I am trying to do some tests with TBB at HPCG benchmark. However I didn't compiled the program successfully so far. I am getting errors like these:

collect2: error: ld returned 1 exit status
make: *** [bin/xhpcg] Error 1
Compile instruction look like this:
make
/usr/bin/g++ -DHPCG_NOMPI -DHPCG_NOOPENMP -I./src -I./src/GCC_TBB -O3 -ltbb -std=c++11 -ffast-math -ftree-vectorize -ftree-vectorizer-verbose=0 -fopenmp testing/main.o src/CG.o src/CG_ref.o ....
I downloaded and install latest source code from Intel.Also I already use -ltbb and -std=c++11 at compile time and I include tbb files inside my code. I can't figure out the problem so far. Does anyone face anything like this before with Intel TBB? I am assuming that is something with the linking of library but I can't figure it out
Try to insert "-ltbb -std=c++11" just before -o and it should work!
