Further information

I'm on NixOS, I tried installing OpenSSL, but it seems deprecated. Not sure what else to try. For the record, I bought a book, site says it's an epub but it turns out to be some URLLINK.acsm file. Came here to find a solution to read my book :)

I'm having a similar issue on Linux Debian Sid. I made sure the python3-oscryto package was installed. Unlike freekvh, who's getting a "The library libcrypto could not be found" error, I'm getting the error "Error detecting the version of libcrypto". Here's the complete error stack:

I just realised now that there's a bugfix version downloadable from the mobileread forum: https://www.mobileread.com/forums/showpost.php?p=4157570&postcount=2
maybe it's worth mentioning it here on github as well? One needs to remove the plugin folder from the calibre data folder before attempting to install the bugfix version.

ezracelli · 2023-10-13T02:02:48Z

@freekvh I had the exact same issue, also on NixOS! I'm using an override to tell the custom oscrypto included by this plugin where to find libcrypto:

pkgs.calibre.overrideAttrs (attrs: {
  preFixup = (
    builtins.replaceStrings
      [
        ''
          --prefix PYTHONPATH : $PYTHONPATH \
        ''
      ]
      [
        ''
          --prefix LD_LIBRARY_PATH : ${pkgs.libressl.out}/lib \
          --prefix PYTHONPATH : $PYTHONPATH \
        ''
      ]
      attrs.preFixup
  );
})

I had to use libressl instead of openssl. When I tried openssl, I got the (different) "Error detecting the version of libcrypto" error mentioned above, but libressl worked fine.

WARNING: This will build calibre from scratch on your system, since Nix's cache doesn't include this customization. Builds in about 30 seconds on my desktop machine, but YMMV

Leseratte10 · 2023-10-13T04:39:10Z

Yeah, I should really get around to releasing 0.1.0 with all this fixed. The latest beta version here on Github ( https://github.com/Leseratte10/acsm-calibre-plugin/suites/15775400817/artifacts/900357147 ) also has this bugfix included so that one should work as well. This is the same bug as in #67. All that needs to be done is download the latest alpha version from the Github Actions page which contains a fixed oscrypto version.

mtill · 2023-10-15T06:25:31Z

Hi @Leseratte10 , I'm also facing this issue.
Unfortunately, the Link you provided ( https://github.com/Leseratte10/acsm-calibre-plugin/suites/15775400817/artifacts/900357147 ) seems to be broken ?

Best regards and thank you very much for all your efforts

Leseratte10 · 2023-10-15T06:27:22Z

The link is working fine, but only for users logged in on Github - sadly Github doesn't allow making these links public.

Thank you for your help!

Just a note that I worked around both it not being found and the version issue by editing the the libcrypto_ctypes.py file in the directory calibre had unpacked the plugin. Changed

if libcrypto_path is None:
    libcrypto_path = get_library('crypto', 'libcrypto.dylib', '42')
if not libcrypto_path:
    raise LibraryNotFoundError('The library libcrypto could not be found')

libcrypto = CDLL(libcrypto_path, use_errno=True)

to

#libcrypto_path = _backend_config().get('libcrypto_path')
#if libcrypto_path is None:
#    libcrypto_path = get_library('crypto', 'libcrypto.dylib', '42')
#if not libcrypto_path:
#    raise LibraryNotFoundError('The library libcrypto could not be found')

libcrypto = CDLL('libcrypto.so.3', use_errno=True)

as just regular loading locates this fine (memory says that I saw this was already loaded at runtime, but I am unable to duplicate that now, however, it still loads fine). And further down there was a

if not version_match:
    version_match = re.search('(?<=LibreSSL )(\\d\\.\\d(\\.\\d)?)\\b', version_string)
if not version_match:
    raise LibraryNotFoundError('Error detecting the version of libcrypto')

which obviously needs \\d+ if your crpyto version string has any components > 9 (i.e., more than one digit long). With those two changes it all just worked.

Interesting, thanks for that patch. I don't know that much about library loading so I can't comment on the 1st change too much (I will need to look into that), but the 2nd change is something that I did for Linux as well a while ago (after openssl 3.0.10 came out) so I'll add that patch for the Mac library as well.

twhitehead · 2023-12-07T13:10:10Z

No problem. I did it again just now and updated the comment to have the correct library loading line (libcrypto.so.3).

Had read through the code, and the commented code is ultimately using the ctypes library location function find_library. It is pretty over the top, invoking gcc to try and locate the library it links against when you do a -lcrypto. To quote the reference

On Linux, find_library() tries to run external programs (/sbin/ldconfig, gcc, objdump and ld) to find the library file. It returns the filename of the library file.

Anyway, figured it made much more sense to just try and load it and let the system do its standard library loading location searching. Only item is that you do need the major version number. Wouldn't be hard to loop down trying versions from 3, or even 4 or 5, though.

I ran into the same problem (also on nixos), and the fixed version from github actions has timed out and is no longer available even when logged in. So here was my quick and dirty approach to getting a working install:

clone the repo
edit bundle_calibre_plugin.sh and package_modules.sh to use #!/usr/bin/env bash rather than #!/bin/bash
comment out everything related to building keyextract, since I don't care about extracting existing keys from a windows machine or a wineprefix at present
run bundle_calibre_plugin.sh

This gets a working plugin zip, but it also needs a bit of fiddling to properly find libcrypto. nix-shell on its own isn't enough, because then whatever it does to hunt down the library finds libcrypto.so.50 but the actual call to dlopen() can't. So:

nix-shell -p libressl
env LD_LIBRARY_PATH="${NIX_LDFLAGS##* -L}" calibre

and now it works, and I've successfully activated it with an anonymous ADE account.

The link is working fine, but only for users logged in on Github - sadly Github doesn't allow making these links public.

The link is definitely dead now. New link?

Leseratte10 · 2023-12-19T05:59:59Z

I've updated the included oscrypto version again, maybe that already fixes some of the issues.

Before I add the CDLL code patch by @twhitehead (if it's still needed with the new version) I need to test that some more to make sure it doesn't break any OS and/or older Calibre versions.

In case the link expires again I've also attached the current build of the plugin (64aaca3) here: calibre-plugin.zip

zoof · 2023-12-19T13:59:21Z

Now working on Debian Bookworm.

reedstrm · 2024-02-09T02:43:52Z

Just a bump to encourage making a release - I love the fact that I no longer need to maintain Wine only to run ADE to download library books!

NathanFuller · 2024-04-30T04:45:44Z

@Leseratte10 thanks for all the work you've put into this! I tried installing the attached build from your comment above and got the error message below. Please advise?

@NathanFuller I had the same issue and have been able to fix it by going to ~/.config/calibre/plugins and deleting the ACSMInput folder. This removes the remnants of deACSM, and when you try installing again it should just work.

nydragon · 2024-06-12T10:42:44Z

Hey, I opened a PR that will allow overriding the libssl and libcrypto locations.

If this PR goes through, anyone on NixOS can use this snippet:

(pkgs.calibre.overrideAttrs (old: {
  postInstall = ''
    wrapProgram $out/bin/calibre \
        --set-default ACSM_LIBCRYPTO ${pkgs.openssl.out}/lib/libcrypto.so \
        --set-default ACSM_LIBSSL ${pkgs.openssl.out}/lib/libssl.so
  '';
}))

onatbas · 2024-10-14T23:36:52Z

I am facing these similar issues on a Mac, too.

The link above doesn't seem to lead to any build I can download. It looks like a Calibre plugin isn't simply a zip archive of the code as I've run into multiple issues. Can someone point me in the right direction as to how to make the master branch (or whichever branch) into a proper Calibre package?

FWIW, here's my trace. This repeats multiple times.

You should be able to get a zip by running bundle-calibre-plugin.sh

I'm experiencing the same error stack, and this workaround didn't work for me. It just returns the same error whether or not there is the DeACSM folder.
