Re: [ESPResSo-users] 回复: Problem with installation of espresso-4.1.0

Hi Shawn,

It looks like your compiler doesn't know the C++14 standard. For example:

> /home/zhsh/sourcecode/espresso/src/utils/include/utils/Vector.hpp:
>   error: parameter declared ‘auto’
>                   [](auto ai, auto bi) { return ai * bi; });
>                           ^
>   error: parameter declared ‘auto’
>                   [](auto ai, auto bi) { return ai * bi; });
>                                    ^
>   error: ‘ai’ was not declared in this scope
>                   [](auto ai, auto bi) { return ai * bi; });
>                                                 ^
>   error: ‘bi’ was not declared in this scope
>                   [](auto ai, auto bi) { return ai * bi; });
>                                                      ^

can be reproduced with gcc v4.8.5. Many of the other error messages can 
be reproduced by more recent gcc versions with the C++11 flag. The 
minimal gcc version needed for espresso 4.1 is v4.9.0. Our build system 
does not check for compiler version numbers, instead it checks the 
compiler is C++14-capable. I'm not sure why CMake did not fail. Also, 
the CMake output should have shown a line with the compiler version, or 
the string "The CXX compiler identification is unknown".

Could you please share with us your CMake version and gcc version? The 
command lines are "gcc --version" and "cmake --version". If this is an 
issue in CMake, we will have to add a few lines in our build system.

Best,
JN
