMAKE C COMPILER not set  after EnableLanguage  CMake Error  CMAKE CXX COMPILER not set  after EnableLanguage   means you haven t installed mingw32-base   Go to http   sourceforge net projects mingw files latest download source files  and then make sure you select  mingw32-base    Make sure you set up environment variables correctly in PATH section   C  MinGW bin    After that open CMake and Select Installation --  Delete Cache    And click configure button again  I solved the problem this way  hope you solve the problem

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     remove  CMakeCache txt   run compilation again

Even though I had gcc already installed  I had to run sudo apt-get install build-essential  to get rid of that error

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
