Are you running the PDL that comes with Debian or your own build? What's the output of perldoc -l PDL I do not have this problem on my private build of 2.4.3 on either Debian Etch (4.0) x86_64 and Debian Sarge (3.1) i686. % perl -MPDL -MPDL::Complex -le '$x = r2C(-27); $r = Croots $x, 3; print $r;' [1.5 +2.59807621135332i -3 +3.67394039744206e-16i 1.5 -2.59807621135332i]

Subject:

cannot determine PDL-2.4.3 errors from reports to date

Hi Casiano, None none of the attachments here or in the e-mails have any error messages in them. (Even the initial problem with complex stringification does not show an error message in the report, just what may be part of a warning. I think that specific issue has been fixed in CVS)) If you can generate output with an error message from the PDL build and install, I will take another look. Here is what I do for a really clean PDL install: 1. untar the distribution into a directory 2. cd PDL-2.4.3 3. perl Makefile.PL 2>&1 | tee -a ../pdl-build-log.txt 4. make 2>&1 | tee -a ../pdl-build-log.txt 5. make test 2>&1 | tee -a ../pdl-build-log.txt At this point, if tests have passed then PDL was built correctly. You should be able to do 6. perl -Mblib perldl which starts the perldl shell where you can run demo or perform interactive PDL computations. Best wishes and sorry I could not help more. --Chris On Fri Jun 27 04:10:41 2008, casiano.rodriguez.leon@gmail.com wrote: Show quoted text

Mmm ... yes I guess the problem is the version of Debian I have, not PDL. I am trying now to install it from CPAN ... I'll let you know the result when finishes ... Casiano

Stringify problem for PDL::Complex items

This problem has been resolved in cvs for the forthcoming PDL-2.4.4 release. Please follow up via the sourceforge bug tracker for PDL accessible from http://sourceforge.net/projects/pdl/ where you will have a much faster response than on from bugs.cpan.org where the tickets are not immediately visible.
