simple g++ library path question

harry349 · 05-31-2004, 02:30 PM

I don't program that often, but last time I used g++ in RedHat 7.2, I remember it working fine for my simple programs.

I'm now sitting at RedHat 9, and it complains about missing basic identifiers such as cout and endl, from iostream, which I am including.

I'm guessing that the LIBRARY_PATH needs to be configured properly, but I wasn't sure about some details.

1. Is the LIBRARY_PATH environment variable the best way to handle this?
2. Is it recursive? i.e. if I add "/usr/include", will things in "/usr/include/g++-3" also get found?
3. Any ideas why g++ or the library path wouldn't be set to these locations by default?

Thanks.

Do you have

Code:

using namespace std;

somewhere at the beginning of your code?

Good question. I did not have it.

I was aware of but kind of forgot about namespaces; they didn't really exist back when I learned C++.

If I put "using namespace std;" after the includes (or put "std::" in front of the unknown identifiers) all is good. Thanks.
