Undefined reference to 'tbb::xxxxxxxx' #29

Closed qszxluyu closed 6 years ago

qszxluyu commented 6 years ago

Error message when I am trying to use tbb::parallel_for: /usr/include/tbb/task.h:1014: undefined reference to `tbb::internal::allocate_continuation_proxy::allocate(unsigned long) const'

Error message when using tbb::taskgroup: /usr/include/tbb/task.h:450: undefined reference to `tbb::task_group_context::init()'

Head files are included, and an -ltbb flag is used in makefile. Same code succeed in compiling on an AWS instance. CW1-CW4 succeed in compiling on my machine. (Ubuntu 16.04 VMware) I've tried to reinstall the lib package.

Does anyone have an idea what could go wrong?

Did you see the post about inverting Testlibs and ld libs in the closed issues ? Did you specify -ltbb as an LDLIBS (and not a CPPFLAG) ? The latter was a stupid error on my part that cost me quite some time

Thank you, this is helpful, I didn't notice that closed case.
