OpenCV2.3.1 appears: "Cannot start this program because tbb_debug.dll is missing from the computer..." problem solution

Problem Description:

When I use Win7_32 bit, VS2008, OpenCV2.3.1, I get: "This program cannot be started because tbb_debug.dll is missing from the computer. Try reinstalling the program to solve the problem".

As shown below

Solution:

Method 1: Download and install

1. Download the http://www.threadingbuildingblocks.org/... ss_win.zip file and unzip it.

2. Enter the ...\bin\ia32\vc10 folder in the decompressed file to find the tbb_debug.dll file.

3. Copy the tbb_debug.dll file to the following directory and add the following path to the environment variable path.

      32位系统 & VC2008：D:\Program Files\OpenCV2.3.1\opencv\build\common\tbb\ia32\vc9

      32bit system & VC2010: D:\Program Files\OpenCV2.3.1\opencv\build\common\tbb\ia32\vc10

Method 2: Copy and rename

1. Copy and rename tbb.dll in the \opencv\build\common\tbb\ia32 \vc9 directory to tbb_debug.dll.

2. This step is the same as step 3 in method 1.
