| 7 # This script takes libcmt.lib for VS2013 and removes the allocation related | |
| 8 # functions from it. | |

| 10 # Usage: prep_libc.py <VCLibDir> <OutputDir> <arch> [<environment_file>] | |
| 11 # | |
| 12 # VCLibDir is the path where VC is installed, something like: | |
| 13 # C:\Program Files\Microsoft Visual Studio 8\VC\lib | |
| 14 # | |
| 15 # OutputDir is the directory where the modified libcmt file should be stored. | |
| 16 # arch is one of: 'ia32', 'x86' or 'x64'. ia32 and x86 are synonyms. | |
| 17 # | |
| 18 # If the environment_file argument is set, the environment variables in the | |
| 19 # given file will be used to execute the VC tools. This file is in the same | |
| 20 # format as the environment block passed to CreateProcess. | |
