Is there any rollback during installation when I see that the installation
/ build test of a PDL-3.000 version fails?
Or can I install various PDL versions in parallel (the new one for build
tests but keeping the recent 2.4.9 / 2.4.11 installation)?
If you're building PDL from source you could install PDL-3.000 by starting
with (eg):
perl Makefile.PL INSTALL_BASE=C:/experimental
Then 'make install' will install PDL-3.000 into C:/experimental.
If you then want to use that PDL-3.000 with your perl, you either need to
begin your perl scripts with:
use lib 'C:/experimental/lib/perl5';
or
set your PERL5LIB environment variable to C:/experimental/lib/perl5
If you do neither of those things, then PDL-3.000 will not be found, and
perl will use the existing 2.4.9/2.4.11 installation.
Achieving the same via a PPM installation entails extra hoops through which
to jump.
The same approach as outlined above would work .... but how does one 'ppm
install' into a 'C:/experimental' tree (or any other non-standard location)
?? That's the tricky part.
What's the deadline? When do you - for latest - need feedback from tests?
The sooner the better.
We keep a fairly close eye on PDL (as regards the test suite) for Windows -
but who knows what problems we might miss.
When it comes to testing, it's a case of "the more, the better" - so if
you're thinking of doing some testing, just grab the latest PDL devel
release (2.004011_011) from CPAN, give it a try and please let us know of
any problems you uncover.
Cheers,
Rob
