This PR fixes cross-platform installation failures on Windows and macOS caused by Linux-only dependencies listed in dependency files.
Although PR #97 removed the apturl blocker, installation still fails on non-Linux systems because the following Ubuntu/Linux-specific packages are included unconditionally:
Brlapi
python-apt
systemd-python
These packages are not available on PyPI for Windows or macOS, which causes pip install to fail.
What changed
Added platform_system == "Linux" markers to Linux-only dependencies in:
requirements.txt
simulations.txt
This ensures:
Dependencies are installed normally on Linux
pip safely skips them on Windows/macOS
How to reproduce
On Windows/macOS:
pip install -r requirements.txt
Before: Installation fails with
No matching distribution found for Brlapi
After: Installation proceeds successfully
Environment
OS: Windows 10
Python: 3.11.9
Fresh virtual environment
