Linker returns "relocation has an invalid symbol at symbol index..."

I am trying out some code on Ubuntu. I'm trying to run the following code <!-- language: lang-c++ --> #include <cstdlib> #include <cmath> #include <ctime> #include "random.h" using namespace std; /* Function prototype! */ void initRandomSeed(); int randomInteger(int low,int high){ initRandomSeed(); double d= rand()/(double(RAND_MAX)+1); double s= d*(double(high)-low+1); return int(floor(low)+s); } double randomReal(int low,int high){ initRandomSeed(); double d=rand()/(double(RAND_MAX)+1); double s=d*(double(high)-low+1); return low+s; } bool randomChance(double p){ initRandomSeed(); return randomReal(0,1)<p; } void setRandomSeed(int seed){ initRandomSeed(); srand(seed); } void initRandomSeed(){ // to retain updated values across different stack frames! nice! static bool initialized=false; // this is executed only very first time and random value obtained from system clock! if(!initialized){ srand(int(time(NULL))); initialized=true; } } And when I try to compile the above code using `g++`, I get the following error <!-- language: lang-none --> @ubuntu:~/Chardway$ g++ random.cpp /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 10 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 1 has invalid symbol index 11 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 2 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 3 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 4 has invalid symbol index 10 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 5 has invalid symbol index 12 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 6 has invalid symbol index 12 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 7 has invalid symbol index 12 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 8 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 9 has invalid symbol index 2 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 10 has invalid symbol index 11 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 11 has invalid symbol index 12 /usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 12 has invalid symb...
