Re^6: FindBin works different on Fedora Core 2?

It's perl 5.8.3 in both cases, as you say -- just to be sure, let's verify that. Ensure that each executable is the version you think it is

Verified. Both return 5.8.3 from 'perl -v'. However, the one on Fedora2 was built for i386-linux-thread-multi and the one on Fedora1 was build for i686-linux. I don't know why that would effect FindBin...

Second, check your %INC hash.

Done. Both %INC hashes are identical. Both scripts load the same modules from the same places, all within the 5.8.3 base module tree.

Third -- and this is not likely but possible -- check that your perls are actually using version numbering on their system library directories

Checked. Both are using 5.8.3 in their module paths.

then I will join you in being stumped.

Welcome to the club. I guess I'll just fix it and move on... I've got a nasty seg-fault to track down anyway.

I don't know why that would effect FindBin... I really think this has to do with the `abs_path()` implementation in Cwd.pm. Much of Cwd, including the `abs_path()` functionality, is written as XS and therefore lives down in arch-specific directories. Somehow the versions in each of your arch directories differ. Finally, in the Changes file, I note the following (I don't know if it's pertinent to your situation): `2.15 Fri Jan 16 08:09:44 CST 2004 + - Fixed a problem on static perl builds - while creating Makefile.aperl, it was loading a mismatched version of Cwd from blib/ .` [download] shrug Matt Update: I could be barking up the wrong tree here. In the versions I've been playing with, the following statements are in FindBin.pm: `FindBin.pm version 1.43 # Get absolute paths to directories $Bin = abs_path($Bin) if($Bin); $RealBin = abs_path($RealBin) if($RealBin);` [download] `FindBin.pm version 1.44 # Get absolute paths to directories $Bin = abs_path($Bin) unless (!$Bin \|\| File::Spec->file_na +me_is_absolute($Bin)); $RealBin = abs_path($RealBin) unless (!$RealBin \|\| File::Spec->fi +le_name_is_absolute($RealBin));` [download] In the first case, `abs_path()` is being invoked, whereas in the second case, it is not. The conditionals have changed.	[reply] [d/l] [select]

Update: I could be barking up the wrong tree here. In the versions I've been playing with, the following statements are in FindBin.pm:

FindBin.pm version 1.43

     # Get absolute paths to directories
     $Bin     = abs_path($Bin)     if($Bin);
     $RealBin = abs_path($RealBin) if($RealBin);
[download]

FindBin.pm version 1.44

     # Get absolute paths to directories
     $Bin     = abs_path($Bin)    unless (!$Bin || File::Spec->file_na
+me_is_absolute($Bin));
     $RealBin = abs_path($RealBin) unless (!$RealBin || File::Spec->fi
+le_name_is_absolute($RealBin));

abs_path()
