Subject: Re: [lfs-dev] LFS 7.10: 2.2. Host System Requirements: Perl
version
OK: module missing

Hi there,
am currently building a 7.10 from a very basic Ubuntu build host
that I had
debootstrapped.
For completeness, I did run the
version-check.sh
as I worked through the book and everything reported OK.
A bit further into the build, though, I was told that I didn't have
the
Getopt::Std.pm
module.
Easy enough to fix and whilst it might be "overkill" for the book,
which
probably assumes that folk have a build host that's not as stripped
down
as a debootstrapped OS install, it struck me that might be worth
adding
in an explicit check for that one Perl module ?
The file, AFAICT is /usr/lib/perl5/*/Getopt/Std.pm.
Why did you strip that out? This is essentially a library. We don't
search for every library that we need and Getopt/Std.pm is part of a
standard perl install.
I am against adding this to version-check.sh because it is too much
of an
edge case, but I am open to other opinions.
Can be useful in helping automate host-os requirements: strace'ing a
build shows - at least in theory - all that is accessed of host-os;
although strace can o/c interfere with what it's tracing.
I'm willing to do it if someone can show me a distro where a
apt-get/yum/dnf etc install of perl does not install Getopt::Std.pm.
In the same vein, I am thinking about removing the library consistency
check because that was a similar one-off problem where the solution
tends to confuse more than it helps.

This last example is a good one: there is a note about the presence or
absence of libgmp.la, libmpfr.la, etc, and also a shell script for
testing. I'd say that we could make notes about non-standard
configurations, but not write a test for them...

Pierre
