# build-usbboot-static.sh - build a portable, fully-static `usbboot` for Linux.
|
|
#
|
|
# The distro's libusb-1.0.a is built WITH udev, so linking against it drags in
|
|
# libudev + libcap dynamically - which defeats portability (missing/old libudev
|
|
# on other distros). This rebuilds libusb with --disable-udev --enable-static so
|
|
# usbboot links fully static: no libusb.so, no libudev, no glibc-version pin.
|
|
# udev is only needed for hotplug events; usbboot does a one-shot vid/pid open,
|
|
# which uses libusb's sysfs backend and works without udev.

# Output: installer/vendor/linux-x86_64/usbboot (statically linked, stripped).
