Class definition causes error.

[alexBB]

I am trying to compile an fft.ccp file from this website:

http://www.librow.com/articles/article-10

Currently I have troubles with a private header file (complex.h). This file is referenced in fft.cpp.

http://www.librow.com/articles/article-10/appendix-b-1

The error I get is here:

  complex.h:11:7: error: expected identifier before ‘_Complex’

The line it points to is:

class complex{

What's wrong with the class definition?

Thanks, - Alex

What compiler are you using? It looks like it might not be standards-conforming.

[alexBB]

g++ in Ubuntu 12.04

What is the output of g++ --version ?

[alexBB]

What do you mean? There was no output. I got a compilation error.

This has nothing to do with the code. Open a shell and run g++ --version
