Thanks for the response Ian. So, the conclusion is that my binary is stuck with unnecessary relocatable code (of a function func3() which main() doesn't call). Of course, I don't call func2() either, but I can accept that - as it is defined within an object file which I use (fun1.o) My interest in all this is to remove unused functions, and thus reduce the size of my final binary. I did find another thread on this list which dealt with removing dead code. Here's the Google cache : http://66.102.11.104/search?q=cache:5y73E-67cZAJ:gcc.gnu.org/ml/gcc-help/200 3-08/msg00128.html++site:gcc.gnu.org+removing+dead+code&hl=en I'm not sure I can do this under Solaris though - I will post an update if I manage it. Best regards, Srikanth Madani ps: Here's the entire scenario - if someone wishes to recreate it. [181]> \ls *.c fun1.c fun2.c hello.c [182]> cat fun1.c void func1() { printf("\nIn function func1()\n"); } void func2() { func3(); } [183]> cat fun2.c void func3() { printf("\nIn function func3()\n"); } [184]> cat hello.c void main() { func1(); } [185]> cc hello.c fun1.c hello.c: fun1.c: Undefined first referenced symbol in file func3 fun1.o ld: fatal: Symbol referencing errors. No output written to a.out And if I use fun2.c as well - then all goes well. [186]> cc hello.c fun1.c fun2.c hello.c: fun1.c: fun2.c: [187]> \ls a.out a.out
