PERL_DL_NONLAZY=1

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I've got a module (DBD::Informix) that doesn't load when the PERL_DL_NONLAZY environment variable is set. The linking fails: missing symbol name is simply `stat' (!).

What is the effect of the PERL_DL_NONLAZY flag, where is it documented, and how can I prevent ExtUtils::MakeMaker from setting it?

Here is the output; note that the Informix libraries, which it is trying to link, are listed in /etc/ld.so.conf.

[root@apollo root]# PERL_DL_NONLAZY=1 perl -MDBD::Informix
Can't load '/usr/lib/site_perl/5.6.1/i686-linux-thread-multi/auto/DBD/

this thread might be interesting to you, in particular... PERL_DL_NONLAZY causes unresolved symbols in the .so file to be error a load time rather than when called. UPDATE: Here's another great link curtosy of google And another particularly crafty search	[reply]
