My IDE says "Errors exists in required project. Continue to launch?" - c++

Question

My IDE says "Errors exists in required project. Continue to launch?". at 48% through launch attempt. But doesn't show any highlighted errors.
Im using Eclipse indigo release 2.
Some other user said this something similar happened to them, and that they had deleted files from their hard drive recently, which i did but nothing in regards eclipse or c++.
#include <iostream>
#include <string>
using namespace std;
void search(char wrd2[26]);
bool srch(char wrd[26], char ch);
int pos(char wrd[26], char ch);
int cntr(char wrd[26], char ch);
void revr(char wrd2[26], char wrd1[26]);
void chcs(char wrd2[26], char wrd1[26]);
void re_ch(char wrd2[26], char wrd1[26]);
int main()
{
char wrd1[26], wrd2[26];
int opt=0;
cout<<"Please enter two word words."<<endl;
cout<<""<<endl;
cout<<"Please insert your first word here:";
cin>>wrd1;
cout<<""<<endl;
cout<<"Enter your second word here :";
cin>>wrd2;
cout<<endl;

cin>>opt;
cout<<endl;
if (opt==1){
search(wrd2);
}
if (opt==2){
revr(wrd2,wrd1);
}
if (opt==3){
chcs(wrd2,wrd1);
}
if (opt==4){
re_ch(wrd2,wrd1);
}
if (opt==5){
cout<<"Please change your first word here:";
cin>>wrd1;
cout<<""<<endl;
}
if (opt==6){
cout<<"Please change your second word here:";
cin>>wrd2;
cout<<""<<endl;
}
}
while(opt !=7);
if(opt==7)
cout<<"good bye";
}
Does my code seems valid to you. Again there is no signs of errors on my IDE.

cnt=cntr(wrd2,ch);
x=pos(wrd2,ch);
if(fnd==true)
{
cout<<"Yes! Your character was found! :) ";
if(cnt==1)

What do i do?

I had a similar problem. Closing and reopening eclipse did it for me.
