undefined reference to 'scalable_free'

Hello

I have installed individual free versions of parallel studio xe both in Windows (Visual Studio) and in my Linux systems. I made a program that uses since I am using scalable_malloc and scalable_free inside my functor object. My program compiles and runs successfuly in Visual Studio, but When I try compiling it in Linux system (after setting environment), I get this error:

icc -openmp histogram.cc -o histogram -ltbb

/tmp/icc8Kgyh5.o: In function `tbb::internal::start_reduce<:BLOCKED_RANGE>, histogram_tbb, tbb::auto_partitioner const>::execute()':

/tmp/icc8Kgyh5.o: In function `tbb::internal::finish_reduce::execute()':

I wonder whats problem with scalable_allocator here, Can anyone help please ?

Hello,
Thanks for contacting us with questions. You need to link it to another library called libtbb_malloc.so. So your compiler command line would be

icc -openmp histogram.cc -o histogram -ltbb -ltbb_malloc

Please let me know if you have any questions.

Thanks,
Krishna
