Hi all,
I’m writing a CMake file for a project that should be compiled both in Ubuntu
and OS X.
I want to use eclipse as IDE, gcc and C++ 11.
I read different threads that suggest how to enable C++ 11 in eclipse.
According to them I included these lines in my CMake:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall")
if (${CMAKE_EXTRA_GENERATOR} MATCHES "Eclipse CDT4")
set(CMAKE_CXX_COMPILER_ARG1 "-std=c++11" CACHE STRING "C++ version for
eclipse" FORCE)
set(CMAKE_ECLIPSE_VERSION "4.3" CACHE STRING "Eclipse version" FORCE)
endif (${CMAKE_EXTRA_GENERATOR} MATCHES "Eclipse CDT4”)
However, eclipse still set a wrong value for the symbol __cplusplus (199711L
instead of 201103L I guess).
For this reason eclipse is not able to index C++ 11 features such as shared
pointer.
Therefore I get a syntax error also if the code compiles.
Any idea on how can I address this issue?
Thanks,
Luca
