Debugging C++ in a Docker Container with CLion IDE

docker-clion-dev's Issues

How edit the dockerfile and yml file to show GUI?

I want to use clion on win10 with Remote Docker Container debugging Env(OpenCV 4) Of Ubuntu 18.04.I install Docker in my local machine(win10). Thanks to https://github.com/shuhaoliu/docker-clion-dev, I use your Dockerfile and yml file:

It works well with many C++ library,but I want to use OpenCV4 Library，I want to run this CPP file:

#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main(int argc, char* argv[]) {
    Mat src = imread("/code/001.png");

    if (src.empty()) {
        printf("cannot load images!\n");
        return -1;
    }
    namedWindow("show_photo", WINDOW_AUTOSIZE);
    imshow("show_photo", src);

    return 0;
}

It shows that: **(show images:314): Gtk-WARNING : 09:56:09.309: cannot open display:

I found some information,But they are all about entering the command line, how to modify the dockerfile and yml file?? Please master programmers help me!

My IDE is Clion on Win10,I already install Xming on win10 and knows the X0.hosts .

What should the mapping be for local debugging? Is there a way to avoid rsync-ing?

Thanks for sharing your setup, it's really helpful.
I have the above two questions regarding CLion configuration, from this part of the README:

https://github.com/shuhaoliu/docker-clion-dev#usage

Check the file mapping settings in Clion. Before each run, code will be rsync-ed to the container at a temporary location.

How should you configure the local and "remote" mapping for local debugging (source is on your dev machine)? (Partially answered in #4)

Is there a way to avoid rsync-ing, considering the source is already on the local dev machine?

Not sure what the mapping tab is supposed to look like in the last screenshot.

I am not sure what the deployment path should be. Should it also be /home/debugger

Ubuntu Cosmic doesn't currently support cmake 3.13

CMakeLists.txt has cmake version 3.13 as a dependency, but currently Cosmic supports 3.12.1-1

root SSH login does not work in some scenarios

I discovered that this line in the Dockerfile works:

RUN sed -i 's/PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config

However, for me the entry in the /etc/ssh/sshd_config file itself is still commented out (not sure if it's always a problem) and as a result still gets "access denied" when trying to SSH as root. i.e.:

$ grep -i "PermitRootLogin yes" /etc/ssh/sshd_config
#PermitRootLogin yes

An easy fix is to either update the existing sed command or add a second sed command such as:

RUN sed -i 's/#PermitRootLogin/PermitRootLogin/' /etc/ssh/sshd_config

If the entry is not commented out, the secondary sed command has no effect. Then I was able to successfully SSH once the file looked like this:

$ grep -i "PermitRootLogin yes" /etc/ssh/sshd_config
PermitRootLogin yes

Mostly posting here in case anyone else runs into this. I will submit a PR if I get a chance. Thanks!

Less transfers ?

Hello
Firs of all thanks for writing down this great solution :)

I have a lot of problems with "Deployment" sometimes files not uploaded etc. (Check options under "Deployment" to fix that)

So I'm building using local docker so I thought that I can reuse mounted path in docker instead transferring code to /tmp via SFTP.

I just added code path in exclude paths. So this way it won't transfer extra data to generate cmake-build folder.

Seems to work...
