Symbol not found in flat namespace

See original GitHub issue

Hi all. I’m getting this error when trying to import pdftotext in a flask project and cannot figure out how to resolve it.

ImportError: dlopen(/Users/casey/PycharmProjects/virtual environments/oadoi/lib/python3.9/site-packages/pdftotext.cpython-39-darwin.so, 0x0002): symbol not found in flat namespace '__ZN7poppler24set_debug_error_functionEPFvRKNSt3__112basic_stringIcNS0_11char_traitsIcEENS0_9allocatorIcEEEEPvES9_'

My installation details are:

Mac M1
pdftotext version 2.1.5
Installed poppler with homebrew, set to version 22.04.0
Ensured poppler visible to pdftotext by setting these environment variables in my shell:

export LDFLAGS="-L/opt/homebrew/opt/openssl/lib -L/opt/homebrew/lib $LDFLAGS"
export CPPFLAGS="-I/opt/homebrew/opt/openssl/include -I/opt/homebrew/include $CPPFLAGS"

I wonder if there’s some conflict between the things you installed via brew and the things you have installed otherwise. I would suggest first trying to see if you can get it all to work with only brew, on the command line, without a separately installed copy of Python and without PyCharm.

If you’re willing to give it a try, here’s how (as best I can remember):

uninstall the Python you have
install everything via homebrew in a new terminal. Make sure you aren’t in any virtualenv when you do this: brew install pkg-config poppler python3 virtualenv
check to make sure the right python3 is being found: which python3
create a new virtualenv on the command line, pointed to that Python install. Something like python3 -m venv test_venv
activate that env: source test_env/bin/activate
pip install pdftotext
test if it works: python -c 'import pdftotext'

If it works, you can then configure PyCharm to point to that existing virtual environment.
