PDL users and developers- discussion welcome. --Chris
ACTION:
Add explicit dependencies to the git PDL Makefile.PL
for modules that are needed for essential PDL services.
That would make PDL builds more transparent, would
allow us to evaluate the impact on usage, and would
set us up better for the proposed factorization of
PDL into a core module component with external modules
providing key functionalities.
Then a PDL bundle(s) could be used to distribute the
modules.
DISCUSSION:
I tracked down a t/dumper.t test failure that
apparently resulted from a bug in the underlying
Data::Dumper module that has been fixed in more
recent versions of Data::Dumper.
Rather than hack around the bug, I reported the
problem to the Data::Dumper folks, and then added
Data::Dumper 2.122 as a prerequisite for PDL.
(This version appears to have the problem fixed)
The thought was that saving piddle data to files
was an essential capability of PDL and should be
fully supported rather than quietly skipped if
it did not build successfully. That is what we
do in many of the optional external dependencies
such as GSL, Minuit, PROJ4, OpenGL,...
After that addition, I was tracking down another
failure, in t/storable.t, and determined that we
actually use the basic Storable module and then
augment it to implement PDL::IO::Storable. We
appear to be requiring Storable but PDL::IO::Storable
will not work without it.
A grep through my blib/ got these modules being used:
Carp
Config
Convert::UU
Cwd qw(cwd abs_path);
Data::Dumper
DynaLoader
English
Exporter
ExtUtils::MakeMaker
File::Basename
File::Spec
FileHandle
Filter::Util::Call
Getopt::Long
IO::File
PGPLOT
POSIX qw( log10 );
Pod::PlainText
Pod::Text
SelfLoader
Storable
Symbol qw/ gensym /;
Text::Balanced
Tk
in some .pm file. Some of these are provided by the
core perl modules, others may be used conditionally.
The proposal is to put everything that is actually
used (required?) into the prerequisites list and see
how things work from there. Things that are not
necessarily required should be listed as a perldl.conf
option so we are all clear.
