@AmirthaKrishnan Please use "New issue" in Github to open a new issue, and please refrain from commenting on issues that are unrelated to the problem you are having.

ocrmypdf-alpine is broken at the moment since the Alpine qpdf has not upgraded to 9.0.0. I suggest using docker pull jbarlow83/ocrmypdf instead for the Ubuntu based image.

Thanks for the reply @jbarlow83
Sry for the issues i am commenting unrelated to the problem.
Problem has been fixed by using docker pull jbarlow83/ocrmypdf

9.0.1-r0 is in edge, so it should be possible to upgrade the image.

[jbarlow83]

I think it's fine now.

Just pulled the image from docker hub, still getting the same error (trying via the webinterface):

Traceback (most recent call last):
File "/usr/lib/python3.6/site-packages/pikepdf/init.py", line 10, in
from . import _qpdf
ImportError: Error loading shared library libqpdf.so.26: No such file or directory (needed by /usr/lib/python3.6/site-packages/pikepdf/_qpdf.cpython-36m-x86_64-linux-gnu.so)

After building the image by myself (libqpdf.so.26 is in edge, so it should work...) I am getting this error from the web-frontend:

Traceback (most recent call last):
File "/usr/lib/python3.6/site-packages/pikepdf/init.py", line 10, in
from . import _qpdf
ImportError: Error relocating /usr/lib/libqpdf.so.26: _ZNSt7__cxx1119basic_ostringstreamIcSt11char_traitsIcESaIcEEC1Ev: symbol not found

Ok, it is the right version now, but still does not work.

[kykim]

from the pikepdf docs

This command installs binary wheels. 64-bit wheels are available for Windows, Linux and macOS. (Except Alpine Linux.)

So, this is probably the problem.

[jbarlow83]

@kykim I wish it were that simple. From the build logs pip is already doing the right thing and building pikepdf from source.

I think the issue is that libqpdf is being compiled without C++11 and pikepdf requires C++11. On glibc this doesn't matter but it does for Alpine's musl libc.

@jbarlow83

I think it's fine now.

I am still having an issue with the latest version, 8.2.1 works fine

Hello, the :latest version is not working, getting also the pikepdf import error.

v9.0.3 is working fine
Is the latest version working for someone? Is some further setting needed?

[jbarlow83]

I do apologize for the frustrations people have had with ocrmypdf-alpine these past few months.

Is there anyone who would object to me killing off ocrmypdf-alpine in favor of the Ubuntu based jbarlow83/ocrmypdf image?

@mawi12345 - want to make sure you're part of this discussion since you contributed the alpine image.

• The main issue is that Alpine Linux doesn't use glibc.
• The size difference between Alpine and Ubuntu is not that big.
• The fact that alpine does not support manylinux Python wheels makes it a difficult platform to support for Python, because a lot of dependencies need to be hand-compiled or otherwise require special attention.
• I'm no expert on Alpine Linux.
• I'm really busy right now and will be for several months.

I'd rather have a smaller set of installations that work reliably, and the Ubuntu image is quite stable because Travis CI implicitly tests it.

Alternately, is someone willing to volunteer to maintain ocrmypdf-alpine?

[valpo]

It is fine for me. I also prefer a stable solution over a set of choices which may work or may not work.

[jbarlow83]

I've made some improvements to the Ubuntu version and removed ocrmypdf-alpine.

[mawi12345]

@jbarlow83: The ubuntu image has improved a lot since my first alpine version. I prefer the simpler way to only support one image. Drop the ocrmypdf-alpine image and keep the user friendly ubuntu image.
