LD_LIBRARY_PATH, the shared lib path in linux

Question

I wrote a shared object, say libsd.so, and I put libsd.so and its header file sd.h in ~/lib.

Here is another prog

Answer 1

Without the export your declared LD_LIBRARY_PATH is only valid in the script (.bashrc). With the export it should work, but it is usually not a good idea to set your LD_LIBRARY_PATH like this.

If you don't want to install your library in the system path (e.g. /usr/lib) you should probably use a script that sets LD_LIBARAY_PATH locally and starts your application.
