# This script takes libcmt.lib for VS2013 and removes the allocation related
|
|
# functions from it.
|
|
#
|
|
# Usage: prep_libc.py <VCLibDir> <OutputDir> <arch> [<environment_file>]
|
|
#
|
|
# VCLibDir is the path where VC is installed, something like:
|
|
# C:\Program Files\Microsoft Visual Studio 8\VC\lib
|
|
#
|
|
# OutputDir is the directory where the modified libcmt file should be stored.
|
|
# arch is one of: 'ia32', 'x86' or 'x64'. ia32 and x86 are synonyms.
|
|
#
|
|
# If the environment_file argument is set, the environment variables in the
|
|
# given file will be used to execute the VC tools. This file is in the same
|
|
# format as the environment block passed to CreateProcess.
