Changing LD_LIBRARY_PATH at runtime for ctypes

Question

How do you update this environment variable at runtime so that ctypes can load a library wherever? I\'ve tried the following and neither seem to work.

from c

Setting LD_LIBRARY_PATH to the path where libraries are placed won't work here and ctypes will not notice any changes. So, you need to et this at the source and run ldconfig before your script to take this into account. Moreover setting the os environment or any PATH variable in the script will have no effect.

I was facing similar issue and having spent around a day to figure this out.

#mkdir -p /etc/ld.so.conf.d/
#echo "/home/starlon/Projects/pyCFA635/lib" > /etc/ld.so.conf.d/mycustomPath.conf

#ldconfig

Then verify if the path is set by

# ldconfig -v | less

After this is done, try to run your script. This has worked for me and should work for also.
