I'm resurrecting this old email, because I think a similar problem I'm having
is related, and am looking for more ways to dig into it.
In the perldl shell, PDL::AutoLoader doesn't complain (as I expect it to) if it
can't find a file to autoload. In particular if I do the following:
----------
pdl> $PDL::verbose=1
pdl> $PDL::debug=1
pdl> asdf()
AutoLoader: Expanding directories from .:.:+~/pdl:+./pdl...
AutoLoader: returning .,.,/Users/derek/pdl, <snip a whole bunch of
directories>,
Loading asdf.pdl ...I am here and $s is PDL AutoLoader: Undefined subroutine
asdf() cannot be autoloaded.
-----------
Where I have inserted a statement
print "I am here and \$s is $s\n"
to line 208 of Basic/AutoLoader.pm, right before the line
die $s."\tNo file `$func.pdl' was found in your \@PDLLIB path.\n";
It seems like the call to perl's die is getting executed, because a print
statement inserted after the die call does not get executed.
If I run the same thing as a one-liner I get the appropriate error:
--------
$ perl -MPDL::AutoLoader -e 'asdf();'
PDL AutoLoader: Undefined subroutine asdf() cannot be autoloaded.
No file `asdf.pdl' was found in your @PDLLIB path.
--------
***And if I run perldl in the debugger, I also get the desired error***
-------
$ perl -d perldl
__DB<1> n
##then press enter until it gets to the addhistory line around perldl:252
DB<2> use PDL::AutoLoader
DB<3> asdf()
PDL AutoLoader: Undefined subroutine asdf() cannot be autoloaded.
No file `asdf.pdl' was found in your @PDLLIB path.
-------
So it's not like AutoLoader is inherently broken, but rather something about
running perldl _NOT_ in the debugger is causing calls to perl's die() to not
print their messages.
I'm running a much simpler Perl installation now, since I accidentally wiped my
whole perl tree last weekend. So now the only PDL installed is 2.4.9_010. And
experiments with different ReadLine modules (Perl, Gnu) that Chris suggested
did not seem to help any. I don't see any $SIG{__DIE__} definitions in perldl,
but there are some elsewhere in the PDL source tree, but nothing looked likely
to me.
Any other ideas?
cheers,
Derek
