Refer to this setting when you build opencv with TBB

When you build opencv with checking with_tbb option, cmake ask crrect paths about tbb.

Refer to this setting.

note, this is set for vc12 and 32bit.

TBB_ENV_INCLUDE :
/tbb2017_20170226oss_win/tbb2017_20170226oss/include

TBB_ENV_LIB :
/tbb2017_20170226oss_win/tbb2017_20170226oss/lib/ia32/vc12/tbb.lib

TBB_ENV_LIB_DEBUG :
/opencv/tbb2017_20170226oss_win/tbb2017_20170226oss/lib/ia32/vc12/tbb_debug.

TBB_VER_FILE :
/tbb2017_20170226oss_win/tbb2017_20170226oss/include/tbb/tbb_stddef.h

TBB doesn't have CMakelist.txt, go to here.

Intel Threading Building Blocks..

I downloaded the source code here -> https://www.threadingbuildingblocks.org/
and I want to build it with cmake.

But I meet this error -> ...does not appear to contain CMakeLists.txt

Looking for a long time to figure out what to do ..
I found this site -> https://github.com/wjakob/tbb

Thank you.

When VTK build with the option that Module_vtkGUISupportMFC on visual studio 2013

You have to download and install

Multibyte MFC Library for Visual Studio 2013

good luck

Including VTK when building opencv

First, we download VTK and build it.
http://www.vtk.org/download/

and
We set the path where VTK is built, when we build opencv.

Note that, we need to include the build path, not the installed path.

http://cvlecture.marearts.com/2016/12/opencv-build-shared-opencv.html
If you go to the above address, I have built VTK 7.1.
And new content will continue to be added.

Good luck!

(lucky tip) linux opencv+cuda cmake setting and build error ->nvcc fatal compute_11

About nvcc fatal compute_11 error
when build linux(ubuntu) after opencv + cuda setting using cmake

Try change cmake setting.

Cann't you see this option check Advanced box.

CUDA_GENERATION=Kepler

Add 3.2 in CUDA_ARCH_BIN

CUDA_ARCH_BIN = 3.2

long delay opencv gpu/cuda/GpuMat

When using opencv GpuMat, there is a long delay in a use of the first line code.


In this page,
http://answers.opencv.org/question/52304/long-delay-on-cvgpugpumatupload-after-upgrade-to-gtx970/
There is solution in article.

In one word.

Add 5.2 option in CUDA_ARCH_BIN table when cmake setting.
In my case, this delay problem cleared, after build by set this option.

Thank you.
