/appl/web/compile/HTML-Embperl-1.3.6/blib/arch/auto/HTML/Embperl/Embperl.so
is being built with a format that perl does not understand and so cannot dynamically load. Either the Embperl compile configuration is wrong, perl is compiled with the wrong dynamic loader, or there's a problem in the system's compiler setup. What you have is not a C problem, but rather an object file format problem. Some C programmers would be more familiar with it than you are, and many would at least understand the situation a bit better (although not necessarily what to do about it), but I do know quite a few that would be as clueless as you were upon seeing it the first time. Systems administrators, on the other hand, should be more likely to able to recognize that situation and deal with it. However, it is still an unusual problem[1], so finding someone even within that skillset could be a challenge. Probably your best bet would be an AIX-specific perl list, or, failing that, a general perl list. Note that the only AIX I've used was 4.1.2, and I only went so far as to work with some ksh scripts there, so I cannot help you more than this. I wish I could be more helpful, but that's all I'm able to offer. Ed [1] Normally, all of the compilation tools on a system are consistent in their file formats, such that the error described below only happens on attempts to use a binary compiled on a different OS or OS version. For example, one could get that same error when trying to use an Embperl.so compiled for Linux on a Solaris system. It is possible to get it on a correctly configured system by specifying an incorrect target system, but most of the time one doesn't specify a target system at all. On Thu, 8 Jul 2004, John P.
