# configure-windows.ps1
# =====================
#
# This script configures a qpid\cpp developer build environment under Windows
# to enable working with cpp\bindings\qpid\dotnet binding source code.
#
# * Supports multiple versions of Visual Studio (VS2008, VS2010) as CMake
#   generator.
#
# * Supports 32-bit and/or 64-bit development platforms.
#
# * User chooses in-source or out-of-source build directories.
#
#     - 'In-source' builds happen when CMake is run from directory qpid\cpp.
#       Hundreds of CMake-generated output files are placed in qpid\cpp\src.
#       These files go right on top of files that are part of the source tree
#       in qpid\cpp\src.
#       In-source builds support only one platform.
#       Choose only a 32-bit or a 64-bit platform but not both.
#
#     - Out-of-source builds happen when the user chooses another directory
#       under qpid in which to run CMake. Out-of-source builds are required
#       in order to build both x86 and x64 targets using the same source tree.
#       For each build platform (32-bit x86 or Win32, or 64-bit x64) the user
#       specifies a build directory and a specific version of Boost.
#       Many platform/Boost-version directories may reside side by side.
#
# * User chooses to run CMake or not.
#
#     - When a new build directory is created then the user is given the
#       option of running CMake in that directory. Running CMake is a
#       necessary step as CMake creates important source, solution, and
#       project files.
#
#     - If a directory "looks like" is has already had CMake run in it
#       then this script skips running CMake again.
#
#
# Prerequisites
#
#  1. Powershell must be installed.
#  2. 32-bit and/or 64-bit Boost libraries must be installed in separate
#     directories. A user system may have any number of Boost library
#     versions installed on it as long as each may be referred to through
#     a separate BOOST_ROOT directory path.
#  3. CMake 2.8 (or later) must be installed. The cmake\bin directory
#     must be in the user's path.
#  4. Boost library specifications may or may not be in the user's path.
#     The script author recommeds not to have Boost in the path and only
#     allow the Boost path to be specified by generated command procedures.
#  5. Visual Studio build environment must be installed.
#
#
# Use case: Create a new build environment
# ========================================
#
#  Required Boost:
#        32-bit library - C:\Boost
#        64-bit library - D:\Boost_64
#
#  Required Qpid checkout tree
#        C:\svn\qpid\...
#
#  Run this script. It will ask for four directories:
#
#        Needed info        User clicks on or adds new
#        ----------------   --------------------------
#        32-bit Boost       C:\boost
#        32-bit build dir   C:\svn\qpid\build32
#        64-bit Boost       D:\Boost_64
#        64-bit build dir   C:\svn\qpid\build64
#
#  In this example the build dirs are new. The script will prompt
#  asking if CMake is to run in the build directories. User chooses Yes.
#
#  Now this script runs CMake twice, once each with the 32-bit and 64-bit
#  generators.
#  * This step creates qpid-cpp.sln and related project files.
#      C:\svn\qpid\build32\qpid-cpp.sln
#      C:\svn\qpid\build64\qpid-cpp.sln
#
#  This script generates other scripts as follows:
#
#   C:\svn\qpid\build32\start-devenv-messaging-x86-32bit.ps1
#   C:\svn\qpid\build32\start-devenv-messaging-x86-32bit.bat
#   C:\svn\qpid\build32\setenv-messaging-x86-32bit.bat
#
#   C:\svn\qpid\build64\start-devenv-messaging-x64-64bit.ps1
#   C:\svn\qpid\build64\start-devenv-messaging-x64-64bit.bat
#   C:\svn\qpid\build64\setenv-messaging-x64-64bit.bat
#
#  Next the user compiles solution qpid\build32\qpid-cpp.sln.
#
# Using the generated scripts:
#
# Case 1. Run an executable in 32-bit mode.
#  1. Open a command prompt.
#  2. > CD   c:\svn\qpid\build32
#  3. > CALL setenv-messaging-x86-32bit.bat
#  4. > CD   src\debug
#  5. > run the chosen program
#
#  Note: Step #3 adds Boost to the user's path. This script selects the
#        version of Boost to match the executables in src\debug.
#
# Case 2. Launch Visual Studio org.apache.qpid.messaging.sln in 64-bit mode.
#  1. > CD c:\svn\qpid\build64
#  2. > powershell start-devenv-messaging-x64-64bit.ps1
#     or
#  1. Double-click c:\svn\qpid\build64\start-devenv-messaging-x64-64bit.bat
#
#  Note: In this case the scripts set QPID_BUILD_ROOT to point to the out-of-
#        source directory used by qpid-cpp.sln. Also the scripts put Boost in
#        the path so that executables may run directly from Visual Studio.
