Python binding issues when importing gpiod #44

Closed lucalenardi closed 9 months ago

lucalenardi commented 5 years ago

Hello!

Thanks for the nice work.

We are trying to install libgpiod with its Python bindings on a Beagle Bone Black – a ARMv7 32 bit SBC. The distribution is a Debian Stretch 9.9, Kernel version is 4.14.93-bone-rt-r17.

Installed Python versions are 3.5 and 3.6.

We tried to compile and run the lib for both the system Python (3.5) and in a virtualenv with Python3.6.

./autogen.sh --enable-tools=yes --prefix=<install path> --enable-bindings-python CFLAGS="-fPIC" make make install ldconfig

Everything looks fine, configuration doesn't report any issue and also building stages. But as soon as we load a Python REPL and import gpiod we get the following exception:

ImportError: /usr/local/lib/python3.5/dist-packages/gpiod.so: unexpected reloc type 0x03

Anyone gets the same problem? Do you have any clue why it happens? Any suggestion?

I guess your python interpreter is not built with CFLAGS=-fPIC
