Opencv build broken - tbb related? #1023

Closed fnoop closed 3 years ago

fnoop commented 3 years ago

Lots of warnings during build about TBB:

                 from /srv/maverick/var/build/opencv/modules/core/src/parallel/parallel_tbb.cpp:11:
/srv/maverick/software/tbb/include/oneapi/tbb/detail/_config.h:394:45: warning: "__TBB_CPF_BUILD" is not defined, evaluates to 0 [-Wundef]
  394 |     #define TBB_PREVIEW_FLOW_GRAPH_FEATURES __TBB_CPF_BUILD
      |                                             ^~~~~~~~~~~~~~~

  153 | #if __TBB_PREVIEW_FLOW_GRAPH_NODE_SET
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then later in build, linking fails:

Build libopencv_core.so references tbb symbols that aren't referenced, probably because no tbb is linked in:
