Thread: Compiler Issues (Works on older not newer)

Hola Amigos:

Comin atcha for another semester! They upgraded the compilers on the systems at school and now my redhat 7.1 seems to be out of date! it compiles fine on mine, but when brought over to the school's systems i get this message:

'string' is used as a type, but is not defined as a type


for every string declaration in all of my structs...

is there some special casting i have to do? i'm mental right now so i'll let it sit overnight

thanks

It's because you are using a string from <string> but haven't declared it as a std::string, or put a using std::string or a using namespace std; in the scope of the string declaration.

IE,

illegal but older versions of gcc will compile

Code:

#include <string>

int main() {
    string a;
    return 0;
}

Legal, how it should be done.

Code:

#include <string>

int main() {
    std::string a;
    return 0;
}

hey man you rock!

i never new about that std:: prefix, i just used the old gcc..

glad you were around to help me along the way

much appreciated

how do i find out the version of gcc i have and my univ has? is there any command out there for that?

Type "which gcc" in your console window and hit enter.
Alternately, just type "gcc" by itself, or your can likely use "gcc --help" or "gcc /?".

Quzah.
