使用 CUDA 构建 OpenCV
我正在尝试使用 Visual C++ 2008 Express 版本构建 openCV 库。我从 opencv svn 服务器下载了最新的代码并使用 CMake 2.8 创建项目。我在默认目录中安装了“CUDA Toolkit 32bit”和“NPP Library 32bit”，但每次尝试构建库时，总是出现以下错误：
26>### Assertion failure at line 2135 of ../../be/cg/NVISA/cgtarget.cxx:

我正在使用 NVIDIA Geforce GT 540M 在 Acer Aspire 5742g 上构建库我不知道为什么它不想工作。我已经在配备 GTX 280 的 PC 上以相同的方式构建了库。

I am building the libraries on my Acer Aspire 5742g with the NVIDIA Geforce GT 540M and I don't know why it doesn't want to work. I already built the libraries in the same way on my PC with a GTX 280.

我不是编译最新版本 cuda 的专家
我唯一确定的是cuda 4.0支持VS2010。
下载Cuda工具包4.1并升级到VS2010。

I'm not that expert on compiling the latest versions of cuda
The only thing I'm sure about is that cuda 4.0 support VS2010.
Download Cuda tool kit 4.1 and to upgrade to VS2010.
