Failed with exit code 65280.
in [Perl]

From: lbo_user on 26 Nov 2007 10:54 Hi all, I've had a look around but haven't managed to find any info on this particular problem. Maybe I was searching for the wrong stuff. Anyway, I have a script that runs the flac and lame tools to convert between FLAC and MP3. Within the script the variable $convert_command contains the full piped command with file pathnames etc. This is called using system() but it always fails with exit code 65280 and the warning, "Can't init outfile 'my_outfile'". However, when I run the same command from the shell everything is fine and the file is written. The destination is writable by all. There don't seem to be any permissions problems. What am I missing? Thanks.

Without seeing your code it's difficult to do more than guess, but one thing I would do is double-check the value of $convert_command, to make absolutely certain it's right. With Perl and shells interpolating variables into strings, and sharing many of the same escape sequences in quoted string constants, that's an easy place for bugs to sneak in. Also, the return value from system() isn't just the return value of the called command; it's that, plus some other stuff. You need to jump through a few hoops to get the actual exit status, as shown in "perldoc -f system": You can check all the failure possibilities by inspecting $? like this: if ($? == -1) { print "failed to execute: $!\n"; } elsif ($? & 127) { printf "child died with signal %d, %s coredump\n", ($? & 127), ($? & 128) ? 'with' : 'without'; } else { printf "child exited with value %d\n", $? >> 8; } Once you get the real exit code from the tool you're calling, then you can find the meaning of that code (and the accompanying "Can't init" message) in the tool's docs. sherm-- -- WV News, Blogging, and Discussion: http://wv-www.com Cocoa programming in Perl: http://camelbones.sourceforge.net
From: lbo_user on 27 Nov 2007 15:41 OK, thanks for the help so far. Here's some more detail and the code itself. I'm running a script that transcodes FLAC to MP3 hence it calls both the flac and lame executables with the relevant options and file paths. The script tries to create a mirrored directory structure of the source flac tree. You can get the code here: http://robinbowes.com/projects/flac2mp3 I've been in touch with the author but he doesn't have an OS X machine to test on. It seems to work fine on Windows and possibly Linux. If you look at the script, the parts to search for are $convert_command which is a concatenation of tools, arguments and paths, and the variable $tmpfilename which is the temp destination filename that it fails to write. Having added Sherman's code to get the actual error, running the script returns the following: [macbaddy:~] sjalloq% flac2mp3.pl /Volumes/FreeNAS/MEDIA/FLAC /Volumes/ FreeNAS/MEDIA/MP3_new Using flac from: /usr/local/bin/flac Using lame from: /usr/local/bin/lame Processing directory: /Volumes/FreeNAS/MEDIA/FLAC 1546 flac files found.

"flac" --decode ... ^ ^ ????? And it works perfectly when you run it from the command line? Run the flac command, redirect output to a file, maybe there's something in there? If that works, then redirect that file to the lame command. If there's a verbose option to those, then try that. It's not a perl problem, so focus on something else. > failed with exit code 65280 |
