@ -232,15 +232,15 @@ The utility code that is used by all binaries is built into a
static archive called libqemuutil.a, which is then linked to all the
binaries. In order to provide hooks that are only needed by some of the
binaries, code in libqemuutil.a may depend on other functions that are
not fully implemented by all QEMU binaries. To deal with this there is a
second library called libqemustub.a which provides dummy stubs for all
these functions. These will get lazy linked into the binary if the real
implementation is not present. In this way, the libqemustub.a static
library can be thought of as a portable implementation of the weak
symbols concept. All binaries should link to both libqemuutil.a and
libqemustub.a. e.g.
not fully implemented by all QEMU binaries. Dummy stubs for all these
functions are also provided by this library, and will only be linked
into the binary if the real implementation is not present. In a way,
the stubs can be thought of as a portable implementation of the weak
symbols concept.
