Have you ever gotten this to work on Windows with MSVC?

[pst2154]

MSVC seems to not like many of the statements. I'm no c++ expert (which is why i was trying to use this header file obviously). Wonder if you know how to fix?

Hi,

I have not tried compiling this with MSVC. I do use C++11 features and signal handling to catch Ctrl-C which only works on Unix.

If you are still interested in getting this to work, you could

• Make sure your compiler is configured to compile C++11 correctly;
• Comment out the code regarding signal handling for Ctrl-C

Best of luck! Let me know what works so we can post it here so others can refer to it later.

VS2013 support C++11, but why does not it work?

Hi Xuson,

The errors you below are related to the SigintHandler class. It is code to catch sigint (Ctrl-C) on Unix machines. This enables interrupting the middle of a computation. This code requires compiling on a Unix machine.

However, this class is optional to use, and provided only as a convenience.

To compile on a Windows machine, you can simply comment out this class definition as well as the #include <signal.h> line.
