This is an attempt to work-around a couple of nasty bugs in librdbg's
Makefiles and configuration:
Configure and build RTEMS as below:
configure --enable-networking --enable-rdbg --target=i386-rtems
make RTEMS_BSP=i386ex
After a few minutes you will notice that building aborts in librdbg ....
Analysis:
1) librdbg is tried to be built, though librdbg is not supported and the
required directory hierarchy librdbg/i386/i386ex/ is not existant.
The cause for this is incorrect setting of HAS_RDBG in most
make/custom/*.cfg files (except pc386.cfg). At the moment all
custom/*.cfg files (except pc386.cfg) in general are required to contain
HAS_RDBG=no. However, having HAS_NETWORKING=no in most custom/*.cfg
files and the toplevel configure script suppress building librdbg for
all CPUs except of i386.
=> The i386ex BSP falls though this scheme and librdbg is tried to be
build (CPU=i386 and HAS_NETWORKING=yes).
2) The Makefile.ins below lib/librdbg in general support i386/pc386 only
and are not capable to be used for multiple CPUs or BSPs (RPCGEN
generates it's target and bsp-specific files into librdbg/, therefore no
other CPU or BSP can ever be built afterwards). This problem is hidden
until now, because only a single CPU/BSP pair (i386/pc386) is really
supported.
3) The Makefile.ins below lib/librdbg can delete source files due to
improper handling of source files (make clean removes the *.x files in
the source-tree when configuring inside of the source-tree).
The patch below tries to work-around these problems for the i386ex and
the pc386 BSPs. This work-around is rather fragile (it applies rpcgen
-D, I don't know how portable this is) and incomplete (all custom/*.cfg
except of pc386.cfg should contain HAS_RDBG=no), nevertheless it should
work.
