更新后库的 OpenCV 链接器错误答案

【问题描述】：

我使用的是 OpenCV，但由于某种原因需要重新安装它！但是我的程序现在无法编译！我的编译脚本是：

#!/bin/sh
if [ $# -gt 0 ] ; then
#   base=`basename $1 .c`
#   echo "compiling $base"
#   gcc -ggdb `pkg-config opencv --cflags --libs` $base.c -o $base 

#   base=`basename $1 .cpp`
    echo "compiling $1"
    g++ -ggdb `pkg-config --cflags opencv` -o `basename $1 .cpp` $1 `pkg-config --libs opencv`;
#   gcc -ggdb `pkg-config opencv --cflags --libs` $base.c -o $base 

else
    for i in *.c; do
        echo "compiling $i"
        gcc -ggdb `pkg-config --cflags opencv` -o `basename $i .c` $i `pkg-config --libs opencv`;
    done
    for i in *.cpp; do
        echo "compiling $i"
        g++ -ggdb `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv`;
    done
fi

当我像./build_all.sh test10Camera.cpp 一样使用它时，输出不起作用，错误是：

compiling test10Camera.cpp

出了什么问题，我该怎么办？

错误消息告诉你究竟出了什么问题：

/usr/bin/ld: warning: libtbb.so, needed by /usr/local/lib/libopencv_core.so, not found (try using -rpath or -rpath-link)

去获取libtbb 并安装它，或者如果你已经安装了，请确保你的编译器知道在哪里可以找到它。
