When I import the PGMagick module I get this error:(from pgmagick import gminfo)(python3.6, ubuntu 16.04)thank you very much for your help.

Hi,

thank you for the report. Looks like the compiled module has bad linkage.

Have you installed it from PyPi (using pip) or compiled from source? Could you post pip's output / your compilation procedure? Do you use some special PPA repositories for python - according to this Python 3.5 is default in Xenial.

I've got apparently the same issue on MacOS:

>>> import pgmagick

I'm pasting the installation log below. Note that Boost Python was installed right before pgmagick was built: the linkage should be consistent that way. What I suspect is that Boost Python was built against Python 2.7? The Ubunto error above also looks like a Python version mismatch

This formula is keg-only, which means it was not symlinked into /usr/local,
because macOS provides an older sqlite3.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/sqlite/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/sqlite/lib

For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/sqlite/lib/pkgconfig

@ThimoNeubauer Thank you for reporting. Linking with Boost Python for python3 is always a tricky one. I currently have no access to MacOS machine, so I cannot reproduce, moreover the build pipeline for Homebrew is different from the Linux one.

@hhatto Could you look into this and maybe create a separate issue for Homebrew? Maybe is fixed for current version (I can see from the logs 0.6.5 is built).

I have a similar issue,

>>> import pgmagick as pg
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/var/www/application/deploy/shared/site-packages/pgmagick/__init__.py", line 1, in <module>
    from pgmagick import _pgmagick
ImportError: /usr/lib64/libboost_python-mt.so.1.53.0: undefined symbol: PyClass_Type

It must be something to do with the python3 and boost-python ..

JIAZHEN commented 6 years ago

@hhatto & @komackaj could you please have a look?

JIAZHEN commented 6 years ago

In my case, the linux is AWS ami which is redhat. The boost-devel package doesn't include libboost-python3x.

JIAZHEN commented 6 years ago

I solved it ... Nightmare to install it on aws ami.

I have the similar issue on Mac OS Mojave with Python 3 using pip install pgmagick using Pycharm: <module> from pgmagick import _pgmagick ImportError: dlopen(/Users/abdul/ImgSegEnv/lib/python3.6/site-packages/pgmagick/_pgmagick.cpython-36m-darwin.so, 2): Library not loaded: /usr/local/opt/boost-python3/lib/libboost_python36.dylib Referenced from: /Users/abdul/ImgSegEnv/lib/python3.6/site-packages/pgmagick/_pgmagick.cpython-36m-darwin.so Reason: image not found

how did you resolve the issue :)

I have the same issue after success install boost, harfbuzz and mapnik libraries from source with make install (Ubuntu 18.04): python3 -c "import mapnik;print(mapnik.__file__)" Traceback (most recent call last): File "<string>", line 1, in <module> File "/root/src/python-mapnik/mapnik/__init__.py", line 74, in <module> from ._mapnik import * ImportError: /usr/lib/x86_64-linux-gnu/libboost_python-py27.so.1.65.1: undefined symbol: PyClass_Type
