Hi, there appears to be an issue with the elfutils package that is missing a dependency after it is installed.
To reproduce, on a profile without `xz' installed: $ guix install elfutils $ pkg-config --cflags libdw Package liblzma was not found in the pkg-config search path. Perhaps you should add the directory containing `liblzma.pc' to the PKG_CONFIG_PATH environment variable Package 'liblzma', required by 'libdw', not found or using gstreamer which depends on elfutils $ guix shell --check gstreamer pkg-config --pure $ pkg-config --cflags libdw Package liblzma was not found in the pkg-config search path. Perhaps you should add the directory containing `liblzma.pc' to the PKG_CONFIG_PATH environment variable Package 'liblzma', required by 'libdw', not found This is because elfutils has discovered an installation of the `xz' library during the configure phase (log @ http://ci.guix.gnu.org/log/jp6027624wl2f4xx5yz1vjzd2b9yvwl9-elfutils-0.183) ... checking for library containing gzdirect... -lz checking for library containing BZ2_bzdopen... -lbz2 checking for library containing lzma_auto_decoder... -llzma checking for library containing ZSTD_decompress... no ... even though it is not part of the package inputs gnu/packages/elf.scm: (define-public elfutils (package (name "elfutils") (version "0.183") ;; ... (native-inputs (list m4)) (inputs (list zlib)) ;; ... )) The `xz' package is most likely coming as an implicit input from the commencement module's %final-inputs and thus picked up by the configure script, but is never propagated. Assuming the above analysis is correct, potential solutions could be: 1. Declare `xz` as a propagated input in elfutils. 2. Pass --without-lzma to the configure script. 3. Change the build scripts so that build inputs that are only used for unpacking sources are only visible to unpack phase. Looking closer at the configure output, it appears there is an additional implicit input that is picked up by the configure script `bzip2`, thus this should also be considered. Furthermore, the configure script recommends that all compression methods should be installed RECOMMENDED FEATURES (should all be yes) gzip support : yes bzip2 support : yes lzma/xz support : yes zstd support : no libstdc++ demangle support : yes File textrel check : yes Symbol versioning : yes so perhaps option#1 above should be the preferred solution, and should also include zstd as a dep? If so, I've created the following draft to demonstrate its use >From 158b3f67fdd43b4e9b6ac1d46d27169e4f67c4de Mon Sep 17 00:00:00 2001 Subject: [PATCH] Include elfutils recommended inputs for libdw pc --- gnu/packages/elf.scm | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/gnu/packages/elf.scm b/gnu/packages/elf.scm index 414d6a2856..cfe3bd466a 100644 --- a/gnu/packages/elf.scm +++ b/gnu/packages/elf.scm @@ -109,6 +109,10 @@ (define-public elfutils (native-inputs (list m4)) (inputs (list zlib)) + ;; libdw dependencies + (propagated-inputs `(("xz" ,xz) + ("lbzip2" ,lbzip2) + ("zstd:lib" ,zstd "lib"))) (home-page "https://sourceware.org/elfutils/";) (synopsis "Collection of utilities and libraries to handle ELF files and DWARF data") -- 2.34.0 Testing with gstreamer $ pre-inst-env guix shell --check gstreamer pkg-config --pure guix shell: checking the environment variables visible from shell '/bin/bash'... guix shell: All is good!
