Thanks. Too bad I cannot speak Perl. Here's the info: [root at mail]# uname -a Linux mail.greenspot.fi 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 05:09:20 EDT 2010 i686 i686 i386 GNU/Linux [root at mail]# rpm -q perl-Compress-Raw-Zlib perl-IO-Compress perl-IO-Compress-Zlib perl perl-Compress-Raw-Zlib-2.030-1.el5.rf perl-IO-Compress-2.030-2.el5.rf package perl-IO-Compress-Zlib is not installed perl-5.8.8-32.el5_5.2 [root at mail tiina]# This could be caused by something in Openwebmail. I found info that whenever memGzip is not successful, it returns undef - this probabvly means "undefined subroutine", which is what Openwebmail now tells me. http://search.cpan.org/~pmqs/IO-Compress-2.030/lib/Compress/Zlib.pm Maybe this will help - here is the offending Openwebmail function: sub httpprint { my ($r_headers, $r_htmls)=@_; if (is_http_compression_enabled()) { my $zhtml=Compress::Zlib::memGzip(join('',@{$r_htmls})); if ($zhtml ne '') { print httpheader(@{$r_headers}, '-Content-Encoding'=>'gzip', '-Vary'=>'Accept-Encoding', '-Content-Length'=>length($zhtml)), $zhtml; return; } } my $len; foreach (@{$r_htmls}) { $len+=length($_); } print httpheader(@{$r_headers}, '-Content-Length'=>$len), @{$r_htmls}; return; } - Jussi On 12.10.2010 10.01, David Hrbáč wrote: > Dne 12.10.2010 8:28, Jussi Hirvi napsal(a): >> After system update yesterday, Openwebmail now gives an error: >> >>> Undefined subroutine&Compress::Zlib::memGzip called at /var/www/cgi-bin/openwebmail/shares/ow-shared.pl line 1175. >> >> I tried to do >> >> perl -MCPAN -e shell >> install Compress::Zlib >> >> But it says Compress::Zlib is up-to-date.
