When using the -l option, you don't specify the leading lib or trailing .a or .so parts of the name as they're assumed by the linker. You would want to use something like -leststring to pick it up (assuming that your -L path is set correctly.

Alternately you can specify the exact filename (so no -l, just libeststring.a) as part of the object list to link (make sure the order is right relative to your .o files), but I believe in that case you would have to specify the path as the linker won't know to search your -L path. Easiest is to use -l though.
