Perl Digest::SHA1 not being imported on OS X Leopard Server

Question

Hi there,

I've been trying to get SVN to connect to Atlassian Crowd for authentication but have been running into issues with OS X Leopard Server (10.5.8) and Perl's Digest::SHA1.

I've installed it from the source (http://search.cpan.org/~gaas/Digest-SHA1-2.12/SHA1.pm) and if I call it directly from a Perl script it works fine, but in my apache logs I get this error:

failed to resolve handler `Apache::CrowdAuth': Can't load '/Library/Perl/5.8.8/darwin-thread-multi-2level/auto/Digest/SHA1/SHA1.bundle' for module Digest::SHA1: dlopen(/Library/Perl/5.8.8/darwin-thread-multi-2level/auto/Digest/SHA1/SHA1.bundle, 1): no suitable image found.  Did find:

Unfortunatley there doesn't seem to be any documentation on the error online.

Any ideas?

Answer 1

It seems that there is a mismatch in the compiler architecture triplet between modperl and the Perl executable. The relevant error is really just the "no matching architecture in universal wrapper", which seems to be completely OS X specific.

Are you using MacOS perl? Try building and installing a different perl, it is known that Apple did a terrible job in their perl build.

Answer 2

While looking for links to show Ether, I found this post which may be relevant. It's a bit old, but the mention of Apache caught my eye, since it's part of your problem:

If you've recently migrated from a 32-bit Mac to a 64-bit model, you may have run into problems with some of your Perl modules suddenly throwing up their hands and going "wha?" An AFP548 article points out the likely culprit: CPAN on the Mac compiles all of your modules as Universal 32-bit binaries by default, which tends to disappoint 64-bit applications such as Apache 2.0's mod_perl.

The fix mentioned there is to adjust your ARCHFLAGS variable. The Ars Technica post points to this link for more.
