My linux machine says: - bash: color: command not found - bash: cls: command not found - bash: pause: command not found In other words, avoid using system(), it makes your program non-portable...

You [i]do[/i] realize that your str2digit function is actually a char2digit function right? I mean if you input a string "123", it'll return 1

It depends on which file you modified. If you've changed a header-file which is included by other (source) files, all those files need to be re-compiled because they depend on the changed header. If you modify a source file which isn't 'linked' to any other files, the compiler will know …

Perhaps you're doing something illegal in a destructor somewhere? It's a bit hard to tell without seeing code. [edit] Something horrible like... [code=cplusplus] class crash { public: int foo[]; ~crash(){delete[] foo;} }; int main(){ crash cr; cout << "hi!"; return 0; }[/code] ...will probably have the same effect as your …

It's been a while since I've used fedora, but you might also need to install [icode]yum install libstdc++6[/icode] or for 64bit [icode]yum install lib64stdc++6[/icode]. I'm not sure if fedora installs them by default, although yum is pretty good in solving dependencies etc. So I'm not really sure...

First things first: What Operating System are you using?
