Dlib: Setup.py: How to use LDFLAGS?

Created on 30 Nov 2018 · 7Comments · Source: davisking/dlib

My PC is broken and I'm trying to install this on android using termux. Now android linker is different than the normal one so I need to compile it and link against libpython3.so. I've tried running:

LDFLAGS=" -llog -lpython3" python3 setup.py install --set 'DCMAKE_INSTALL_PREFIX=$PREFIX'

But with no results.

Any other way to install this? If I don't link it I will get this error:

ImportError: dlopen failed: cannot locate symbol "PyInstanceMethod_Type"

Thanks.

@Nannigalaxy If I remember right I installed it with cmake. I don't remember from what folder but you can check the setup.py script to check from where is installing it.. it was tools/something

@nitanmarcel curious if you found a fix for this. I am also trying to install dlib on my android using termux. but got similar error.

    import dlib
ImportError: dlopen failed: cannot locate symbol "PyInstanceMethod_Type" referenced by "/data/data/com.termux/files/usr/lib/python3.7/site-packages/dlib.cpython-37m.so"...

apt update
apt upgrade
apt install python clang fftw libzmq libzmq freetype libpng libpng pkg-config zlib libiconv  curl

wget https://files.pythonhosted.org/packages/05/57/e8a8caa3c89a27f80bc78da39c423e2553f482a3705adc619176a3a24b36/dlib-19.17.0.tar.gz
tar -xf dlib-19.17.0.tar.gz
cd dlib-19.17.0
LDFLAGS=" -llog -lpython3" python3 setup.py install --set 'DCMAKE_INSTALL_PREFIX=$PREFIX'
