import error: Symbol not found

[mlove4u]

Env: OSX10.12, Python 3.6.1
Code:

import pyxpdf

Error:

How can I fix this error?
Thanks.

@mlove4u Thanks for the report!

This might be due to the fact that pyxpdf's pre-compiled wheels are built on OSX 10.15 (Azure Pipelines) which might be incompatible with older versions of OSX.

Can you try installing pyxpdf from the source?

export BUILD_LIBXPDF=true
export CFLAGS="-std=c++14"
pip install pyxpdf  --no-binary :all: -v

In case of error can you send the output of the above command.
That would be helpful

Hi @ashutoshvarma

sierra:~ kou$ export BUILD_LIBXPDF=true
sierra:~ kou$ export CFLAGS="-std=c++14"
sierra:~ kou$ pip install pyxpdf  --no-binary :all: -v

This is the output message.
