bug#20497: GuixSD installation - Build of system.drv failed

2015-05-05 Thread Jeffrey Serio
Hello,

Thank you for your reply.  The GuixSD version is 0.8.1.  I figured part of the 
problem was with libarchive not 
being the pre-built binary.  I even tried reassuring that hydra was authorized, 
which apparently had no effect 
on the outcome.  Also, while using Guix as a package manager on my host system 
(Fedora 21), I attempted to 
install the package 'dfc' from source (not binary) and I encountered the 
libarchive-3.1.2.drv error there as well, so I checked the build log located at 
/tmp/nix-build*-libarchive-3.1.2.drv/.../test_option_b.log, and it mentioned 
that "File archive1.tar has size 
3072, expected 2048" and that "bsdtar does not pad archives written directly to 
regular files".  I hope this 
information helps narrow down the issue.  Do you have any suggestions as to how 
this could be resolved?

Best Regards,
Jeffrey

One problem is that hydra.gnu.org didn’t keep the pre-built binaries.
We ought to fix it, but our current server is quite limited in resources
(hopefully we will change it soon.)

As for the exact build issue, I don’t know.  You may be able to work
around it by running ‘guix pull’ right before running ‘guix system init’
in the installation image (likewise on your Fedora system: just run
‘guix pull’ before trying to install software.)

Besides, note that 0.8.2 will hopefully be released within two weeks.

Indeed.  Run guix to install a package should make it available
immediately.  Currently, we have 'PATH=~/.guix-profile/bin' in
profile and print hint for additional variables.
(Note that when profile changes, even we build all variables with the
location they going to be, a hint or re-source is still needed when the
new profile bring new variables.)

How about using a shell variable as input for the location:
(replace /gnu/store/xxx with $GUIX_PROFILE)

  # etc/profile
  export PATH=$GUIX_PROFILE/bin:$PATH
  export MANPATH=$GUIX_PROFILE/share/man:$MANPATH
  ...

Then when 'source' it, we pass the location:
(we did know where $GUIX_PROFILE is when do the 'source')

  # ~/.bash_profile
  GUIX_PROFILE=$HOME/.guix-profile
  if [ -f $GUIX_PROFILE/etc/profile ]; then
. $GUIX_PROFILE/etc/profile
  fi

  # /etc/profile
  GUIX_PROFILE=/run/current-system/profile
  source $GUIX_PROFILE/etc/profile

Yes, but we would also like users to be able to source
~/.guix-profile/etc/profile themselves directly, and it wouldn’t be nice
to ask them to set GUIX_PROFILE before sourcing it.
