DO not put anything you've built in any of the system libraries (/usr/lib, etc) unless you package your code as RPM for deployment. Libraries you compile for your own use would normally be put in a lib directory somewhere under your own home directory, perhaps under your project directory, and they should be referenced in your make file. .a, .o libraries that are in, say, $HOME/lib, can be referenced by -L$HOME/lib ... if these are .so libraries, if you specify the path to your /lib/ directory in the --rpath option to ld (the gnu linker) or -Wl,--rpath= when you use gcc++ to link for you, then at runtime it will look for the .so files in that path. if the programs you're compiling will be installed under /usr/local for system-wide use, then the required shared libraries should also be installed under /usr/local/something and that path should be passed to --rpath -- john r pierce, recycling bits in santa cruz
