What version of CentOS?

UstimVV commented 1 month ago

kernel version 6.6.51 centos 8

I had such issue, when naps2 executable was incorrectly placed in /usr/bin directory instead of /usr/lib/naps2. The error occurs because libpdfium.so is lazy-loaded from path ./_linux/libpdfium.so, relative to the naps2 executable. The full path is /usr/lib/naps2/_linux/libpdfium.so by default.

Executable naps2 I found in /usr/bin. I made symlink /usr/lib/naps2 -> /usr/lib64/naps2/ where I found file _linux/libpdfium.so. But I have the same error.

sT331h0rs3 commented 1 month ago

Executable naps2 should be placed in /usr/lib/naps2 directory by default (could be /usr/lib64/naps2 in some distros as well). File /usr/bin/naps2 might be a symlink to /usr/lib/naps2/naps2 though.

The other possibility is that Centos is using too old a glibc (2.28) for the pdfium build (it's supposed to only require 2.27 but I might have missed some change). I'll check later but if you want you can see what glibc version libpdfium.so depends on. https://stackoverflow.com/questions/3436008/how-to-determine-version-of-glibc-glibcxx-binary-will-depend-on

  1. Executable naps2 I put to diffrents places - no success.
  2. glibc version now 2.36

What's the output of ldd /lib/naps2/_linux/libpdfium.so?

cyanfish commented 1 month ago

That's... odd. It works fine on my Fedora VM (which also uses the RPM). At some point I might try creating a CentOS VM and see if I can track it down but I'm not sure what the problem is.

Then I use version naps2-7.1.2 I can import pdf files and output is:

ldd /lib/naps2/_linux/libpdfium.so

After update to version naps2-7.5.1 output is:
