The target file is a dummy file used to force directory creation. I have a
pattern rules something like:
%/.mkdir:
mkdir -p $(@D) && touch $(@)
I use this technique for creating directories absolutely everywhere.
The actual chain of dependencies looks like:
everything:
/bld/tower/normanw_9.1/sparc-SunOS-5.9/dyn_dbg/CONNECT_ROOT/FSSGateway/src/FSSGateway
/bld/tower/normanw_9.1/sparc-SunOS-5.9/dyn_dbg/CONNECT_ROOT/FSSGateway/src/FSSGateway:
-lhostgateways
-lhostgateways:
/bld/tower/normanw_9.1/sparc-SunOS-5.9/dyn_dbg/lib/libhostgateways.so
/bld/tower/normanw_9.1/sparc-SunOS-5.9/dyn_dbg/host/gateways/src/manifest.o:
host/gateways/src/manifest.cpp
host/gateways/src/manifest.cpp:
/bld/tower/normanw_9.1/share/host/gateways/src/.mkdir
everything is a phony target to build everything in the tree. The -l target
is another phony target which depends on the actual library file. There is a
target specific variable defined on the library basically setting up its
linker options. The library depends on the dot-o files which are platform
specific. There are pattern specific variables set up to set compilation
options at a source directory level. The manifest.cpp target is a generated
file listing the versions to be built. It's built by a pattern rule looking
something like:
$(shr_root)/%/manifest.cpp: \
$(shr_root)/%/.mkdir
Where $(shr_root) is the root for shared targets under the build tree (we
build for different architectures with different variants, the shr_root
contains platfrom independent targets).
However, having said all that I don't think this particular combination of
dependencies is special since every source directory has a manifest.cpp file
defined in exactly the same way, and make happily get through building about
half the source before getting stuck. I could try just building the directory
which is causing the problems.
