# Generic ld.lib.so stub library
|
|
#
|
|
# This library is used to build kernel-independent dynamically linked
|
|
# executables. It does not contain any code or data but only the symbol
|
|
# information of the binary interface of the Genode API.
|
|
#
|
|
# Note that this library is not used as runtime at all. At system-integration
|
|
# time, it is transparently replaced by the variant of the dynamic linker that
|
|
# matches the used kernel.
|
|
#
|
|
# The rule for generating 'symbols.s' is defined in the architecture-dependent
|
|
# 'spec/<architecture>/ld.mk' file.
