N00b looking for GCC error help.

[sublimanized]

Hello all ... here is my problem. I just got the book "Teach Yourself C
++ in 21 Days"

Setup:
Fedora Core 6 - i386
GCC 4.1.1

Again, I am a complete newcomer to C++, and this is one of the first
examples out of the book. I want to know why exactly this doesn't
clean compile, and how would i fix it?

Again, I am a complete newcomer to C++, and this is one of the first
examples out of the book. I want to know why exactly this doesn't
clean compile, and how would i fix it?


$ gcc ./Func.cpp -o Func

g++ ./Func.cpp -o Func

Hello all ... here is my problem. I just got the book "Teach Yourself C
++ in 21 Days"

[snip]

You should be using "Accelerated C++" or "You Can Do It" to start in C+
+.

Setup:
Fedora Core 6 - i386
GCC 4.1.1

Again, I am a complete newcomer to C++, and this is one of the first
examples out of the book. I want to know why exactly this doesn't
clean compile, and how would i fix it?

[snip]
$ gcc ./Func.cpp -o Func

This is off-topic here, but try:

$ g++ ./Func.cpp -o Func

The problem seems you didn't link the STL code.

HTH,

Marcelo Pinto

Whenever you have linker errors ('ld' is the linker), you need to
make sure you're supplying all the necessary modules to it. How?
That's an implementation-specific question. Try gnu.g++.help NG.

Wow .... i feel like an idiot.

"g++" did the trick.

Thanks for the help, everybody.
