fatal error while building

[ybkdemon]

When I tried to build project with
scons mode=release install=true
it gives the following error:
scons: Reading SConscript files ...
Building NVCC tool
scons: warning: Two different environments were specified for target src/detail/matrix/copy_operations.os, but they appear to have the same action: $SHCXX -o $TARGET -c $SHCXXFLAGS $SHCCFLAGS $_CCCOMCOM $SOURCES
File "/home/ybk/workspace/persistent-rnn/SConscript", line 45, in <module> scons: *** Multiple ways to build the same target were specified for: src/detail/matrix/copy_operations.os (from ['/home/ybk/workspace/persistent-rnn/src/detail/matrix/copy_operations.cu'] and from ['src/detail/matrix/copy_operations.cpp'])
File "/home/ybk/workspace/persistent-rnn/SConscript", line 45, in <module>

So I tried another way to build it with
source ubuntu-64-environment.sh
sudo scons install=true
it gives another error like:
scons:Reading SConscript files ...
Building NVCC tool
Installing Persistent RNN Kernels
scons: done reading SConscript files.
scons: Building targets ...

scons: *** [.debug_build/benchmark/benchmark-atomic-throughput.o] Error 1
scons: building terminated because of errors.

At first I thought it was the problem of clang++ to find c++ include files, so i write an example named new_feature to test whether clang++ can do #include <new>
#include <iostream>
#include <string>
#include <new>
class MyClass
{
public:
std::string s ="Hello, world\n"; // Non-static data member initializer
};
int main()
{
std::cout << MyClass().s;
}
Then I run it with:
clang++ -std=c++11 -stdlib=libc++ -Werror -Weverything -Wno-disabled-macro-expansion -Wno-float-equal -Wno-c++98-compat -Wno-c++98-compat-pedantic -Wno-global-constructors -Wno-exit-time-destructors -Wno-missing-prototypes -Wno-padded -Wno-old-style-cast -lc++ -lc++abi new_feature.cpp
and it runs well and gives the output file.
So I don't know why the project gives me an error like that when I try to build it...
