Hi Einar,
The problem is not a blitz problem but a compatibility problem between
icc 8.1 (and not 8.0) and g++. icc 8.1 uses the g++ headers but the flag
-strict_ansi can not be used...
You can try to compile the following "ansi" piece of code
//hello.cc
#include <iostream>
int main()
{
std::cout << "Hello world!" << std::endl;
}
with the command "icpc --strict_ansi hello.cc" it will fail...
A work around is to remove the option --strict_ansi from default preset
Try to run configure with the following options
./configure --disable-cxx-flags-preset CXX=icpc CXXFLAGS="ansi"
That should do it.
Cheers,
Patrick
