Hi Guix,
I have a very weird problem that I don't understand. "./pre-inst-env
guix build" just sits there doing nothing at all:
[rwurmus@guix-builder:/localhome/rwurmus-tmp/guix] (531) $ git describe HEAD
v0.8.1-1597-g4702cec
[rwurmus@guix-builder:/localhome/rwurmus-tmp/guix] (532) $ time ./pre-inst-env guix build texlive-texmf-2014
The following file will be downloaded:
/gnu/store/h1qjkg8bvcdb485q81lw5844szgywpg7-texlive-texmf-2014
^C
real 13m0.888s
user 0m3.728s
sys 0m0.364s
Now using the previously "sudo make install"'d version of Guix:
[rwurmus@guix-builder:/localhome/rwurmus-tmp/guix] (533) $ time guix build texlive-texmf-2014
guix build: warning: failed to load '(gnu packages ld-wrapper)':
ERROR: no code for module (gnu packages ld-wrapper)
/gnu/store/0zx4rfbf58s0fnh4nzcaajdrfwb1ilv5-texlive-texmf-2014
real 0m24.060s
user 0m4.004s
sys 0m0.541s
I can't really say when I last make install'd, but it was probably
around commit 27350ef8b.
I have a feeling I should do "make clean" again and purge everything,
but I thought I should report this anyway. I should also note that I
develop Guix on a different machine with the *same* network-mounted home
directory. On guix-builder I make and make install everything from
within a directory on a local disk, but my actual home directory is the
network share, so I suspect that this could all be explained by sharing
some go caches or so. Could someone please confirm that this is in fact
what's happening?
~~ Ricardo

(Side note: there’s a stale ld-wrapper.scm file here, hence the warning.
The problem with repeated ‘make install’ is that files are left behind.)

Uh, I can’t reproduce it. Could you try:
./pre-inst-env strace -o log guix build texlive-texmf
to see where it’s stuck?
Another issue: 24 seconds is really a *lot*, esp. if there was nothing
to build. Where did those 20 seconds between user and real time go?
Could it be due to a very slow file system? Is the daemon socket file
stored on NFS? (Does that even work?)

The .go files are loaded either from $prefix or from $builddir (when
using ./pre-inst-env.) If these are on NFS, that certainly slows things
down, but I don’t think there are other side effects.
HTH,
