OpenCV的与TBB配置ARM（Ubuntu的，3.0.63） [英] OpenCV configure with TBB for ARM (Ubuntu, 3.0.63)

问题描述

我试图编译TBB支持的OpenCV库为 odroid U2 （采用四核ARM Cortex-A9 MPCore的）。我有一个编译当前的OpenCV（从GitHub）无TBB没有问题。而且我也有编译TBB库弗朗来源没有问题 - <一个href=\"http://threadingbuildingblocks.org/sites/default/files/software_releases/source/tbb41_20130116oss_src.tgz\"相对=nofollow> tbb41_20130116oss_src.tgz ，我已经成功地建造TBB库：

我可以编译我自己PROGRAMM使用g ++使用此TBB库，但我不能配置OpenCV中看到这个TBB库：

你能解释一下我该怎么办呢？谢谢！

解决方案

尝试建立与opencv包含的TBB版本（BUILD_TBB = TRUE），对我的作品在odroid-X2：

  cmake的-D CMAKE_BUILD_TYPE = RELEASE -DCMAKE_INSTALL_ preFIX =的/ usr /本地/ OpenCV的-2.4-ec15d6f383e0aae -DBUILD_TBB：BOOL =1-DWITH_TBB：BOOL =1 ..
使-j 4
 

如果你做一个化妆安装时，一定要./lib/libtbb.so到的地方在那里可以找到复制，否则OpenCV的只是离开它。

I'm trying to compile OpenCV libs with TBB support for odroid U2 (with Quad core ARM Cortex-A9 MPCore). I have no problem with compile current OpenCV (from github) without TBB. And also I have no problem with compiling TBB libs fron sources - tbb41_20130116oss_src.tgz and I have successfully builded TBB libs:

I can compile my own programm with g++ using this TBB libs, but I can't configure OpenCV to see this TBB libs:

could you explain how I can do this? Thank you!

解决方案

Try building opencv with the included TBB build (BUILD_TBB=true), works for me on odroid-x2:

cmake -D CMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local/opencv-2.4-ec15d6f383e0aae -DBUILD_TBB:BOOL="1" -DWITH_TBB:BOOL="1" ..
make -j 4

If you do a make install, be sure to copy ./lib/libtbb.so to somewhere where it can be found, otherwise opencv just leaves it there.
