+### Where are libraries loaded from?
+
+**Problem**
+
+I have problems with libraries loaded (eventually dynamically) from my application and I am not sure if the correct library is loaded.
+
+Is there a way to know which libraries are loaded and from where?
+
+**Solution**
+`LD_DEBUG` can output to a file all ld operations:
+
+- Set the file where you want to save the information:
+
+```
+    > export LD_DEBUG_OUTPUT=/dev/shm/my_ld_file
+```
+- Run you application `my_executable` with ld debug options set:
+
+```
+    > LD_DEBUG=libs my_executable
+```
