Using scons to compile c++ file with -std=c++11 flag -

i trying compile c++ file -std=c=+11 option using scons.

file : test.cc

#include <unordered_map>  int foo() { return 0; } 

file : sconstruct

env = environment() env.append(cxxflags = '-std=c++11') #print env['cxxflags']  src_files = split('test.cc') lib_name = 'test'  library(lib_name, src_files) 

i getting following error. seems cxxflags not taking effect when g++ invoked:

g++ -o test.o -c test.cc in file included /usr/include/c++/4.8.2/unordered_map:35:0,                  test.cc:2: /usr/include/c++/4.8.2/bits/c++0x_warning.h:32:2: error: #error file requires compiler , library support iso c++ 2011 standard. support experimental, , must enabled -std=c++11 or -std=gnu++11 compiler options.  #error file requires compiler , library support \   ^ scons: *** [test.o] error 1 

i have read few postings compiling c++ files -std=c++11 option modifying "construction environment", feel have done. can please help.

thank you, ahmed.

use env.library instead of library build library construction environment.

env = environment() env.append(cxxflags = '-std=c++11')  src_files = split('test.cc') lib_name = 'test'  env.library(lib_name, src_files)
