From bf91e6835d21e3bd7b49bb85b40f61389604c6f7 Mon Sep 17 00:00:00 2001 From: Marius Bakke Date: Wed, 22 Aug 2018 16:22:36 +0200 Subject: build-system/meson: Strip RUNPATH and remove PatchELF traces. * guix/build-system/meson.scm (%meson-build-system-modules): Don't import (guix build rpath). * guix/build/meson-build-system.scm (fix-runpath): Rename to ... (shrink-runpath): ... this. Update docstring. Remove AUGMENT-RPATH calls and related code. (%standard-phases): Add 'shrink-runpath'. --- guix/build/meson-build-system.scm | 52 ++++++--------------------------------- 1 file changed, 7 insertions(+), 45 deletions(-) (limited to 'guix/build') diff --git a/guix/build/meson-build-system.scm b/guix/build/meson-build-system.scm index f6b8b49801..d0975fcab0 100644 --- a/guix/build/meson-build-system.scm +++ b/guix/build/meson-build-system.scm @@ -22,7 +22,6 @@ #:use-module ((guix build gnu-build-system) #:prefix gnu:) #:use-module ((guix build glib-or-gtk-build-system) #:prefix glib-or-gtk:) #:use-module (guix build utils) - #:use-module (guix build rpath) #:use-module (guix build gremlin) #:use-module (guix elf) #:use-module (ice-9 match) @@ -78,42 +77,13 @@ (define* (install #:rest args) (invoke "ninja" "install")) -(define* (fix-runpath #:key (elf-directories '("lib" "lib64" "libexec" - "bin" "sbin")) - outputs #:allow-other-keys) - "Try to make sure all ELF files in ELF-DIRECTORIES are able to find their -local dependencies in their RUNPATH, by searching for the needed libraries in -the directories of the package, and adding them to the RUNPATH if needed. -Also shrink the RUNPATH to what is needed, +(define* (shrink-runpath #:key (elf-directories '("lib" "lib64" "libexec" + "bin" "sbin")) + outputs #:allow-other-keys) + "Go through all ELF files from ELF-DIRECTORIES and shrink the RUNPATH since a lot of directories are left over from the build phase of meson, for example libraries only needed for the tests." - ;; Find the directories (if any) that contains DEP-NAME.
