:: Multi-Platform Build Tool for MSVC
::

REM
REM This batch script is used to build the SQLite DLL for multiple platforms
REM and configurations using MSVC.  The built SQLite DLLs, their associated
REM import libraries, and optionally their symbols files, are placed within
REM the directory specified on the command line, in sub-directories named for
REM their respective platforms and configurations.  This batch script must be
REM run from inside a Visual Studio Command Prompt for the desired version of
REM Visual Studio ^(the initial platform configured for the command prompt does
REM not really matter^).  Exactly one command line argument is required, the
REM name of an existing directory to be used as the final destination directory
REM for the generated output files, which will be placed in sub-directories
REM created therein.  Ideally, the directory specified should be empty.
REM
REM Example:
REM
REM                        CD /D C:\dev\sqlite\core
REM                        CALL tool\build-all-msvc.bat C:\Temp
REM
REM In the example above, "C:\dev\sqlite\core" represents the root of the
REM source tree for SQLite and "C:\Temp" represents the final destination
REM directory for the generated output files.
REM
REM Please note that the SQLite build process performed by the Makefile
REM associated with this batch script requires a Tcl shell to be present
REM in a directory contained in the PATH environment variable unless a
REM pre-existing amalgamation file is used.
REM
REM There are several environment variables that may be set to modify the
REM behavior of this batch script and its associated Makefile.  The list of
REM platforms to build may be overriden by using the PLATFORMS environment
REM variable, which should contain a list of platforms ^(e.g. x86 x86_amd64
REM x86_arm^).  All platforms must be supported by the version of Visual Studio
REM being used.  The list of configurations to build may be overridden by
REM setting the CONFIGURATIONS environment variable, which should contain a
REM list of configurations to build ^(e.g. Debug Retail^).  Neither of these
REM variable values may contain any double quotes, surrounding or embedded.
REM
REM Finally, the NCRTLIBPATH, NUCRTLIBPATH, and NSDKLIBPATH environment
REM variables may be set to specify the location of the CRT, Universal CRT, and
REM Windows SDK, respectively, that may be needed to compile executables native
REM to the architecture of the build machine during any cross-compilation that
REM may be necessary, depending on the platforms to be built.  These values in
REM these three variables should be surrounded by double quotes if they contain
REM spaces.
REM
REM There are a few other environment variables that impact the build process
REM when set ^(to anything^), they are:
REM
REM                        USE_AUTOCONF_MAKEFILE
REM
REM When set, the "autoconf" Makefile for MSVC will be used instead of the main
REM Makefile for MSVC.  It must exist at "%ROOT%\autoconf\Makefile.msc".
REM
REM                        NOCLEAN
REM
REM When set, the "clean" target will not be used during each build iteration.
REM However, the target binaries, if any, will still be deleted manually prior
REM to being rebuilt.  Setting this environment variable is only rarely needed
REM and could cause issues in some circumstances; therefore, setting it is not
REM recommended.
REM
REM                        NOSYMBOLS
REM
REM When set, copying of symbol files ^(*.pdb^) created during the build will
REM be skipped and they will not appear in the final destination directory.
REM Setting this environment variable is never strictly needed and could cause
REM issues in some circumstances; therefore, setting it is not recommended.
REM
REM                        NOMEMDEBUG
REM
REM When set, disables use of MEMDEBUG when building binaries for the "Debug"
REM configuration.
REM
REM                        BUILD_ALL_SHELL
REM
REM When set, the command line shell will be built for each selected platform
REM and configuration as well.  In addition, the command line shell binaries
REM will be copied, with their symbols, to the final destination directory.
REM
REM                        USE_WINV63_NSDKLIBPATH
REM
REM When set, modifies how the NSDKLIBPATH environment variable is built, based
REM on the WindowsSdkDir environment variable.  It forces this batch script to
REM assume the Windows 8.1 SDK location should be used.
REM
REM                        USE_WINV100_NSDKLIBPATH
REM
REM When set, modifies how the NSDKLIBPATH environment variable is built, based
REM on the WindowsSdkDir environment variable.  It causes this batch script to
REM assume the Windows 10.0 SDK location should be used.
REM
REM                        NMAKE_ARGS
REM                        NMAKE_ARGS_DEBUG
REM                        NMAKE_ARGS_RETAIL
REM
REM When set, these values are expanded and passed to the NMAKE command line,
REM after its other arguments.  These may be used to specify additional NMAKE
REM options, for example:
REM
REM                        SET NMAKE_ARGS=FOR_WINRT=1
REM                        SET NMAKE_ARGS_DEBUG=MEMDEBUG=1
REM                        SET NMAKE_ARGS_RETAIL=WIN32HEAP=1
REM
REM Using the above command before running this tool will cause the compiled
REM binaries to target the WinRT environment, which provides a subset of the
REM Win32 API.
REM
REM                        DLL_FILE_NAME
REM                        DLL_PDB_FILE_NAME
REM                        LIB_FILE_NAME
REM                        EXE_FILE_NAME
REM                        EXE_PDB_FILE_NAME
REM
REM When set, these values will override the associated target file name used
REM for the build.
