[Trilinos-Users] Compilation error

[Chukwudi Chukwudozie]

Hi,

I keep getting the same error messages as below.

CMake Error at
cmake/tribits/core/package_arch/TribitsGlobalMacros.cmake:1879 (MESSAGE):

  Error, C++11 support does not appear to be supported with this C++
compiler

  and/or with the C++11 flags Trilinos_CXX11_FLAGS='-std=c++11

  -expt-extended-lambda'! If the flags Trilinos_CXX11_FLAGS='-std=c++11

  -expt-extended-lambda' where set manually, then try clearing the CMake

  cache and configure without setting Trilinos_CXX11_FLAGS and let the

  configure process try to find flags that work automatically.  However, if

  these compile-time tests still fail, consider selecting a different C++

  compiler (and compatible compilers for other languages) that supports

  C++11.  Or, if C++11 support in this project is not needed or desired,
then

  set -DTrilinos_ENABLE_CXX11=OFF.

Call Stack (most recent call first):

  cmake/tribits/core/package_arch/TribitsProjectImpl.cmake:188
(TRIBITS_SETUP_ENV)

  cmake/tribits/core/package_arch/TribitsProject.cmake:93
(TRIBITS_PROJECT_IMPL)

  CMakeLists.txt:93 (TRIBITS_PROJECT)


Thanks
