Python binding to EAF library

rambaut

Hi,
I have created a set of python bindings for the EAF SDK library following the pattern of Steve Marple'spython-zwoasi. It works fine on Mac OS X.

I am now trying to get it working on a Raspberry Pi (the latest Debian distro).

The command to load the EAF library:

eaflib = c.cdll.LoadLibrary("/opt/EAF_linux_mac_SDK_V1.4/lib/armv7/libEAFFocuser.so")

gives the following error:

OSError: /opt/EAF_linux_mac_SDK_V1.4/lib/armv7/libEAFFocuser.so: undefined symbol: udev_enumerate_new

sudo apt install udev gives:

udev is already the newest version (241-7_deb10u8+rpi1).

and sudo apt install libudev-dev give:

libudev-dev is already the newest version (241-7_deb10u8+rpi1).

I assume that some path to the udev library is required or the udev library needs to be loaded by ctype?

Anyone had this issue or tried this on the Raspberry Pi?

I may have fixed this issue by using:

c.CDLL("/lib/arm-linux-gnueabihf/libudev.so",mode=c.RTLD_GLOBAL)
eaflib = CDLL("/opt/EAF_linux_mac_SDK_V1.4/lib/armv7/libEAFFocuser.so",mode=os.RTLD_LAZY)

rather than cdll.LoadLibrary()
