fatal error: qpdf/Constants.h - pip3 install ocrmypdf and pikepdf on ubuntu win10 subsystem failed

[mhechthz]

Hi,

there was a thread with the same problem that is closed meanwhile and did not solve my problem. I try to install ocrmypdf on ubuntu LTS 18.04 subsystem for Windows 10 I run into:

src/qpdf/annotation.cpp:11:10: fatal error: qpdf/Constants.h: No such file or directory #include <qpdf/Constants.h> ^~~~~~~~~~~~~~~~~~ compilation terminated.
and subsequent errors.

What can I do?

[jbarlow83]

pip is out of date so it fails to find the current wheel for pikepdf, tries to build from source, and fails again because qpdf headers are not installed.

Pinned because this issue is common.

[Jeparre]

Try that:
python3 -m pip install --upgrade pip

Then:
python3 -m pip install pikepdf

Thanks @Jeparre I was able to resolve the same issue.

Some users may need to use a different approach than suggested by @Jeparre.

I got the same error by run 'pypy3 -m pip install pikepdf', has anyone else encountered this problem

[jbarlow83]

pypy3 is unfortunately not supported by ocrmypdf. The dependency chain is ocrmypdf -> pikepdf -> pybind11. This PR has been merged pybind/pybind11#2146 but this is not yet in a tagged version of pybind11.

I am Japanese. I am sorry for my poor writing.

I ran into the same problem trying to install img2pdf on CentOS Python 3.6. I tried the method shown by @Jeparre but couldn't do it. Also, I couldn't find it in the pip documentation.

I'm sorry for your busy schedule, but I would appreciate it if you could help me out.

[jbarlow83]

@kaitosea916 If you have CentOS and Python 3.6, it looks like you have CentOS 7. CentOS 7 was released in 2014, making it older than the earliest version of OCRmyPDF. You would have to compile about a dozen pieces of software from source to get current versions of all of OCRmyPDF's dependencies working; it would take many many hours of work.

Your best bet is to use Docker container to run the latest version.

[kaitosea916]

@jbarlow83 Thank you for your answer, and I'm very sorry I forgot to fill in the CentOS version.I am using CentOS 8.In that case, would it be possible to take the method you described?

[jbarlow83]

Easier but still a lot of hassle. Is there a reason you can't use Docker?
