Dear Jessica,

You did not copy the complete error message but indeed this looks like the same compiler bug. Here is a workaround that I can suggest for both:

Look at the file simpleobseval.h, line 706:

/// ratio of two observables template <class T, class U> inline alps::SimpleObservableEvaluator<T> operator/(alps::SimpleObservableEvaluator<T> x, const alps::SimpleObservableEvaluator<U>& y) { x /= y; return x; }

and change this to

/// ratio of two observables template <class T, class U> inline alps::SimpleObservableEvaluator<T> operator/(const alps::SimpleObservableEvaluator<T>& x, const alps::SimpleObservableEvaluator<U>& y) { alps::SimpleObservableEvaluator<T> res(x); res /= y; return res; }

and make a similar change to operator* in line 665, operator- in line 641 and operator+ in line 618.

That might work around that compiler bug. Please also file a bug report with IBM.

Dear Matthias, we've made again some progress with ALPS 2 b 3 compilation. Now it stops on test compilation with the following messages, it looks like a compiler bug similar to the previous one found for examples, so I'm going to turn off building tests, too. Is it OK ? Let me know please if you need the log files. Thank you again for your help Best

Jessica
