尝试构建Docker映像时，在pkg-config搜索路径中找不到软件包opencv

Question

I'm trying to build docker image, but I have this

app/utils

app/vendor/fifo/fifobuffer_v2

parkingDetection/pkgs/utils

app/pkgs/utils

app/vendor/github.com/stratoberry/go-gpsd

parkingDetection/gpsdata

gocv.io/x/gocv app/gpsdata

pkg-config --cflags opencv

Package opencv was not found in the pkg-config search path.

Perhaps you should add the directory containing `opencv.pc'

to the PKG_CONFIG_PATH environment variable

Package 'opencv', required by 'virtual:world', not found

pkg-config:

exit status 1

  apt-file search opencv.pc

gives me

libopencv-dev: /usr/lib/x86_64-linux-gnu/pkgconfig/opencv.pc

  echo $PKG_CONFIG_PATH

gives me

/usr/lib/x86_64-linux-gnu/pkgconfig/opencv.pc

How can I solve this problem?

Answer 1

I had a similar problem when I was trying to install a deep learning framework and this is how I fixed it:

Add the following to your .bashrc file:

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/lib/x86_64-linux-gnu/pkgconfig

export PKG_CONFIG_PATH

then run the .bashrc file by either

source ~/.bashrc

or 

. ~/.bashrc

I hope it works for you.

Answer 2

因此，我想我无法构建docker映像，该映像在我的PC上使用了没有opencv的ppencv
