Hello, I'm trying to make a wireshark package for an old 32bit system where I cannot install guix but it always fails with the same error. This is the command I'm using: guix pack -S /opt/gnu/bin=bin --target=i686-pc-linux-gnu wireshark And this is the error I get: starting phase `remove-extra-references' Backtrace: 13 (primitive-load "/gnu/store/304qy7gcwfsfsfxi9x98j5kw7i2…") In ice-9/eval.scm: 191:35 12 (_ _) In srfi/srfi-1.scm: 863:16 11 (every1 # …) In /gnu/store/71d3rwa514j7vy5l4vfivf68g5yxibvl-module-import/guix/build/gnu-build-system.scm: 711:27 10 (_ _) In ice-9/eval.scm: 619:8 9 (_ #(#(#(#(#(#(#) …) …) …) …) …)) In ice-9/boot-9.scm: 841:4 8 (with-throw-handler _ _ _) In ice-9/ports.scm: 444:17 7 (call-with-input-file _ _ #:binary _ #:encoding _ # _) In /gnu/store/71d3rwa514j7vy5l4vfivf68g5yxibvl-module-import/guix/build/utils.scm: 610:26 6 (_ _) 636:26 5 (_ # …) In srfi/srfi-1.scm: 466:18 4 (fold # …) In ice-9/eval.scm: 202:51 3 (_ #(#(#(#(#(#(# …)) …) …) …) …)) 163:9 2 (_ #(#(#(#(#(#(# …)) …) …) …) …)) In unknown file: 1 (string-append "incpth='" #f "/include'\n") In ice-9/boot-9.scm: 752:25 0 (dispatch-exception _ _ _) ice-9/boot-9.scm:752:25: In procedure dispatch-exception: In procedure string-append: Wrong type (expecting string): #f builder for `/gnu/store/szkpdjdxalwb793kkbfjibvhxki33x8l-perl-5.26.2.drv' failed with exit code 1 guix pack: error: build failed: build of `/gnu/store/szkpdjdxalwb793kkbfjibvhxki33x8l-perl-5.26.2.drv' failed Since it seems related to perl, I tried running the same guix pack command for perl only, and it fails with the same error. I found a reference in the IRC logs about the same kind of error with another package, but I can't tell if it's really related or not. I'll still paste that reference here just in case: https://gnunet.org/bot/log/guix/2015-07-14#T699278 Any clue on how I could debug that ? Thanks
