4.6. Using the gcc-toolset-15 to run interactive development containers

To use the gcc-toolset-15 image for interactive development, run an interactive container that mounts source code from the host.

Prerequisites

The gcc-toolset-15 image is available locally.
You have a host directory containing the application source code, for example, /home/devuser/src.
You have read and write permissions for the host directory.

Procedure

Start an interactive container that mounts the source directory and uses it as the working directory:
```
$ podman run --rm -it -v /home/devuser/src:/src -w /src <REGISTRY>/<NAMESPACE>/gcc-toolset-15:<TAG> /bin/bash
```
Replace <REGISTRY>, <NAMESPACE>, and <TAG> with your specific values.
Inside the container, verify that the source code is available:
```
# ls /src
```
Build an application using GCC Toolset 15:
```
# gcc -o myapp main.c
```
Build artifacts created in /src are stored on the host in /home/devuser/src.
When the interactive session completes, exit the shell:
```
# exit
```
Because the container was started with the --rm flag, it is removed automatically.
