LilyPond

[thomas-morgan]

With NixOS 15.09 I get this error running LilyPond:

$ /run/current-system/sw/bin/lilypond
GNU LilyPond 2.18.2
warning: not relocating, no 2.18.2/ or current/ found under /run/current-system/sw/share/lilypond/
ERROR: In procedure primitive-load-path:
ERROR: Unable to find file "lily.scm" in load path

I can work around this (clumsily) by using an old version of wrapProgram in LilyPond's postInstall. This wrapProgram differs by not including -a "$0".

postInstall = ''
  wrapProgram() {
    local prog="$1"
    local hidden="$(dirname "$prog")/.$(basename "$prog")"-wrapped
    mv $prog $hidden
    makeWrapper $hidden $prog "$@"
  }

  for f in "$out/bin/"*; do
      wrapProgram "$f" --set GUILE_AUTO_COMPILE 0 \
                       --set PATH "${ghostscript}/bin"
  done
'';

This seems to be related to #9562. Changing argv[0] apparently can break some users of wrapProgram as well as those of makeWrapper.

Hmm, perhaps we should add --no-argv0 or some similar option to handle these cases easily?

It's better to set --argv0 "$f" in most cases, which I just did in master and release-15.09.
