From 4df3f71782256c7a90f9a7445f093a545fcaa1b1 Mon Sep 17 00:00:00 2001 From: Mark H Weaver Date: Mon, 11 Feb 2013 19:13:32 -0500 Subject: [PATCH 2/2] Improve shell script headers and pre-inst-env handling. * pre-inst-env.in: Define $GUIX_UNINSTALLED. * guix-build.in, guix-download.in, guix-gc.in, guix-import.in, guix-package.in: Rewrite shell script headers to adjust '%load-path' and '%load-compiled-path' within Guile itself instead of setting environment variables. Inhibit this behavior if $GUIX_UNINSTALLED is set to a non-empty string. --- guix-build.in | 22 ++++++++++++++++------ guix-download.in | 22 ++++++++++++++++------ guix-gc.in | 24 +++++++++++++++++------- guix-import.in | 22 ++++++++++++++++------ guix-package.in | 24 +++++++++++++++++------- pre-inst-env.in | 7 ++++++- 6 files changed, 88 insertions(+), 33 deletions(-) diff --git a/guix-build.in b/guix-build.in index f8c7115..6b79962 100644 --- a/guix-build.in +++ b/guix-build.in @@ -1,15 +1,25 @@ #!/bin/sh # aside from this initial boilerplate, this is actually -*- scheme -*- code +script=guix-build + prefix="@prefix@" datarootdir="@datarootdir@" +moduledir="@guilemoduledir@" -GUILE_LOAD_COMPILED_PATH="@guilemoduledir@:$GUILE_LOAD_COMPILED_PATH" -export GUILE_LOAD_COMPILED_PATH - -main='(module-ref (resolve-interface '\''(guix-build)) '\'guix-build')' -exec ${GUILE-@GUILE@} -L "@guilemoduledir@" -l "$0" \ - -c "(apply $main (cdr (command-line)))" "$@" +start=" +(let () + (define (main interp guix-uninstalled-str module-dir script-file . args) + (let* ((guix-uninstalled?
