warning: the following paths have collided (e.g. case-sensitive paths on a case-insensitive filesystem) and only one from the same colliding group is in the working tree:
This warning occurs on a case-insensitive filesystem (like macOS’s APFS or Windows’ NTFS) when a Git repository contains files whose names differ only in case. Git detects these as potential conflicts because the filesystem treats them as identical.

```bash Option 1: Disable the tc Applet (Recommended if You Don't Need It) The tc command is for traffic control and may not be essential for your use case. Disabling it avoids the problem without patching code.
Run make menuconfig (or make config for text-based) in your BusyBox source directory. Navigate to Networking Utilities > Disable tc. Save and exit. Re-run make to build BusyBox.
Solution: Patch the Detection Script Edit scripts/kconfig/lxdialog/check-lxdialog.sh to update the test program for compatibility with modern GCC.
Open the file: nano scripts/kconfig/lxdialog/check-lxdialog.sh (or use your preferred editor). Locate the section around lines 49-55 (may vary slightly) that echoes the test code:textecho "#include CURSES_LOC main() {} EOF Change it to:textecho "#include CURSES_LOC int main(void) { return 0; } EOF This adds an explicit int return type and a return statement to satisfy stricter standards. Using void for parameters avoids potential implicit declaration issues.
Save and exit. Optionally, clean up: make clean Retry: make menuconfig
This should now detect ncurses correctly and launch the menuconfig interface.
