Question

i want to make VS copy the .lib-file it created after the build process to a specific folder.
So i went to the project config, post-build event, and entered the following command:

if exist $(TargetPath)
xcopy "$(TargetPath)" "C:\Users\Incubbus\Documents\Visual Studio 2010\My Libraries\z.lib" /Y

But instead of copying the process fails after i click “build” and i receive the following error:

error MSB3073: The command “if exist
C:\Users\Incubbus\Documents\Visual Studio 2010\My
Libraries\MyNetWorkProject\Debug\IncNetworkLibD.lib xcopy
“C:\Users\Incubbus\Documents\Visual Studio 2010\My
Libraries\MyNetWorkProject\Debug\IncNetworkLibD.lib”
“C:\Users\Incubbus\Documents\Visual Studio 2010\My Libraries\z.lib” /Y

:VCEnd” exited with code 2.

I am also wondering about the :VCEnd in the command-string of the error message <- Maybe this is the reason? How to get this solved?

Any help and hints would be happily consumed :)…

partial solution:

EDIT: it looks like the renaming part (Inc.lib to z.lib) makes trouble, when xcopy asks whether this is a file or a directory…it works when i just copy the originally named file to a directory instead of copying renamed

Xcopy documentation says the following:

Specifying whether Destination is a file or directory
If Destination does not contain an existing directory and does not end with a backslash (\), the following message appears:

Does destination specify a file name 
or directory name on the target 
(F = file, D = directory)? 

Press F if you want the file or files to be copied to a file. Press D if you want the file or files to be copied to a directory.

You can suppress this message by using the /i command-line option, which causes xcopy to assume that the destination is a directory if the source is more than one file or a directory.

You need the opposite, but there is no such switch.

The solution is proposed here: https://stackoverflow.com/a/4283533/532647.

It is suggested to prepend the xcopy command with echo f | prefix, which basically does the following: it simulates a user pressing f key when xcopy asks.

So your command should look like:

if exist $(TargetPath)
echo f | xcopy "$(TargetPath)" "C:\Users\Incubbus\Documents\Visual Studio 2010\My Libraries\z.lib" /Y

Operator | just pipes the output of echo f (== f) into xcopy command and it is read when appropriate. More information about output redirection here: http://ss64.com/nt/syntax-redirection.html.

UPDATE:
As Govert points out, this hack won’t work under a localized version of Windows.
However, another hack will work:

xcopy D:\file.zip c:\renamedFile.zip*

Appending destination file name with an asterisk * makes xcopy not ask whether destination is a file or a directory.
