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 Finally, the NCRTLIBPATH and NSDKLIBPATH environment variables may be set
REM to specify the location of the CRT and SDK, respectively, needed to compile

REM executables native to the architecture of the build machine during any
REM cross-compilation that may be necessary, depending on the platforms to be
REM built.  These values in these two variables should be surrounded by double
REM quotes if they contain spaces.
REM
REM Please note that the SQLite build process performed by the Makefile
REM associated with this batch script requires both Gawk ^(gawk.exe^) and Tcl
REM 8.5 ^(tclsh85.exe^) to be present in a directory contained in the PATH
REM environment variable unless a pre-existing amalgamation file is used.

REM
REM In the example above, "C:\dev\sqlite\core" represents the root of the

REM
REM Please note that the SQLite build process performed by the Makefile

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                        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                        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
REM When set, the value is expanded and passed to the NMAKE command line, after
REM its other arguments.  This is used to specify additional NMAKE options, for
REM example:

** Each such SQL comment is printed as it is encountered.  A separate 
** in-memory SQLite database is created to run each chunk of SQL.  This
** feature allows the "queue" of AFL to be captured into a single big
** file using a command like this:
**
**    (for i in id:*; do echo '|****<'$i'>****|'; cat $i; done) >~/all-queue.txt
**
** (Once again, change the "|" to "/") Then all elements of the AFL queue
** can be run in a single go (for regression testing, for example) by typing:
**
**    fuzzershell -f ~/all-queue.txt >out.txt
**
** After running each chunk of SQL, the database connection is closed.  The
** program aborts if the close fails or if there is any unfreed memory after
** the close.
