[omniORB] linking cygomniZIOPDynamic4.dll.2 failed - "undefined reference to"

[szyk100]

Hello
I try build Omniorb with Cygwin32 but I have strange linker error. Few first lines of this error are as follow:

+ rm -f shared/cygomniZIOPDynamic4.dll.2.0
+ g++ -shared -Wl,-soname=cygomniZIOPDynamic4.dll.2,--out-implib=libomniZIOPDynamic4.dll.a,--export-dynamic,--enable-auto-import -o shared/cygomniZIOPDynamic4.dll.2.0 -L../../../../lib -L../../../../lib shared/omniZIOPDynamic.o shared/compressionDynStubs.o shared/ziopDynStubs.o -L../orbcore/shared -lomniORB4 -lomnithread -lpthread

shared/omniZIOPDynamic.o:omniZIOPDynamic.cc:(.text+0xde): undefined reference to `omniZIOP::create_compression_id_level_list_policy(Compression::CompressorIdLevelList const&)'

I know that this undefined references are in other dlls but I have no idea how to fix make files.

regards

Does it work if you edit src/lib/omniORB/ziopdynamic/dir.mk to so where
it sets LIB_IMPORTS it says:

LIB_IMPORTS := $(patsubst %,$(LibPathPattern),../orbcore/shared) \
$(OMNIORB_DLL_NAME) $(OMNIORB_DYNAMIC_DLL_NAME) \
$(OMNITHREAD_LIB) $(EXTRA_LIBS)


i.e. add the $(OMNIORB_DYNAMIC_DLL_NAME) to it.
