检查OpenCV是否用TBB编译 [英] Check if OpenCV is compiled with TBB

问题描述

如何检查Linux计算机上安装的OpenCV库是否针对TBB库编译?

How can I check if the OpenCV libraries installed on my Linux machine are compiled against TBB libraries or not?

推荐答案

使用 ldd 打印* libopencv_core *的共享库依赖项:

Print the shared library dependencies of *libopencv_core* using ldd:

ldd /usr/local/lib/libopencv_core.so

您应该在列表中看到TBB.

And you should see TBB on the list.

如果您使用的是Mac OS X，则等效为 otool -L ，在我的系统上，其输出为:

If you were on Mac OS X the equivalent is otool -L, and on my system it outputs:

/Users/karlphillip/installers/OpenCV-2.4.2/build/lib/libopencv_core.2.4.dylib (compatibility version 2.4.0, current version 2.4.2)
libtbb.dylib (compatibility version 0.0.0, current version 0.0.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

因此，根据上面的输出，我的OpenCV安装被构建为支持TBB. ; D

So according to the output above, my OpenCV installation was built to support TBB. ;D
