Oh, and for what it's worth -- I suspect if nothing else, we (guile-related package maintainers) can just exclude the guile .go containing dirs from dh_strip. I expect the .go files to be well segregated in typical cases, i.e. in /usr/lib/.../guile... I mean it'd be nice if dh_strip could handle it automatically, but offhand, I don't think that's critical. -- Rob Browning rlb @defaultvalue.org and @debian.org GPG as of 2011-07-10 E6A9 DA3C C9FD 1FF8 C676 D2C4 C0F0 39E9 ED1B 597A GPG as of 2002-11-03 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4

Guile 2.0 files starts with the MAGIC "GOOF" whereas Guile-2.2 is a genuine ELF binary (\x7f followed by "ELF"). Even file(1) recognises them simply as ELF files: """ ./usr/lib/x86_64-linux-gnu/aisleriot/guile/2.2/zebra.go: ELF 64-bit LSB shared object, no machine, version 1 (embedded), dynamically linked, with debug_info, not stripped """ Thanks, ~Niels

Not sure -- though here's some additional information: https://www.gnu.org/software/guile/manual/html_node/Object-File-Format.html And I think someone mentioned file knows about it, which I'd assume means libmagic has some related code: $ file /usr/lib/x86_64-linux-gnu/guile/2.0/ccache/ice-9/futures.go /usr/lib/x86_64-linux-gnu/guile/2.0/ccache/ice-9/futures.go: Guile Object, little endian, 64bit, bytecode v2.0 -- Rob Browning rlb @defaultvalue.org and @debian.org GPG as of 2011-07-10 E6A9 DA3C C9FD 1FF8 C676 D2C4 C0F0 39E9 ED1B 597A GPG as of 2002-11-03 14DD 432F AE39 534D B592 F9A0 25C8 D377 8C7E 73A4

Rob, can you help? I don't know all the details here, but I believe that Guile uses the ELF format, for its byte-compiled files, and they *are* ELF files, but they're not "normal" executables. They contain Guile VM byte code, data sections, etc. And as such, I assume they're not strippable, at least not in the typical sense.

How would I recognise them as "non-strippable" ELF files? Note even file(1) classifies them as ELF shared object with debug info and not stripped. Related, are we sure this is not a bug/missing feature in strip(1)? Thanks, ~Niels
Bug#907061: dh_strip: Unable to recognize the format of guile 2.2 files
Source: debhelper Version: 11.3.5 X-Debbugs-CC: guile-...@packages.debian.org When I switched aisleriot to build with guile-2.2 instead of guile-2.0, dh_strip failed the build with this error: "Unable to recognise the format of the input file" `debian/aisleriot/usr/lib/x86_64-linux-gnu/aisleriot/guile/2.2/quatorze.go' I worked around the issue by excluding .go files from dh_strip but I guess this is a bug in dh_strip. https://salsa.debian.org/gnome-team/aisleriot/commit/1701f31 Thanks, Jeremy Bicha
