TBB link with C++

Question

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

Answer 1

Agree with Oleg Nazarov.

The original link order of my project is as follows:

/usr/bin/c++ -fopenmp -O3 -DNDEBUG -ltbb test/CPUTest/QASMTest/CMakeFiles/QasmTest.dir/QasmTest.cpp.o -o bin/QasmTest lib/libSparseCalculator.a -ltbb lib/libSparseCalculator_Common.a lib/libSparseCalculator_QRAMSimulator.a lib/libSparseCalculator_SparseSimulator.a lib/libSparseCalculator_Algorithm.a lib/libfmt.a

I found that it arose the similar error in question, and only move -ltbb to the end of link cmd will help.

Answer 2

Patroklos Patroklou's answer didn't help, so I put -ltbb at the end of my command and it worked.

Ubuntu 20.04
g++-9, libstdc++-9-dev

Answer 3

Try to insert "-ltbb -std=c++11" just before -o and it should work!
