# Compiling Error in Aneurysm Case

Hello,

I’m trying to compile the aneurysm case, but there is following error:

“…\src\algorithm\benchmarkUtil.hh|99|error: ‘isnan’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]|”

I have the same error in other cases, when using “util::ValueTracer”.
I’m using Palabos 1.4R1 (also tried 1.1 with same error) with Windows and Codeblocks.

I am thankful for any help.

Best regards
Andi

Try an ANSI C compatible name: _isnan
