Question

我正在尝试在linux平台上安装Opencv。基本上，我关注http://sysads.co.uk/2014/05/install-opencv-2-4-9-ubuntu-14-04-13-10/。

但每当我尝试构建样本时，我都会收到以下错误 -

compiling contours.c
  /usr/bin/ld: cannot find -lcufft
  /usr/bin/ld: cannot find -lnpps
  /usr/bin/ld: cannot find -lnppi
  /usr/bin/ld: cannot find -lnppc

但是，我在/usr/local/cuda-7.5/中拥有所有这些文件。我正确安装了CUDA。 lspci -v -s $(lspci | grep VGA | cut -d" " -f 1)

的输出

请帮忙。

我已经通过编辑build_all.sh目录中的/usr/local/share/OpenCV/samples/c来解决了这个问题。新build_all.sh是：

#!/bin/sh

if [ $# -gt 0 ] ; then
    base=`basename $1 .c`
    echo "compiling $base"
    gcc -ggdb -L /usr/local/cuda-7.5/lib64 `pkg-config opencv --cflags --libs` $base.c -o $base
else
    for i in *.c; do
        echo "compiling $i"
        gcc -ggdb -L /usr/local/cuda-7.5/lib64 `pkg-config --cflags opencv` -o `basename $i .c` $i `pkg-config --libs opencv`;
    done
    for i in *.cpp; do
        echo "compiling $i"
        g++ -ggdb -L /usr/local/cuda-7.5/lib64 `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv`;
    done
fi
