# Repoint the installed interpreter's RUNPATH from the absolute deps dir to a
|
|
# self-relative entry so the bundled runtime is relocatable (the deps tree,
|
|
# Flatpak /app/libpython, and AppImage $APPDIR/lib/python all keep bin/ and
|
|
# lib/ as siblings). $ORIGIN is expanded by the dynamic loader; CMake leaves
|
|
# it alone (only ${...} is expanded here). RPATH_CHANGE edits the ELF in
|
|
# place, so the new entry must not be longer than the old one: the reserved
|
|
# ${DESTDIR}/libpython/lib is at least 18 bytes even for the shortest
|
|
# supported DESTDIR (Flatpak's /app), longer than the 14-byte $ORIGIN/../lib.
|
|
# Invoked from python3.cmake with -DPYTHON_BIN=... -DOLD_RPATH=...
