Hi White,

What compiler are you using?  If it is gcc, what does "gcc --version" show?

Subject: S7nodave for EPICS Manual
 
Hi,
Recently, I was going to use the S7nodave to connect the PLC device,  There was a sentence in the manual that make me confused .

The manual said :S7nodave must be compiled with a C++ compiler that supports C++ 11. For some compilers, C++ 11 support is not enabled by default. In this case, you have to add the file configure/CONFIG_SITE.local and append the appropriate compiler options to the USR_CXXFLAGS variable. An example for such a configuration file can be found in configure/EXAMPLE_CONFIG_SITE.local.
 
I have two questions about this sentence:
     1. My computer's compiler does not support C++11, can I install boost insteal of c++ 11. Do I have to install C++ compiler that supports C++ 11？
     2. How to add the file configure/CONFIG_SITE.local and append the appropriate compiler options to the USR_CXXFLAGS variable, I haven't see any example.
Thanks
White
