I have got the source code from the trunk, "make test" mostly passed except for a threading issue, but I installed it anyway.
Tried to load a test module, but it fails with the following error: # Error: Can't load '/usr/local/lib/perl5/site_perl/5.20.2/x86_64-linux-thread-multi/auto/APR/APR.so' for module APR: /usr/local/lib/perl5/site_perl/5.20.2/x86_64-linux-thread-multi/auto/APR/APR.so: undefined symbol: ap_strchr at /usr/local/lib/perl5/5.20.2/x86_64-linux-thread-multi/DynaLoader.pm line 193. # at /usr/local/lib/perl5/site_perl/5.20.2/x86_64-linux-thread-multi/APR/Table.pm line 23. The following test module loads OK, but fails if I uncomment any of the "use APR::*" lines: #------------------------------------------------------------------------- package mytest::mytestmodule; use 5.010001; use strict; use warnings; use Carp; $SIG{__DIE__} = \&Carp::confess; use mod_perl2; use Apache2::Connection(); use Apache2::RequestRec(); use Apache2::SubRequest(); use Apache2::Access(); use Apache2::RequestUtil(); use Apache2::Response(); use Apache2::Log(); use Apache2::Util(); use Apache2::Const ("-compile", qw(:common :methods :satisfy :auth MODE_READBYTES)); use Apache2::URI(); use Apache2::Filter (); #use APR::Const ("-compile", qw(:common SUCCESS BLOCK_READ)); use IO::Socket qw(SOCK_STREAM); use Data::Dumper; use AnyDBM_File (); #use APR::Brigade (); #use APR::Bucket (); #use APR::Base64 (); #use APR::Table (); #use APR::URI (); use URI::Escape::XS qw/uri_escape uri_unescape/; #use Apache2::MPM(); our $VERSION = '1.0.1'; 1; __END__ #------------------------------------------------------------------------- -------------8<---------- Start Bug Report ------------8<---------- 1.
