Hello everyone,
Today I installed the latest GNU compiler g++-4.0.0 on my linux box and
started to experiment it with my C++ programs. However, any program using
blitz++-0.8 refused to compile. I re-installed blitz++-0.8 using g++-4.0.0 as
the default C++ compiler ($./configure CXX=~/gcc-4.0.0/bin/g++) but the
problem persisted. For example, I tried to compile the following program
######################## start of program ##########################
#include <iostream>
#include <blitz/array.h>
int main()
{
blitz::Array<int,2> a1(3,3);
return 0;
}
######################### end of program ############################
by doing
$~/gcc-4.0.0/bin/g++ -c -Wall -I~/blitz-0.8 foo.cpp
I got the following error message:

Can anyone tell me why this happens and how can I fix it? Thanks!
