Subject: Errors redirecting STDERR on Windows XP SP3
Download (untitled) / with headers
text/plain 1.6k
Hi, Despite the successes on Win32 on CPAN Testers, IPC::Exe is failing tests on a Windows XP SP3 system running strawberry Perl 5.18.2. In particular, it seems to be failing tests which read or redirect STDERR. I've attached a log of the errors and of the results of running 'perl -v'. I've reduced the code to that in the attached file. If run as perl -s try.pl -output=stdout the child process will write to stdout with no capturing. This results in: ------------------------------------------------- line1 line2 line3 ------------------------------------------------- which is expected. Capturing stdout via perl -s try.pl -output=stdout -capture_stdout results in ------------------------------------------------- $VAR1 = { 'stdout' => [ 'line1 ', 'line2 ', 'line3 ' ] }; ------------------------------------------------- which is also expected. Output to stderr works: perl -s try.pl -output=stderr ------------------------------------------------- line4 line5 line6 ------------------------------------------------- but capturing to stderr doesn't: ------------------------------------------------- $VAR1 = { 'stderr' => [] }; ------------------------------------------------- Weirder, outputing to stdout and capturing stderr does not work: ------------------------------------------------- $VAR1 = { 'stderr' => [] }; ------------------------------------------------- All of the above work as expected on a Linux box. I know little to nothing about Windows, but I'm willing to poke at it if given directions. Thanks, Diab

Sorry, I forgot a couple of command lines in the first message: Output to stderr and capturing of stderr doesn't work: perl -s try.pl -output=stderr -capture_stderr ------------------------------------------------- $VAR1 = { 'stderr' => [] }; ------------------------------------------------- Output to stdout and capturing of stderr does not work: perl -s try.pl -output=stdout -capture_stderr ------------------------------------------------- $VAR1 = { 'stderr' => [] }; ------------------------------------------------- The output to stdout has disappeared.
