:Usage

echo.%~nx0 [flags and arguments] [quoted MSBuild options]

echo.

echo.Build CPython from the command line. Requires the appropriate

echo.version(s) of Microsoft Visual Studio to be installed (see readme.txt).

echo.

echo.After the flags recognized by this script, up to 9 arguments to be passed

echo.directly to MSBuild may be passed. If the argument contains an '=', the

echo.entire argument must be quoted (e.g. `%~nx0 "/p:PlatformToolset=v100"`).

echo.Alternatively you can put extra flags for MSBuild in a file named

echo.`msbuild.rsp` in the `PCbuild` directory, one flag per line. This file

echo.will be picked automatically by MSBuild. Flags put in this file does not

echo.need to be quoted. You can still use environment variables inside the

echo.response file.

echo.

echo.Available flags:

echo. -h Display this help message

echo. -V Display version information for the current build

echo. -r Target Rebuild instead of Build

echo. -d Set the configuration to Debug

echo. -E Don't fetch or build external libraries. Extension modules that

echo. depend on external libraries will not attempt to build if this flag

echo. is present; -e is also accepted to explicitly enable fetching and

echo. building externals.

echo. -m Enable parallel build (enabled by default)

echo. -M Disable parallel build

echo. -v Increased output messages

echo. -k Attempt to kill any running Pythons before building (usually done

echo. automatically by the pythoncore project)

echo. --pgo Build with Profile-Guided Optimization. This flag

echo. overrides -c and -d

echo. --test-marker Enable the test marker within the build.

echo.

echo.Available flags to avoid building certain modules.

echo.These flags have no effect if '-e' is not given:

echo. --no-ssl Do not attempt to build _ssl

echo. --no-tkinter Do not attempt to build Tkinter

echo.

echo.Available arguments:

echo. -c Release ^| Debug ^| PGInstrument ^| PGUpdate

echo. Set the configuration (default: Release)

echo. -p x64 ^| Win32

echo. Set the platform (default: Win32)

echo. -t Build ^| Rebuild ^| Clean ^| CleanAll

echo. Set the target manually

echo. --pgo-job The job to use for PGO training; implies --pgo

echo. (default: "-m test --pgo")

exit /b 127
