所以我两年前已经在 python 的虚拟环境中安装了 OpenCV 库，并且它运行良好这步骤。现在我用 C 语言创建了一些图像处理程序，但每次我尝试编译时，它总是找不到 OpenCV 库。
Package checking always able to detect OpenCV
$ pkg-config --modversion opencv
3.1.0
但是如果我运行我的 make 文件
在我的 make 文件下面，linux.sh
#!/bin/sh
# if [ $# -gt 0 ] ; then
# base=`basename $1`
# echo "compiling $base"
# g++ -ggdb `pkg-config opencv --cflags --libs` $1 -o $base
# if [ $# -gt 0 ] ; then
# base=`basename $1 .c`
# echo "compiling $base"
# gcc -ggdb `pkg-config opencv --cflags --libs` $base.c -o $base
if [ $# -gt 0 ] ; then
base=`basename $1 .cpp`
echo "compiling $base"
g++ -ggdb `pkg-config opencv --cflags --libs` $base.cpp -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` -lm;
done
for i in *.cpp; do
echo "compiling $i"
g++ -ggdb `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv` -lm;
done
fi
它总是返回这个

我搜索了我的 OpenCV 库的位置，并在 /usr/local/lib 中找到了它：它包含所需的一切，例如 libopencv_aruco.so.3.1、libopencv_bgsegm.so.3.1 等。
我尝试了网上的几种解决方案，但仍然不起作用。那么，我该如何解决这个问题呢？不会破坏我的整个系统还能正常工作吗？
更新 #1 pkg-config --libs opencv 的结果
-L/usr/local/lib -lopencv_stitching -lopencv_superres -lopencv_videostab -lopencv_aruco -lopencv_bgsegm -lopencv_bioinspired -lopencv_ccalib -lopencv_dnn -lopencv_dpm -lopencv_fuzzy -lopencv_line_descriptor -lopencv_optflow -lopencv_plot -lopencv_reg -lopencv_saliency -lopencv_stereo -lopencv_structured_light -lopencv_rgbd -lopencv_surface_matching -lopencv_tracking -lopencv_datasets -lopencv_text -lopencv_face -lopencv_xfeatures2d -lopencv_shape -lopencv_video -lopencv_ximgproc -lopencv_calib3d -lopencv_features2d -lopencv_flann -lopencv_xobjdetect -lopencv_objdetect -lopencv_ml -lopencv_xphoto -lippicv -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_photo -lopencv_imgproc -lopencv_core
我再次尝试一种解决方案这里：
我执行的步骤：
sudo gedit /etc/ld.so.conf.d/Robotika.conf
然后我输入以下内容
/usr/local/lib
在那之后
sudo ldconfig
好的，根据评论，这个解决方案不适合我的情况
更新 #2 当我跑步时
$ namei -l /usr/local/lib/libopencv_aruco.so
f: /usr/local/lib/libopencv_aruco.so
drwxr-xr-x root root /
drwxr-xr-x root root usr
drwxr-xr-x root root local
drwxr-xr-x root root lib
libopencv_aruco.so - No such file or directory
未检测到库，但如果我运行：
$ namei -l /usr/local/lib/libopencv_aruco.so.3.1
f: /usr/local/lib/libopencv_aruco.so.3.1
drwxr-xr-x root root /
drwxr-xr-x root root usr
drwxr-xr-x root root local
drwxr-xr-x root root lib
lrwxrwxrwx root root libopencv_aruco.so.3.1 -> libopencv_aruco.so.3.1.0
-rw-r--r-- root root libopencv_aruco.so.3.1.0
它检测到了。
