Re^3: access to ERRORLEVEL on Win32

Thanks for all your advice. Passing %ERRORLEVEL% as parameter is one workaround, but it would break the ease of implementation by using my script as filter. There obviously exits no way accessing %ERRORLEVEL% from perl without passing it as parameter, so things like

cmd /c "make  2>&1 | perl vcproj_filter.pl"
[download]

must be changed in batch file like

make > output.txt 2>&1
perl %ERRORLEVEL% output.txt"
[download]

Unfortunatly the following doesn't work:

cmd /c "make  > output.txt 2>&1 && perl %ERRORLEVEL% output.txt"
[download]

It seems if you start more then one process using && or | ERRORLEVEL is not set for each process but only for the last one. That's why using my script in a pipe and reading %ERRORLEVEL% would never work. I finally use a seperate perl script from where I make the call to make via system() and gather the return code from $?. The output is filtered afterwards.

Thanks for the help!

Have you considered an interface like `strace` and (the unix) `time`? `perl vcproj_filter.pl make all >output.txt 2>&1` [download] To launch the child, you'd use `system { $ARGV[0] } @ARGV` [download] The down side of this method is that the output of `make` and `vcproj_filter` will get mixed together.
