Link time error, I guess. But according to your original message, the  
name of the library is liballeg_unshareable.a. So you would have to  
use -k liballeg_unshareable.a, not "-klalleg_unshareable.a". The  
linker only prepends "lib" if you use "-k-lalleg_unshareable.a" (note  
the extra "-"). And if you use it with {$l } in the source, you also  
need the full exact name: {$l liballeg_unshareable.a} (because you are  
linking like a regular object file in that case, not as a library).
