Troubleshooting GNU Guix

-- mode: org; coding: utf-8; --

Running out of disk space

Use the TMPDIR environment variable to use a different directory when building files. Use it with the daemon.

Libraries links (seen with ldd) are pointing outside /gnu/store

When copying the files from one /gnu to another /gnu store they work fine, e.g.

    /gnu/store/nx4zd42igyb7ghmv4mxv6ncg8wr7ypa1-bash-4.3.33/bin/bash --version
    GNU bash, version 4.3.33(1)-release (x86_64-unknown-linux-gnu)

but when I run

    /gnu/store/wnsbzddp3izv3xr3gqf2rar4fyd4shl7-guix-0.8.1.f1082ec/bin/guix package -i bash

it runs and I get

    The following package will be installed:     
       bash 4.3.33  /gnu/store/7cc229218glj3kzp6zafzs5mc4241wqk-bash-4.3.33

    guix package: error: build failed: unexpected EOF reading a line

Looking at

    head -1 /gnu/store/wnsbzddp3izv3xr3gqf2rar4fyd4shl7-guix-0.8.1.f1082ec/libexec/guix/substitute-binary
#!/gnu/store/nx4zd42igyb7ghmv4mxv6ncg8wr7ypa1-bash-4.3.33/bin/bash

it calls bash and now check

    /gnu/store/nx4zd42igyb7ghmv4mxv6ncg8wr7ypa1-bash-4.3.33/bin/bash
    bash: /gnu/store/nx4zd42igyb7ghmv4mxv6ncg8wr7ypa1-bash-4.3.33/bin/bash: No such file or directory

while

    ldd /gnu/store/nx4zd42igyb7ghmv4mxv6ncg8wr7ypa1-bash-4.3.33/bin/bash
        linux-vdso.so.1 =>  (0x00007fff739ec000)
        libreadline.so.6 => /gnu/store/fznw2a1ig05jkc2yrw8knzcb99akcjx7-readline-6.3/lib/libreadline.so.6 (0x00007f0084bd5000)
        libhistory.so.6 => /gnu/store/fznw2a1ig05jkc2yrw8knzcb99akcjx7-readline-6.3/lib/libhistory.so.6 (0x00007f00849cc000)
        libncursesw.so.5 => /gnu/store/ksnhghfy6hkk8mmxd4nacyd8c1smdp6p-ncurses-5.9/lib/libncursesw.so.5 (0x00007f008476a000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f008455b000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f008419b000)
        /gnu/store/q2mm1wv4a3g0b29yv0rjybfjh8kr07qi-glibc-2.20/lib/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00007f0084e1d000)

Oooops. Where does libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 come from?

Also the other bash stopped working

    /gnu/store/nx4zd42igyb7ghmv4mxv6ncg8wr7ypa1-bash-4.3.33/bin/bash --version

and ldd shows links outside /gnu (when it worked they are all linked inside /gnu).

Also the guix binary stopped working. Same issue.

Can anyone explain this? I tried multiple USB images and it is all the same.

The explanation is that GNU Guix has metadata in the sqlite data base under /var/guix. You need to copy that with the store.
