Fun = figuring out shared library deps on linux. Not…
This useful article (Program Library-HOWTO) talks about how lib files are discovered and what you can do to force them to be found.
LD_LIBRARY_PATH which I’ve seen many times before, allows you to specify a library ahead of others so you can do
LD_LIBRARY_PATH=.:/my/better/lib.so:$LD_LIBRARY_PATH
If you want to see which libraries a process is using then do
ldd /path/to/your/process
There is still a magic to how those libraries then link off and refer to others but this is considerably more than I knew 24 hours ago 🙂
