Mac installation - Githubissues

luizv commented 6 years ago

First, congrats on your project. I read this and I was amazed by your results and benchmarks.

I'm new to python and binding libraries, It's possible run this on mac? I got cython & poppler from homebrew with all the necessary dependences.

But it seems pdfparser doesn't find important things needed at poppler files. Any recomendation to make it work?

Looks like problems with problems in C++ compiler rather then python -
what C++ compiler are you using? - I tested only on linux with GNU C++ . If you are using XCode than assure that it supports correct standard of C++ - look here https://stackoverflow.com/questions/40076434/no-member-named-move-in-namespace-std

here are some suggestion. Check if there are any hints on net about compiling libpoppler on Mac. Or use gnu compiler.

Thank you for pointing me to the right direction. After many tries I managed to make it work.

Feedback I tried to change the compiler to g++ when installing pdfparser through pip. I tested many gcc/g++ versions, set compiling CFLAGS and a lot of stuffs. Each gave me different errors. After a while I saw an specific error saying my Python architecture was i386, and poppler was built x86_84.

I failed to grasp how I could change Python preferred architecture, but then I installed another Python interpreter with brew, and with brew's pip the pdfparser install works.

I'll investigate now how to fix my other Python installs to run pdfparser, but it's definitely not a pdfparser issue. 😅 I learned a lot at this process. Thank you again for your help. 👍
