Observed result or behaviour

First, I get an error about both --enable_bzlmod and --enable_workspace being disabled:

$ bazel build //...
Starting local Bazel server and connecting to it...
WARNING: ignoring JAVA_TOOL_OPTIONS in environment.
ERROR: Error computing the main repository mapping: error loading package 'external': Both --enable_bzlmod and --enable_workspace are disabled, but one of them must be enabled to fetch external dependencies.

If I set --enable_bzlmod, I get the following errors:

$ bazel build --enable_bzlmod //...

@davidzchen we are aware of this. We support only bazel up to 7.4 - porting iceoryx to the newest bazel version requires some effort and is currently not on our top prio list.

We would happily receive some support and a pull request here.

@davidzchen iceoryx2 does not yet support bzlmod, only the legacy workspace approach. We have users which still rely on bazel 6.2 and cannot use bzlmod. But we would appreciate a patch to introduce bzlmod to iceoryx2 as long as the legacy workspace approach remains functioning.
