You need to add -L opt lib to tell ld to look there for shared objects

When you make the call to gcc it should say  g   -Wall -I home alwin Development Calculator  -L opt lib main cpp -lcalc -o calculator  not -libcalc so    I have a similar problem with auto-generated makes   You can create a soft link from your compile directory to the library directory  Then the library becomes  local    cd  compile directory  ln -s   path to libcalc so libcalc so

Add -L opt lib to your compiler parameters  this makes the compiler and linker search that path for libcalc so in that folder

Alwin Doss  You should provide the -L option before -l  You would have done the other way round probably  Try this

[c++] /usr/bin/ld: cannot find
