The SCons project welcomes bug reports and feature requests.
The procedure may be a little different than in many open source projects: the maintainer team prefers that issues are discussed before filing. So please make sure you send email with the problem or feature request to the SCons user's mailing list, which you can join via the link below: scons-users
Once you have discussed your issue on the users mailing list and the community has confirmed that it should be filed (new issue, enhancement/feature request), then please follow the instructions the community provides to file a new issue. If it's a duplicate, you'll find the issue number, and you can add yourself as a "participant" by making a comment, or even by adding a reaction (emoji) on an existing comment.
You can explore the list of existing issues, which may include workarounds for the problem you've run into on GitHub Issues
