![]() ![]() On the last page of the wizard add “Dockerfile” (mind the case) to the list of transferred files:. ![]() Select the machine running Docker in the “Remote computer” field:.Proceed with the default “Application” setting:. ![]() Start Visual Studio and begin creating a new project with the VisualGDB Linux project wizard:.We will use the demo-base image as a reference point for building containers with our demo application. This will take the original ‘debian’ image, install gcc and gdbserver on it and save the resulting image under the demo-base name. This can be done by running the following commands: The first step will be to install the latest version of docker.In this tutorial we will use Visual Studio with VisualGDB to create a simple application, place it into a docker container and debug it inside the container. You can view docker containers as lightweight virtual machines that have an independent set of user-mode components, but share the kernel resources of your host Linux machine. In this simple example we could update glibc on the second machine or recompile our program with the older version, however for bigger programs depending on multiple libraries, especially if they are not backward-compatible, could make shipping Linux binaries nearly impossible.ĭocker allows packing an application together with all its dependencies into a single independent container and running it on any other machine with docker. This happens because the behavior of memcpy() has slightly changed and the glibc maintainers wanted to ensure that programs compiled against the new versions of glibc will not run with the previous incompatible versions of the library. Dumping the symbols imported from the application will show that the memcpy() function explicitly requires glibc 2.14 or later: ![]() If we compile and run it on the machine with glibc 2.14, it will run properly: However if we try to run the same binary without recompiling on a machine with glibc 2.13, it will complain that glibc 2.14 was not found. ![]()
